Dear planetarians,<br />

This year, the Adler Planetarium in<br />

Chicago hosts the IPS 2008. Participants<br />

from all over the world<br />

will meet for an exchange of ideas,<br />

and manufacturers of planetarium<br />

equipment will present their concepts,<br />

strategies and new products.<br />

We of <strong>Carl</strong> <strong>Zeiss</strong> have consistently<br />

advanced our products<br />

along our strategic line. On the<br />

one hand, our best efforts are devoted<br />

to the upkeep and advancement<br />

of our classical star projectors,<br />

while on the other hand we<br />

offer new digital projection solutions<br />

– not just any solution but<br />

the best for each respective dome<br />

size, and that at reasonable prices.<br />

Granted, this is an exertion (with<br />

regard to both manpower and<br />

costs) not every manufacturer can<br />

afford or would undertake, but our<br />

efforts are justified by success: 27<br />

high-caliber planetarium project<br />

contracts landed (and some of<br />

them already implemented) within<br />

two years make up an unprecedented<br />

boom. 70% of these<br />

projects are combinations of a star<br />

projector with a digital full-dome<br />

projection system based on our<br />

powerdome platform. The integrated<br />

control of analog and digital<br />

planetarium projection was first<br />

demonstrated in our 8 m dome in<br />

Melbourne in 2006, where we<br />

showed how the star projector<br />

and the digital planetarium, i.e.<br />

SKYMASTER ZKP 4 and SPACEGATE<br />

Quinto, complement each other in<br />

an intelligent way. Meanwhile, integrated<br />

control also works with<br />

our STARMASTER and UNIVERS-<br />

ARIUM machines. More and more<br />

planetarians realize that no digital<br />

system can convey the emotional<br />

impact of the starry sky produced<br />

by our glass fiber projectors.<br />

Besides developing its innovative<br />

power, <strong>Carl</strong> <strong>Zeiss</strong> also cultivates<br />

its long-term customer relations.<br />

It is not the quick deal we<br />

are out for, but one that yields a<br />

long-term benefit for both parties.<br />

This calls for frankness and sincerity.<br />

We do not, for example, leave<br />

the customer in the dark about the<br />

operating costs of a digital fulldome<br />

system, which can be much<br />

higher than those of a classical star<br />

projector. We disclose the upsides<br />

and downsides of the various<br />

video projectors, and inform about<br />

realistic life expectancies of system’s<br />

components.<br />

We continually test digital<br />

video systems of different makes<br />

and based on different technologies.<br />

Our measurements prove<br />

that the brightness and contrast<br />

performances of none of the projectors<br />

tested come up to the<br />

specified data, and differ considerably<br />

between units of the same<br />

model. This impairs the quality of<br />

the full-dome image, of course. A<br />

great number of pixels specified<br />

for a single projector is no guarantee<br />

for high image definition,<br />

which is substantially influenced<br />

by color fringes, edge blur and<br />

distortions caused by cheap optics.<br />

This proved by ADLIP HD, our<br />

laser projection system, which<br />

delivers the most impressive fulldome<br />

image even on large domes,<br />

although its nominal specification<br />

is below those of other systems.<br />

This observation has been confirmed<br />

by comments and evaluations<br />

made by our customers.<br />

We regard the dialog with our<br />

customers as an important prerequisite<br />

for optimizing our products.<br />

In 2007 we established the powerdome®Workshop<br />

as a new communication<br />

platform, in which our<br />

customers can train hands-on,<br />

practice-oriented operation of the<br />

powerdome®Systems and gather<br />

first-hand experience with the image<br />

generator and its upsides and<br />

downsides; at the same time, this<br />

gives us their feedback about the<br />

convenience of system handling.<br />

We encourage our customers to<br />

have an influence on further developments.<br />

In addition, the<br />

powerdome®UserGroup we initiated<br />

provides a forum for our customers<br />

to communicate with each<br />

other and involve <strong>Carl</strong> <strong>Zeiss</strong> in their<br />

discussions.<br />

<strong>Carl</strong> <strong>Zeiss</strong> guarantees quality,<br />

reliability and sustainability for all<br />

its products. This is honored by<br />

the market, as evidenced by our<br />

full order books. Thanks to topflight<br />

sales figures, <strong>Carl</strong> <strong>Zeiss</strong> has<br />

created around thousand new<br />

jobs worldwide and was elected<br />

Germany’s Best Employer. We<br />

would be pleased to see your success<br />

following in the wake of ours.<br />

Yours sincerely,<br />

Wilfried Lang<br />

New Developments<br />

Video Projectors vs.<br />

<strong>Night</strong> <strong>Sky</strong> <strong>Contrast</strong>?<br />

Ralf Hasse<br />

A black background is a factor<br />

of extremely critical importance<br />

to planetarium applications. The<br />

problem has existed ever since<br />

the projection planetarium was<br />

invented at <strong>Carl</strong> <strong>Zeiss</strong>. The sky<br />

photoplates used in first projection<br />

experiments brightened up<br />

the dome background far too<br />

much. The solution found then<br />

was to represent stars by pinholes<br />

perforated into copper foil. Today,<br />

<strong>Carl</strong> <strong>Zeiss</strong> fiber-optic projectors<br />

deliver the best contrast conceivable.<br />

For slide projection, partial<br />

covering and Kodalith sandwich<br />

masks helped. The culprits today<br />

are video projectors, which dispel<br />

the illusion of night with their<br />

background brightness. They just<br />

cannot provide the contrast<br />

needed for depicting a starry sky<br />

– with two exceptions: the technically<br />

obsolete, low-light-level<br />

CRT technology, and the high-end<br />

Laser Display Technology of the<br />

<strong>Carl</strong> <strong>Zeiss</strong> powerdome®ADLIP system<br />

[1] for top-quality full-dome<br />

projection.<br />

Other approaches to high-contrast<br />

projection on the basis of<br />

technologies such as GLV and<br />

LCoS, though under development<br />

for many years, have failed to attain<br />

the target specifications or<br />

marketability.<br />

Competence<br />

In recent years <strong>Carl</strong> <strong>Zeiss</strong> has developed<br />

comprehensive knowhow<br />

in technologies and optical<br />

systems for video display onto<br />

planetarium domes, and consistently<br />

pursues the goal of enabling<br />

night sky contrast by means of<br />

tried-and-approved chip technologies.<br />

The forthcoming powerdome®<br />

VELVET projector will, for the first<br />

time, harness the stable DLP ® technology<br />

of Texas Instruments<br />

(which has millions of applications<br />

worldwide) to present an absolutely<br />

black background with a<br />

<strong>Carl</strong> <strong>Zeiss</strong> system. And when we<br />

say “black” we mean it. VELVET<br />

will accomplish this while retaining<br />

all the familiar advantages of<br />

this technology.<br />

Status<br />

The requirement of high contrast<br />

for a video projector makes sense.<br />

The greater the difference between<br />

maximum and minimum<br />

brightness, the more brilliant is the<br />

projection. According to manufacturers’<br />

specifications, projectors<br />

on the market today have contrast<br />

ratios of 15,000 : 1 and over.<br />

Should this not be enough?<br />

Looking for suitable projectors<br />

for our powerdome®EDITION solutions,<br />

we first verified the manufacturers’<br />

specifications. The result<br />

was disappointing: None of the<br />

projectors tested reached the specified<br />

contrast. Moreover, the projectors<br />

of one and the same model<br />

varied considerably in contrast. The<br />

measurements of residual light in a<br />

black “image”, then, are quite sobering.<br />

Even in projectors that<br />

promised high contrast, the residual<br />

background brightness is<br />

hardly lower. What is worse, the<br />

background is mottled rather than<br />

uniformly gray.<br />

The results of our measurements<br />

were not altogether surprising.<br />

Home cinema or, not to mention,<br />

business projectors need not meet<br />

the requirements of multichannel<br />

projection in a completely dark<br />

room. Variations between such<br />

projectors with regard to contrast,<br />

white level and color do not really<br />

matter.<br />

In full-dome projection, they<br />

do. Any deviation in image parameters<br />

between the projectors of a<br />

set deteriorates the overall fulldome<br />

image. The effect is known<br />

from panorama and all-sky slide<br />

projections. If the color temperature<br />

of a single projector lamp differs,<br />

or if the slides have been exposed<br />

differently or are faded, the<br />

partial images fail to match.<br />

What is to be done, then? A<br />

thorough investigation into the<br />

technologies for full-dome projection<br />

and the verification of manufacturers’<br />

data will soon reveal that<br />

there is no absolutely perfect solution.<br />

Even if investment and operating<br />

costs were no consideration,<br />

the upsides and downsides<br />

of the various technologies have<br />

to be weighed up. Nobody can<br />

help defining their own specific<br />

demands on full-dome projection.<br />

Demands<br />

What projection solutions do you<br />

expect to get from <strong>Carl</strong> <strong>Zeiss</strong>? <strong>Carl</strong><br />

<strong>Zeiss</strong> has made itself a name because<br />

of its claim for excellence.<br />

Nobody can expect that <strong>Carl</strong> <strong>Zeiss</strong><br />

will be content with cheap components<br />

at the expense of quality<br />

and reliability. On the contrary,<br />

our customers are aware that<br />

product developments at <strong>Carl</strong><br />

New Developments<br />

<strong>Zeiss</strong> are governed by perfection,<br />

precision and commitment. It is to<br />

be expected, then, that <strong>Carl</strong> <strong>Zeiss</strong><br />

sets itself demanding goals for its<br />

full-dome projection systems.<br />

Accordingly, what should such<br />

a system be like? It should feature<br />

high definition, sufficient brightness<br />

and brilliant color rendition.<br />

These three criteria encompass all<br />

other parameters: high resolution,<br />

a homogeneous image, high contrast,<br />

etc. In Innovation Planetarium<br />

Special No. 5, Deter and<br />

Schorcht [2] explained the reasons<br />

why contrast, of all parameters, is<br />

of paramount importance. If we<br />

add to this the fact that the night<br />

sky, the most significant element<br />

of a planetarium, rendered with a<br />

video projector is not nearly comparable<br />

with the brilliance of a fiber-optic<br />

sky, it becomes clear that<br />

<strong>Carl</strong> <strong>Zeiss</strong> cannot aim at anything<br />

less than the perfect combination<br />

of optical-mechanical sky projection<br />

and video projection. Implementing<br />

this means assimilating<br />

the contrast or, strictly speaking,<br />

the background brightness of<br />

video projection to that of the star<br />

projection, resulting in video projection<br />

with night-sky contrast, i.e.<br />

with absolutely black background.<br />

Solution<br />

The VELVET video projector is a<br />

<strong>Carl</strong> <strong>Zeiss</strong> in-house development.<br />

The contrast enhancement is<br />

based on the special optics design,<br />

which excludes scattered light and<br />

a gray background from the start.<br />

The measurable on/off contrast<br />

ratio exceeds 1,000,000 : 1.<br />

This value is implemented in the<br />

image and has been verified by<br />

means of certified measuring<br />

equipment.<br />

VELVET high-contrast projector for powerdome, a DLP video projector with truly black<br />

background<br />

Thus, <strong>Carl</strong> <strong>Zeiss</strong> offers the only<br />

DLP ® projector worldwide to feature<br />

a contrast ratio comparable<br />

to glass-fiber star projection. VEL-<br />

VET is conceived for use in the<br />

planetarium, whether as a single<br />

projector for standard videos or in<br />

a set for full-dome projection.<br />

VELVET delivers a high-definition,<br />

steady, brilliant image as<br />

known from common DLP ® projectors,<br />

but with a completely<br />

black background: the perfect illusion<br />

of boundless space as in<br />

glass-fiber star projection.<br />

Manufacture<br />

All optical components for VEL-<br />

VET will be manufactured at <strong>Carl</strong><br />

<strong>Zeiss</strong> in Jena, the group’s competence<br />

center for fabricating highprecision<br />

aspheric and free-form<br />

surfaces, where self-designed<br />

manufacturing and measuring<br />

processes and equipment are ingeniously<br />

combined with commercially<br />

available ones. For<br />

making free-form surfaces, stateof-the-art<br />

CNC grinding and polishing<br />

machines and local correction<br />

polishing techniques are<br />

available, which ensure the ultimate<br />

in form accuracy in a batch<br />

production process. These manufacturing<br />

capabilities are the decisive<br />

prerequisites for providing<br />

the projector optics with a freeform<br />

functional surface, the basis<br />

of contrast optimization.<br />

While VELVET is unique for its<br />

black background, its other characteristics<br />

are tailored to use in<br />

the planetarium as well.<br />

Illumination<br />

The illuminating system is separate<br />

from the image generator. The<br />

light source is arranged so that<br />

oblique installation positions in<br />

the domed auditorium are no<br />

problem. The lamp remains in its<br />

optimum position of use, which<br />

prolongs its service life. Lamp<br />

change is accomplished quickly<br />

and easily.<br />

The principle of a separate illumination<br />

unit allows scaling of the<br />

lamp’s output power. In future, the<br />

lamp can be replaced with one of<br />

higher power or a different type<br />

of light source.<br />

Colors<br />

VELVET uses a six-segment color<br />

wheel and employs the latest<br />

BrillantColor technology by<br />

Texas Instruments. Utilizing the<br />

spectrum of the projection lamp,<br />

this technology expands the<br />

gamut of colors and improves<br />

color saturation. It permits mixing<br />

of other primary colors (as turquoise,<br />

magenta and yellow) in<br />

addition to red, green and blue.<br />

This reduces mutual color influences<br />

and excludes the color<br />

break up in fast scenes, experienced<br />

with conventional DLP ®<br />

technology.<br />

Resolution<br />

VELVET employs the HDTV chip<br />

technology made available by Texas<br />

Instruments. At present, the projector<br />

operates with 1080 picture<br />

lines, but it is ready to accommodate<br />

the next chip generation with<br />

1200 lines as soon as this becomes<br />

available commercially. Both the<br />

imager and all optical components<br />

of the projector are designed to<br />

work with this picture format.<br />

An arrangement of six VELVET projectors<br />

will achieve a resolution for<br />

3k to 4k video output, the highest<br />

in present-day practice. For even<br />

higher resolution, arrangements<br />

with more projectors can be implemented<br />

without detriment to background<br />

blackness or edge blending<br />

quality. Costs excepting, there are<br />

practically no restrictions any longer<br />

for scaling the projection system.<br />

Homogeneity<br />

The HDTV aspect ratio affords<br />

ample space for overlapping the<br />

image channels. Compared to the<br />

1400 x 1050 chip format, this improves<br />

the homogeneity of the fulldome<br />

image.<br />

Thanks to the outstanding black<br />

level of the background, blending<br />

masks otherwise needed to eliminate<br />

disturbing overlap zones between<br />

the partial images can be<br />

dispensed with. Thus, the powerdome®ImageGenerator<br />

itself controls<br />

the geometry and edge blending<br />

of the image fields. This ensures<br />

the best possible edge blending<br />

quality and the flexibility required<br />

for arranging the projectors.<br />

Lenses<br />

<strong>Carl</strong> <strong>Zeiss</strong> only uses dedicated<br />

lenses for its planetarium products.<br />

The customer will not find<br />

any standard, mass-market lenses.<br />

Rather than a matter of snobbery,<br />

this is simply needed for excellent<br />

projection. TESSARs, COSMO-<br />

GONs and STELLAGONs are intended<br />

for perfect star projection,<br />

whereas outstanding digital images<br />

are projected with special<br />

lens developments, starting with<br />

the SCANLATAR for ADLIP systems<br />

up to the DIGIGON series (DIGI-<br />

GON 126, DIGIGON 178 and DIGI-<br />

GON 115).<br />

The latest lens of this series,<br />

DIGIGON 80 Vario, has been designed<br />

specially for VELVET. It<br />

goes without saying that it allows<br />

for the most exacting demands on<br />

contrast and imaging quality. The<br />

DIGIGON 80 Vario is equipped<br />

with zoom optics, focusing control<br />

and motor-driven iris diaphragm<br />

to provide flexibility for<br />

dome projection – the projection<br />

fields can be optimally adapted to<br />

the conditions of the particular<br />

dome. Consistently high quality is<br />

ensured by measurements and adjustments<br />

integrated in the manufacturing<br />

process.<br />

Thanks to its modular design,<br />

this high-end lens can also be used<br />

for HDTV projectors of the powerdome®EDITION<br />

series.<br />

The performance features of<br />

this lens are vital for pleasing and<br />

convincing full-dome images produced<br />

with <strong>Carl</strong> <strong>Zeiss</strong> powerdome®Systems.<br />

They ensure that<br />

your audience gets captured by<br />

your contents and messages rather<br />

than being distracted by technical<br />

deficiencies.<br />

The projection planetarium has left<br />

its mark all over the globe since<br />

1923. After 1945, the large projection<br />

machines were joined by<br />

small and medium-sized ones suitable<br />

to bring astronomy to schools<br />

and universities. Around the turn<br />

of the millennium, digital projection<br />

systems have begun to expand<br />

the spectrum of dome projection<br />

techniques.<br />

Among all competitors, <strong>Carl</strong> <strong>Zeiss</strong><br />

offers the most comprehensive and<br />

highest-quality range of systems for<br />

optical-mechanical and digital dome<br />

projection. As an outstanding feature,<br />

both types can be coupled and<br />

used jointly in astronomy shows, still<br />

the most important subject matter in<br />

a planetarium.<br />

Projection<br />

Since the launch of its latest design,<br />

the new SKYMASTER ® ZKP 4<br />

small-dome planetarium, <strong>Carl</strong> <strong>Zeiss</strong><br />

now offers fiber-optic projection<br />

machines for any dome size between<br />

6 and 35 m in diameter. The<br />

technology of illuminating each<br />

individual star through a separate<br />

glass fiber provides the benefit of<br />

a sky projection of unmatched brilliance<br />

and brightness. Forget about<br />

dark adaptation times. The stars<br />

remain to be visible even during<br />

events requiring a certain level of<br />

ambient light.<br />

UNIVERSARIUM<br />

UNIVERSARIUM ® Model IX is the<br />

most powerful large-dome planetarium.<br />

The latest customers of<br />

this flagship model are the longstanding<br />

Beijing Planetarium and<br />

the new Science Center in Nagoya,<br />

Japan, with the world’s largest<br />

planetarium dome.<br />

STARMASTER<br />

With its fiber optics and controlled<br />

shutters, STARMASTER is the model<br />

of choice for medium-sized<br />

domes. The latest version, the STAR-<br />

MASTER StarBall, concentrates on<br />

the analog projection of the stars,<br />

while leaving the projection of the<br />

planets and all didactic features to<br />

the digital system controlled by<br />

powerdome. The star brightness<br />

delivered by STARMASTER SB can<br />

be recommended for domes up to<br />

24 m in diameter. The Charles<br />

Hayden Planetarium in Boston,<br />

USA, and the new facility in Santo<br />

Andrè, Brazil, have chosen the<br />

STARMASTER or STARMASTER SB,<br />

respectively, as their star projectors.<br />

SKYMASTER ZKP 4<br />

SKYMASTER ® ZKP 4 is distinguished<br />

by fiber optics, digital<br />

planet control and a user-oriented,<br />

highly flexible operating<br />

system. Within a mere two years,<br />

it has become the best-selling<br />

projection system for small planetariums<br />

in Europe, America and<br />

Asia.<br />

dome projection systems, with or<br />

without combination with an optical-mechanical<br />

planetarium projector.<br />

The powerdome systems<br />

incorporate in-house products as<br />

well as third-party projectors. They<br />

are all controlled by the common<br />

powerdome platform, the software<br />

Powerdome®SPACEGATE employs<br />

the DLP ® technology to supply a<br />

pin-sharp image impression in<br />

domes sized up to 12 m. The projectors<br />

are arranged in the center<br />

of the domed auditorium, close to<br />

the planetarium projector to avoid<br />

partial obscuring by the latter. The<br />

system is available in two versions:<br />

SPACEGATE Duo, two-channel solution<br />

for smaller domes, and<br />

SPACEGATE Quinto with five projectors<br />

for larger domes or more<br />

ambitious installations. Most SKY-<br />

By their specifications and their<br />

optics, commercial video projectors<br />

are not intended for projection<br />

onto a spherical dome surface<br />

and, thus, less than optimum for<br />

planetarium use. With regard to<br />

some parameters (e.g., brightness)<br />

and to price, though, they may<br />

have advantages that may be of<br />

prime importance for certain planetarium<br />

projects. <strong>Carl</strong> <strong>Zeiss</strong> offers<br />

such custom solutions under the<br />

name of powerdome®EDITION.<br />

Examples of customized projector<br />

configurations are the planetarium<br />

of L‘Hemisfèric in Valencia<br />

(Spain) and the new planetariums<br />

in Jeju (Korea) and Cosenza (Italy).<br />

Three Steps to Projection<br />

Top:<br />

Resources window with<br />

opened video register.<br />

Bottom:<br />

Preview window with fulldome<br />

video.<br />

It is in handling digital image and<br />

sound data that powerdome<br />

brings its special strengths to bear.<br />

Three steps suffice to present digital<br />

data on the dome: loading,<br />

positioning, adapting and pictures,<br />

videos and sound are where<br />

you want them to be. And all this<br />

without entering a single code. Let<br />

a few characteristic examples<br />

demonstrate how this is brought<br />

about.<br />

<strong>Carl</strong> <strong>Zeiss</strong> digital powerdome®Systems<br />

offer solutions for full-dome<br />

projection that involve a variety of<br />

technologies. They cannot, nor are<br />

they meant to, replace an opticalmechanical<br />

planetarium projector.<br />

Although powerdome features the<br />

planetarium functions, no digital<br />

projection technology can compare<br />

with the brilliant sky projected with<br />

a fiber-optic projection machine.<br />

No video projector is capable to<br />

project individual pixels with a<br />

brightness of 1000 lux.<br />

Systems in unison<br />

Therefore, powerdome®Systems<br />

of every variety can be directly<br />

coupled with any of the recent optical-mechanical<br />

projectors made<br />

by <strong>Carl</strong> <strong>Zeiss</strong>, in which case digital<br />

projection consistently follows the<br />

astronomical parameters of optical-mechanical<br />

projection. This<br />

type of coupling goes beyond any<br />

hybrid solution in which two independent<br />

systems merely complement<br />

or replace each other. The<br />

integrated control concept renders<br />

an independent digital planetarium<br />

for classical presentations of<br />

the earth’s night-time sky superfluous.<br />

Rather, the digital planetarium<br />

functions of powerdome<br />

expand the presentation capabilities<br />

of the optical-mechanical projector,<br />

which can bring to bear its<br />

undisputed advantages at the<br />

same time. For user to employ one<br />

or the other of the two projection<br />

systems makes no difference: the<br />

integrated control ensures that<br />

both systems always work in unison.<br />

Whoever wants to use powerdome<br />

for presentations without<br />

an optical-mechanical projector<br />

can use the control panel and<br />

control program of the latter, with<br />

all its astronomical functions, to<br />

control the video projection system<br />

instead of the classical projector.<br />

The advantage of this solution<br />

is obvious: The video system<br />

is operated by the principle<br />

of the classical planetarium. Live<br />

operation through rotary controls<br />

and pushbuttons is just as simple<br />

as automatic or semi-automatic<br />

reproduction. Manual operations<br />

can be saved, edited and reproduced.<br />

It is no surprise, then, that the<br />

current version of the <strong>Carl</strong> <strong>Zeiss</strong><br />

powerdome software is primarily<br />

focused on the easy handling of<br />

digital data to present.<br />

Full-dome video<br />

The simplest case of application is<br />

the playback of a full-dome video.<br />

Only two files are required: the<br />

video file for projection, and the<br />

sound.<br />

ShowManager, the Windows ® -<br />

based user interface of powerdome,<br />

allows users to manage,<br />

schedule and adapt all data for a<br />

dome presentation. A Resources<br />

window is used for data import.<br />

As the show elements are categorized,<br />

the user will not get lost even<br />

in case of complex shows comprising<br />

many files. The video file is<br />

loaded to the video resource window,<br />

and the sound file to the audio<br />

one. Right next to the Resources<br />

window, ShowManager<br />

offers a Preview window. Videos<br />

and still images can be played<br />

back and displayed, respectively,<br />

and audio sources listened to. No<br />

change to another program is required,<br />

should a file name fail to<br />

reveal whether this is the desired<br />

resource.<br />

The third window arranged in<br />

a row with the other two is the<br />

Properties window, in which all<br />

relevant parameters of a file are<br />

displayed automatically and can<br />

be modified as appropriate for the<br />

file type. Parameters for full-dome<br />

videos include running time, resolution,<br />

gamma, and mapping. Run-<br />

8 Innovation Special Planetariums 7, <strong>Carl</strong> <strong>Zeiss</strong>, 2008


Product Applications<br />

ning time and resolution are defined<br />

by the video, i.e. fixed,<br />

whereas the other two parameters<br />

can be adapted. The gamma parameter<br />

allows you to adjust the<br />

brightness of the video, while<br />

dome mapping is a prerequisite for<br />

full-dome videos; other settings<br />

can be made for plane (classical)<br />

videos or panorama presentations.<br />

In most cases, though, no changes<br />

need to be made to the properties<br />

of the source data files.<br />

Once video and audio files have<br />

been loaded to the powerdome®<br />

ShowManager, the second step is<br />

positioning them. For full-dome<br />

video, positioning merely means<br />

fixing the start time with the<br />

powerdome Timeline Editor, in<br />

which you can create chapters and<br />

levels with several tracks. For the<br />

application described, one chapter<br />

and one level with two tracks (for<br />

video and audio) are sufficient.<br />

Use the mouse to drag the files<br />

from the Resources window and<br />

drop them on the respective track.<br />

Powerdome automatically creates<br />

a show element characterizing the<br />

respective resource and its running<br />

time. The show elements can<br />

be shifted to the start of the<br />

timeline or to any other start times<br />

with the mouse. For precise positioning,<br />

the start times can be entered<br />

digitally in the Properties<br />

window. Once positioning is completed,<br />

the full-dome video is<br />

ready to be shown.<br />

Before that, however, it is possible<br />

to adapt (animate) the show<br />

elements with certain parameters<br />

if necessary or desired. For example,<br />

you can fade in the video<br />

or shorten the sound. Such processes<br />

are done conveniently in<br />

the powerdome Animation Editor,<br />

which provides all parameters<br />

that are variable for the resource<br />

selected (video, still image,<br />

sound, projector control, dome<br />

lighting, etc.). For fade-in, use<br />

the “Opacity” parameter. Setting<br />

it to “0” at the start of the video<br />

makes the video transparent, i.e.<br />

invisible. The opacity setting “1”<br />

in another key frame at the 2 sec<br />

time position causes the video to<br />

be faded in from 0 to 100 percent<br />

within two seconds. By the same<br />

principle, the user can set positions,<br />

motions, changes of size<br />

and color, or other parameters.<br />

Here again, no codes have to be<br />

programmed; powerdome saves<br />

the data from the graphic Animation<br />

Editor in the show file. This<br />

results in another advantage for<br />

the user: In powerdome, all control<br />

cues of a show are contained<br />

in a single show file. If parameters<br />

of a kind are to be varied for all<br />

relevant show elements, an text<br />

editor can accomplish this within<br />

seconds by means of the Findand-Replace<br />

function.<br />

With the animations completed,<br />

save the show file. The full-dome<br />

video is now ready for playback.<br />

Typical diagram of the<br />

projection systems of a<br />

consisting of panorama, allsky,<br />

video and multi-image<br />

slide projectors. For each<br />

projection system, a separate<br />

track is created in<br />

powerdome.<br />

(Source: <strong>Zeiss</strong> Planetarium,<br />

Bochum/Germany)<br />

One of the frequently asked questions<br />

is whether a full-dome video<br />

upgrade spells doom for older,<br />

“classical” planetarium shows, or<br />

whether they can be run on powerdome<br />

as well.<br />

The plain answer is, they can.<br />

Powerdome is compatible with<br />

your “old” shows or with classical<br />

planetarium shows procured<br />

from other suppliers, provided that<br />

all contents are available in digital<br />

form. This means that slides have<br />

to be scanned, videos transformed<br />

into digital formats, and music and<br />

narration converted into an audio<br />

file readable by the computer. In<br />

very many cases, the slide images<br />

were exposed on film from originally<br />

digital source data, which<br />

should be available. Likewise, videos<br />

are computer-readable files, as<br />

a rule. Planetarium shows produced<br />

today are almost always<br />

supplied in digital form on DVDs.<br />

With the powerdome®Show-<br />

Manager you can bring your classical<br />

shows into the digital age<br />

without much effort.<br />

Usually, every classical planetarium<br />

has a diagram of its projection<br />

systems, which shows the<br />

type of projections (slides, panorama,<br />

all-sky, etc.) and their image<br />

positions on the dome. Planetarium<br />

show productions offered<br />

for sale also assume more or less<br />

standardized projection facilities.<br />

You reproduce these projection<br />

systems in powerdome.<br />

First, create two levels: a dome<br />

level for all-sky and full-dome videos<br />

and a planar level for plane<br />

slides and videos. Create a number<br />

of tracks that correspond to<br />

your classical projection systems,<br />

e.g., two for the panorama A and<br />

B with edge blending. Assign different<br />

“object distances” for these<br />

levels by varying the respective “Z<br />

parameters”. This arranges allskies<br />

in the background, slides in<br />

front, and panoramas in between.<br />

In case of simultaneous projection,<br />

slides will then partially occlude<br />

the panorama, which in turn<br />

will occlude the all-sky. For this<br />

occlusion, the picture subjects<br />

need to be keyed, as a rule, and to<br />

be saved with a transparent background<br />

(alpha channel).<br />

Unlike slide projectors, powerdome<br />

does not limit the positions<br />

and sizes of slides. Nevertheless,<br />

it makes sense first to retain the<br />

original slide positions in powerdome<br />

and modify them later, if<br />

necessary. Assign each slide projector<br />

the respective position coordinates<br />

and image size on the<br />

dome in terms of powerdome coordinates.<br />

For this, powerdome<br />

uses no other parameters than the<br />

horizontal coordinates of azimuth<br />

and height (longitude/latitude)<br />

and the data for image width and<br />

image height in degrees. Create a<br />

separate track for each slide projector,<br />

and powerdome lets you always<br />

keep sight of everything.<br />

Once you have loaded all files<br />

needed to the Resources window,<br />

drag the elements to the desired<br />

start time position on the track assigned<br />

for them. Set the duration<br />

of the each element, and animate<br />

fade-ins and fade-outs as desired.<br />

With powerdome you can direct<br />

movements all across the dome.<br />

The essential steps of transferring<br />

an analog show to powerdome<br />

have now been completed.<br />

Saving the show loads all show<br />

elements to the main memory of<br />

powerdome, from which they are<br />

read out to the projectors in real<br />

time. No further operator interference<br />

is necessary.<br />

Show chapters<br />

“This Month’s <strong>Sky</strong>”, “The Stars<br />

Tonight”, “Stars Live” or the like<br />

are the titles of shows presenting<br />

the current aspect of the local sky<br />

in a planetarium. Powerdome<br />

turns such demonstrations into<br />

multimedia highlights, too. The<br />

starry sky is the domain of the<br />

optical-mechanical projector. By<br />

means of powerdome you emphasize<br />

particular objects in the sky,<br />

show computer animations that<br />

illustrate the physics behind the<br />

phenomena, or add recent sky<br />

photographs from the Internet. A<br />

potential scenario might look like<br />

this:<br />

Divide your live presentation<br />

into several chapters, in which,<br />

proceeding from the current day’s<br />

night sky, you present typical celestial<br />

bodies and illustrate events<br />

of topical interest. Create these<br />

chapters in powerdome. A first<br />

chapter, for example, may identify<br />

the positions of conspicuous<br />

immediately change to the next<br />

want to stop or begin a show at a<br />

particular point (pauses) or jump<br />

to preset show segments.<br />

Basics<br />

Volkmar Schorcht<br />

The Basics of Fulldome<br />

For quite some time,<br />

full-dome has been the<br />

number one topic in<br />

the planetarium world.<br />

Digital full-dome projection<br />

is entering more<br />

and more planetariums<br />

and has a decisive influence<br />

on their future.<br />

Whoever has not<br />

gone into the matter<br />

yet will find a concise<br />

introduction to this<br />

medium below.<br />

The full-dome<br />

medium<br />

From the classical planetarium<br />

with its optical-mechanical projection,<br />

full-dome differs by three essential<br />

characteristics:<br />

• Per se, no restriction to astronomical<br />

contents.<br />

• Digital technologies employed<br />

for the entire process – from<br />

production to projection.<br />

• Potential of standardization and<br />

networking.<br />

For planetarium visitors, the<br />

change is visible by a higher degree<br />

of being involved – the closed<br />

image projection surrounds them<br />

on all sides. They experience a<br />

spherical screen live with the dynamics<br />

and the diversity of subjects<br />

known from modern media,<br />

but with audiovisual impressions<br />

to be found only in a full-dome<br />

theater.<br />

Full-dome is a new medium. It<br />

is based on existing media such as<br />

planetarium, virtual reality and<br />

movie, but raises them to a new<br />

level. The insistence on astronomical<br />

contents in most full-dome theaters<br />

results from their origins as<br />

planetariums and somehow contradicts<br />

their potential of full-dome<br />

presentation. Present endeavors to<br />

establish a special full-dome community<br />

(IMERSA = Immersive Media,<br />

Entertainment, Research, Science<br />

& Arts) is only a consequence<br />

of this development.<br />

More than half of the domes<br />

with full-dome projection facilities<br />

are mobile and small planetariums<br />

that essentially use the digital planetarium<br />

component without playing<br />

full-dome videos. The others,<br />

with a few exceptions, also have a<br />

primarily astronomical orientation,<br />

but offer full-dome shows with<br />

completely different subjects in<br />

addition to the typical planetarium<br />

shows. There is no telling yet<br />

whether and how much there will<br />

Fig. 1: Complete dome projection<br />

be a separation some day of dome<br />

theaters with specific planetarium<br />

functions and full-dome theaters<br />

without any planetarium context.<br />

Full-dome<br />

technology<br />

Full-dome requires the projection<br />

of a video image onto a spherical<br />

dome. There are three kinds:<br />

• Complete projection – the image<br />

extends over 360 degrees<br />

in azimuth and down to the<br />

dome horizon, approx. 180 degrees<br />

(Fig. 1);<br />

• Truncated projection – the<br />

“rear” part of the projection is<br />

truncated. The format is restricted<br />

to systems having fisheye<br />

projection lenses (see below),<br />

and is based on a compromise<br />

between full-dome projection<br />

and efficient utilization of<br />

the number of pixels on a rectangular<br />

imager (Fig. 2);<br />

• Panorama projection – using a<br />

segment of about 220° in azimuth<br />

and 120° in height. The<br />

format is applied only for multichannel<br />

projections. It is a costsaving<br />

compromise that is rarely<br />

ever used.<br />

<strong>Carl</strong> <strong>Zeiss</strong> always configures its<br />

powerdome®Systems for projection<br />

onto the complete dome.<br />

For full-dome video projection,<br />

three different techniques are employed:<br />

Fig. 2: Truncated dome projection<br />

Fig. 3: The five partial images of a<br />

SPACEGATE projection differentiated<br />

(image assembly).<br />

• Multichannel projection – several<br />

partial images are assembled<br />

to form a complete picture. The<br />

projectors may be placed at the<br />

periphery or in the middle of the<br />

dome (next to the planetarium<br />

projector). The multichannel solution<br />

provides a maximum of<br />

flexibility and the best possible<br />

quality (Fig. 3).<br />

• Fish-eye projection – a projector<br />

arranged in the middle projects<br />

a full-dome image by means of a<br />

fish-eye lens. Because of the limited<br />

resolution and image quality,<br />

this is only recommendable<br />

for small and mobile domes.<br />

• Single channel projection via a<br />

convex mirror at the dome periphery.<br />

Inexpensive method of<br />

lesser quality.<br />

tion. They permit high-quality solutions<br />

for all projects. Partial images<br />

are assembled by blending<br />

their edges. Blended edges are a<br />

critical factor for image quality.<br />

Therefore, <strong>Carl</strong> <strong>Zeiss</strong> has taken<br />

many technical measures to successfully<br />

suppress edge visibility.<br />

The number of projectors comprising<br />

a full-dome system depends<br />

on several factors:<br />

• The desired resolution and<br />

brightness<br />

• Placement of the projectors, depending<br />

on the theater layout<br />

and available space<br />

• Consideration of obstructions<br />

by the planetarium projector<br />

• Aspect ratio of the imager<br />

• Availability of projection lenses<br />

The above illustrations are examples<br />

showing the image channels<br />

for three different projector<br />

systems (Fig. 4).<br />

Full-dome contents<br />

The equipment is but a means to<br />

an end. What is decisive for the visitor<br />

is what the projection equipment<br />

shows, what story is narrated<br />

or how the various media interact<br />

in a live presentation. The fulldome<br />

technology permits two approaches<br />

to content presentation:<br />

1. Presentation of pre-produced or<br />

pre-rendered contents<br />

2. Live presentation by means of<br />

data visualized in real-time.<br />

The powerdome®Systems allow<br />

both versions to be combined.<br />

With pre-produced contents it<br />

is sufficient to start a show, which<br />

then runs off without further interaction.<br />

Such shows may consist<br />

of full-dome videos, scenes,<br />

or complete shows assembled<br />

from individual show elements.<br />

Live presentations require suitable<br />

software for real-time visualization,<br />

such as Uniview. Uniview<br />

comprises the objects of the solar<br />

system and the Milky Way, and<br />

comprehensive data of the extragalactic<br />

space, and allows<br />

seamless navigation within these<br />

spaces. Interaction can be done<br />

via remote control; Internet data<br />

can be integrated live.<br />

It is obvious that pre-produced<br />

contents remain the same from run<br />

to run. A live presentation, even of<br />

the same subject, allows variation<br />

at any time, a fact that is appreciated<br />

by planetarium audiences.<br />

The full-dome format<br />

Fig. 5: Dome master (single frame).<br />

There are no standards for fulldome<br />

projection. Nevertheless,<br />

producers largely stick to uniform<br />

formats.<br />

The dome image has the form<br />

of a hemisphere. Therefore, the<br />

input image format (dome master)<br />

is circular (Fig. 5). In order that it<br />

does not appear compressed on<br />

the dome, like radiuses must correspond<br />

to like height angles. The<br />

bottom edge of the image is projected<br />

in front (“south” for planetariums<br />

on the northern hemisphere).<br />

The bigger the dome, the more<br />

pixels shall the input image have.<br />

For powerdome®Systems, dome<br />

masters with up to 4096x4096 pixel<br />

resolution are suitable. Whereas the<br />

NTSC format with 29.97 frames per<br />

second (fps) was dominating for<br />

some time, 30 fps have become<br />

common meanwhile.<br />

The dome masters are generated<br />

and saved in loss-free formats,<br />

either as Targa files (tga), or (more<br />

and more) in the PNG format,<br />

which is more efficient with regard<br />

to storage.<br />

As an audio format, 5.1 Surround<br />

is gaining ground. Some<br />

theaters use stereo or 7.1 sound<br />

systems, though.<br />

The frame part not used for<br />

image projection can be used<br />

for information.<br />

To produce a full-dome video primarily<br />

means to create 3D animations<br />

and to render them for the<br />

dome format. Alternatively or in<br />

addition, videos taken with a camera<br />

can be used, and so can 2D<br />

video, photo and graphic imagery.<br />

Rendered sequences from Uniview<br />

can also be integrated.<br />

Depending on the quality intended,<br />

a full-dome production<br />

may consume much time and<br />

money. Budgets for shows consisting<br />

completely of high-grade 3D<br />

animations must be assumed to be<br />

higher by one or two orders of<br />

magnitude than those for classical<br />

planetarium shows.<br />

For this reason, full-dome productions<br />

are often licensed. Some<br />

companies such as INTERMEDIA<br />

and Mirage3D specialize in fulldome<br />

productions.<br />

Many planetariums prove,<br />

though, that producing ones own<br />

full-dome shows need not be<br />

dispended with, provided that<br />

technical and staff resources have<br />

been planned for.<br />

On the other hand, Uniview<br />

makes entry into full-dome projection<br />

very easy. This real-time application<br />

does not require pre-production<br />

and is easy to operate.<br />

Uniview can be regarded as a planetarium<br />

projector that is brought<br />

to life by the voice and enthusiasm<br />

of the operator/narrator.<br />

The full-dome<br />

market<br />

Thanks to the digital technology,<br />

full-dome productions are easily<br />

marketable. With shows freely<br />

available on the market, a fulldome<br />

theater can flexibly extend<br />

its spectrum of shows. Last but<br />

not least, budget pooling between<br />

theaters and institutions for the<br />

purpose of joint full-dome show<br />

production is on the advance. <strong>Carl</strong><br />

Applications<br />

Uniview Goes Online<br />

Jan Warnstam<br />

Staffan Klashed<br />

In the last five years, Uniview has evolved and<br />

emerged as the leading visualization tool for<br />

datasets of vastly different scales, from our home<br />

planet to galaxies and quasars, distant in both<br />

time and space. Meanwhile, a parallel evolution<br />

has occured as the Internet has matured from the<br />

early days of static World Wide Web pages to<br />

today’s complex structures of web-based services<br />

and enormous global social networks. To the<br />

Internet user of today, content and knowledge is<br />

always available online somewhere.<br />

We believe that it is time for the digital dome<br />

industry to take this leap into the online world and<br />

we aim to do this by providing the tools to tap into<br />

online sources of both knowledge and content.<br />

Octopus<br />

What do we mean by knowledge in this context?<br />

Knowledge is people, the scientists, and the science<br />

communicators that tell the story about the data and<br />

turn it into information. We know that to tell a story,<br />

nothing beats human contact, and by letting the expert<br />

communicate directly to the audience a unique<br />

level of authenticity is achieved. Even better, the presentation<br />

turns into a dialogue where the audience<br />

has the option of giving comments and asking questions;<br />

thus adapted, the presentation will better suit<br />

their own needs and interests.<br />

In short: by putting real scientific data into the<br />

hands of dome users, and providing tools to bring<br />

forth the significant stories behind that data, we can<br />

create a unique and significant experience for digital<br />

domes. We do this via Uniview Octopus, a new<br />

networking technology that brings live stories from<br />

scientific data creators into the dome. Through Octopus,<br />

scientists and science communicators from<br />

around the world can connect and bring their data<br />

onto that very dome and help audiences around the<br />

world understand the impact of the data presented.<br />

Furthermore, the Uniview Octopus technology<br />

allows multiple scientists to connect to the same<br />

dome, to do joint presentations to public audiences<br />

or even decision-supporting debates and discussions<br />

with policy and decision makers. We believe that<br />

the role of the dome as a scientific outreach tool is<br />

important, and that this networking technology is a<br />

key step in increasing the sense of realness and closeness<br />

to scientific data for dome audiences.<br />

Octopus, together with the general interactivity<br />

of Uniview, adds true interactivity to the digital<br />

dome, bringing the experience to life and making<br />

every session unique.<br />

Geoscope<br />

Now that we have the knowledge, what about<br />

the content? In Geoscope, we set our focus on<br />

the most explored objecs in space; the Earth, the<br />

Moon and Mars, and all the amazing data about<br />

these that is being collected and shared among<br />

online communities. Geoscope supports two technologies<br />

to make this happen – WMS and KML.<br />

WMS, Web Map Services, is a way of downloading<br />

map textures of dynamic resolution,<br />

meaning that as the camera gets closer to the surface<br />

the resolution of the image increases accordingly.<br />

By doing this in a clever way – downloading<br />

and rendering only what is necessary at the<br />

moment – we can handle datasets vastly larger<br />

than what is normally possible – for instance the<br />

Landsat 7 satellite image catalogue which has a<br />

resolution of 15 meters per pixel over the whole<br />

planet.<br />

KML, Keyhole Markup Language,<br />

is an XML-based data format<br />

for vector and raster data;<br />

points, lines, text, images and<br />

placemarks that are all georeferenced,<br />

i.e. referenced to a position<br />

on the Earth. KML is best known<br />

from the Google Earth application,<br />

but it is an open format and, as of<br />

version 2.2, part of the Open Geospatial<br />

Consortium (OGC) implementation<br />

standard. Because of<br />

the connection to Google Earth,<br />

and several other online Earth<br />

browsers, the community for creating<br />

content in KML is very large<br />

and widespread, from amateur enthusiasts<br />

to researchers and GIS<br />

professionals.<br />

The result? Up-to-date exciting<br />

information on your dome, about<br />

planets that touch everybody’s<br />

life. Whether it is climate change<br />

on Greenland, the geography of<br />

the Alps, economy in Asia or the<br />

latest imagery from Mars, there is<br />

a story to be told for every dataset.<br />

And in the end, it is all about stories.<br />

The new Wonder of Jena:<br />

Planetarium with ADLIP<br />

Susann Jacobi<br />

Public Relations Officer<br />

Ernst Abbe Foundation<br />

For more than eight decades, the<br />

<strong>Zeiss</strong> Planetarium has been appreciated<br />

by families as a destination<br />

for day trips, and as an expert<br />

source of news on astronomy and<br />

space travel by hobby astronomers<br />

and friends of the stars. Since October<br />

2006, the listed building has<br />

boasted a special attraction: Within<br />

two weeks, an ADLIP Full-Dome<br />

Projection System based on six<br />

powerful lasers was successfully<br />

installed, an enormous challenge<br />

for the entire team, but first of all<br />

for the engineers of the <strong>Carl</strong> <strong>Zeiss</strong><br />

and Jenoptik corporations.<br />

The conversion concluded a<br />

technology era that began with six<br />

panorama slide projectors and<br />

lasted nearly 30 years. The commissioning<br />

of laser full-dome projection<br />

made all old slide and effect<br />

projectors obsolete. Today, the six<br />

high-power lasers completely govern<br />

the 800 m² dome surface. The<br />

digital age has finally taken possession<br />

of the time-honored building,<br />

offering its audiences a thrilling<br />

symbiosis of history and future.<br />

With this technology leap, the<br />

house has reached another milestone<br />

in its history. Thanks to the<br />

combination of full-dome digital<br />

laser projection and an opticalmechanical<br />

star projector, the Jena<br />

Planetarium is unique in the world.<br />

The UNIVERSARIUM Model VIII<br />

projection machine of 1996 was<br />

upgraded with new control hardware<br />

and operating software. The<br />

expanded range of functions corresponds<br />

to that of a Model IX. The<br />

upgrade not only enhanced the<br />

systems reliability but also added<br />

new presentation capabilities.<br />

Already at the reopening gala<br />

in October 2006, visitors could<br />

choose between two astronomical<br />

shows and a childrens show.<br />

“Exploring the Universe – Probing<br />

the Heavens with Galileo” and<br />

“The ABC of the Stars” are fulldome<br />

shows produced by STERN-<br />

EVENT GmbH, the company operating<br />

the Planetarium, implemented<br />

by INTERMEDIA GmbH in<br />

Klagenfurt, and running with<br />

great success since. The shows are<br />

February 2007 saw the world premiere<br />

of the latest production of<br />

Mirage3D, “Dawn of the Space<br />

Age”. Meanwhile, the number of<br />

full-dome shows has increased to<br />

nine, including “Infinity plus<br />

One”, the worlds first family musical<br />

in full-dome format, commissioned<br />

by the <strong>Zeiss</strong> Planetarium<br />

and starring Reinhard<br />

Lakomy. The Planetarium produced<br />

its own entertaining shows<br />

and, again collaborating with<br />

INTERMEDIA, the full-dome version<br />

of the successful music show<br />

“Queen Heaven”.<br />

A regular feature is “Stars<br />

Live” – live presentations of the<br />

current aspect and events of the<br />

night sky, with UNIVERSARIUM<br />

and ADLIP combining their specific<br />

advantages.<br />

The first FullDome Festival in<br />

March 2007 was a special highlight.<br />

On the initiative of the<br />

Bauhaus University in Weimar,<br />

students of several universities<br />

had taken up the challenge of<br />

the new medium and presented<br />

their full-dome animations and<br />

short films to the public. A first<br />

sequel to the festival in April<br />

2008 demonstrated an amazing<br />

quality leap in full-dome productions.<br />

Many special events add to<br />

the success of Jenas <strong>Zeiss</strong> Planetarium,<br />

not only from the economic<br />

angle. Companies like to<br />

use the exotic atmosphere under<br />

the starlit dome as an exceptional<br />

setting for conferences<br />

and entertainments. The planetarium<br />

seats can be replaced<br />

with tables and chairs for dinner<br />

parties, sufficiently illuminated<br />

by the bright star and laser projections<br />

on the dome; meals and<br />

drinks are provided by the inhouse<br />

“Bauersfeld” restaurant.<br />

A year after the ADLIP installation<br />

– on the first anniversary of<br />

the innovative projection system,<br />

as it were – the Jena <strong>Zeiss</strong> Planetarium<br />

received a federal award:<br />

The initiative “365 Places in the<br />

Country of Ideas” under the patronage<br />

of the German President<br />

Horst Köhler honors institutions<br />

anywhere in Germany for their<br />

innovative spirit and commitment.<br />

Upgrading to a full-dome theater<br />

has been a thorough success.<br />

The roughly 3000 shows and<br />

other events since the Planetarium<br />

was reopened have been<br />

attended by a total of 250,000<br />

people. In the summer of 2008<br />

we expect the 8.5millionth visitor<br />

since the Planetarium’s inauguration<br />

in 1926.<br />

FullDome Festival<br />

Volkmar Schorcht<br />

FullDome Festival in Jena<br />

The successful premiere of a<br />

FullDome Festival at Jena’s <strong>Zeiss</strong><br />

Planetarium in 2007 encouraged<br />

a second edition this year. The<br />

2008 FullDome Festival was held<br />

on April 25th and 26th, comprising<br />

a workshop of all participants<br />

under the <strong>Carl</strong> <strong>Zeiss</strong> factory dome<br />

and a public presentation at the<br />

Jena <strong>Zeiss</strong> Planetarium.<br />

The Jena FullDome Festival is<br />

unique in Europe. In connection<br />

with the installation of a full-dome<br />

laser projection system at Jena’s<br />

<strong>Zeiss</strong> Planetarium, students of media<br />

science at the Bauhaus University<br />

of Weimar, supervised by Micky<br />

Remann, developed a project entitled<br />

“Astronomy & Media Spaces”.<br />

The project experiments with new<br />

contents suitable for the new capabilities<br />

of full-dome projection.<br />

Students at the Offenbach Academy<br />

of Art and Design had already<br />

been among the active participants<br />

of the 1st FullDome Festival, contributing<br />

short films. Further contributions<br />

came from the Kiel University<br />

of Applied Sciences, where<br />

Eduard Thomas directs the Media-<br />

Dome and has supervised fulldome<br />

projects for several years, and<br />

from the Muthesius Academy of<br />

Fine Arts in Kiel.<br />

The FullDome medium is still in its<br />

infancy, but it is growing at a fast<br />

rate, as shown by the imaginative<br />

works sent in for the 2nd FullDome<br />

Festival. The event was focused on<br />

artistic experiments, short films<br />

produced by students, and professional<br />

applications in the fields of<br />

edutainment, museum education,<br />

interactive worlds, music videos<br />

and games, exemplifying a broad<br />

spectrum of prospects that open<br />

up to the growing global FullDome<br />

community and the public. <strong>Carl</strong><br />

<strong>Zeiss</strong> sees a great creative, entertaining<br />

and educational potential<br />

in full-dome projection.<br />

For the first time, <strong>Carl</strong> <strong>Zeiss</strong> Jena<br />

GmbH sponsored the FullDome<br />

Award. The award honored outstanding<br />

festival contributions in<br />

three categories: the Creative<br />

Award for the best idea, the Performance<br />

Award for the best performance,<br />

and the Audience Award.<br />

The Creative and Performance<br />

Awards were decided upon by a<br />

professional jury comprising lecturers,<br />

experts in aesthetics, and the<br />

hosts, whereas the festival visitors<br />

chose the winner of the Audience<br />

Award. The FullDome Award is intended<br />

to acknowledge works by<br />

students that make visible the<br />

chances of the new medium in<br />

imaginative and exemplary ways.<br />

By sponsoring the awards, <strong>Carl</strong><br />

<strong>Zeiss</strong> wants to motivate students<br />

for continued occupation with the<br />

medium of full-dome projection.<br />

On the first day of the festival,<br />

<strong>Carl</strong> <strong>Zeiss</strong> placed its factory dome<br />

at the students and other participants<br />

disposal for a workshop in<br />

which the students presented their<br />

productions and exchanged experience.<br />

The Creative Award was granted<br />

to Thomas Fritzsche and his festival<br />

trailer “The Diver”. This production<br />

creates the illusion that the<br />

festival site (the planetarium) is<br />

filled with water, with a diver starting<br />

the system and the festival. The<br />

jurors liked the idea because its<br />

originality and exciting image direction<br />

are bound to attract people<br />

to the new full-dome medium.<br />

The winners of the Performance<br />

Award, Nico Uthe and Bastian<br />

Böhm, study at the Muthesius<br />

Academy of Fine Arts in Kiel. With<br />

their visualization of „SciaFobia”<br />

(fear of shadows), they turned the<br />

dome into a stage on which twodimensional<br />

figures and objects<br />

and their shadows acted in a virtual<br />

three-dimensional world, in<br />

the style of classical wild chases<br />

and with quotations from film<br />

scores. This production displayed<br />

great practical and dramaturgical<br />

skills from the idea to the finished<br />

product.<br />

Having seen all twenty festival contributions,<br />

the audience in the<br />

filled-to-capacity <strong>Zeiss</strong> Planetarium<br />

chose as its favorite a pleasurable<br />

ballet staged by Thorsten Greiner<br />

of the Offenbach Academy of Art<br />

and Design. The prizewinner used<br />

his own programming to transform<br />

the subject in a completely abstract<br />

way under the apt title of “50%<br />

Illusion”. Using the dome in a truly<br />

innovative way, he made it evident<br />

how much our ways of thinking<br />

and understanding follow set patterns.<br />

The third FullDome Festival<br />

is scheduled to take<br />

place in April 2009. Its<br />

topic will be “Bauhaus and<br />

the Stars”, as a reminiscence<br />

of 90 years of the<br />

Weimar Bauhaus. Interested<br />

parties may directly<br />

contact the <strong>Zeiss</strong> Planetarium<br />

Compared in Saint Louis<br />

When the Mc Donnell Planetarium<br />

in Saint Louis was reopened in<br />

2001 after comprehensive renovation,<br />

its new concept surprised visitors<br />

and planetarium experts alike.<br />

A UNIVERSARIUM Model IX was<br />

put in service under the large 24 m<br />

dome that capped an auditorium<br />

without seats and not bounded<br />

by walls. Thanks to the fiber-optic<br />

system of the ZEISS projector,<br />

though, the projections are not<br />

impaired by the ambient light. (See<br />

Innovation Planetariums Special<br />

No. 4, 2002).<br />

UNIVERSARIUM<br />

Upgrade<br />

<strong>Carl</strong> <strong>Zeiss</strong> regularly carries out<br />

maintenance of the Saint Louis<br />

planetarium projector – the best<br />

precaution to ensure proper operation<br />

for decades. This does not<br />

mean that system electronics and<br />

software are left untouched by<br />

technical advancement. In 2006/<br />

07, <strong>Carl</strong> <strong>Zeiss</strong> created an upgrade<br />

with new hardware components,<br />

which allows direct coupling with<br />

a <strong>Carl</strong> <strong>Zeiss</strong> digital full-dome video<br />

system, adds new presentation<br />

capabilities by the system software<br />

and enhances system reliability.<br />

The upgrade will be installed in<br />

the course of 2008.<br />

Presentation<br />

of Technologies<br />

Contemplating the installation of<br />

a full-dome video projection system,<br />

the management of the Saint<br />

Louis Science Center approached<br />

<strong>Carl</strong> <strong>Zeiss</strong> with the request to<br />

present different projection technologies<br />

on site for comparison.<br />

The large dome of 24 m diameter<br />

and the ambient light reaching<br />

the auditorium from the surrounding<br />

exhibition space poses<br />

a special challenge to digital fulldome<br />

projection. Having accomplished<br />

full-dome installations in<br />

Jena and Valencia, <strong>Carl</strong> <strong>Zeiss</strong> does<br />

have experience with extra-large<br />

domes; nevertheless, the situation<br />

in the Mc Donnell Planetarium<br />

was a tricky one.<br />

Optimum conditions for a temporary<br />

installation and friendly<br />

relations with the management<br />

and staff of the Mc Donnell Planetarium<br />

made it easy for <strong>Carl</strong> <strong>Zeiss</strong><br />

to comply with the request. The<br />

demonstration was staged in February<br />

2008. More than 50 planetarians<br />

from different places in<br />

USA seized the opportunity to<br />

see, compare and assess the three<br />

major projection technologies of-<br />

Projection Technologies<br />

fered by <strong>Carl</strong> <strong>Zeiss</strong> with their advantages<br />

and drawbacks: DLP,<br />

SXRD and Laser Display.<br />

For the perfect organization of<br />

the event, our thanks are due to<br />

Seiler Instruments & Mfg. Company,<br />

the agent for <strong>Carl</strong> <strong>Zeiss</strong> planetariums<br />

on the American market.<br />

The systems<br />

With assistance from Barco,<br />

Sony und Jenoptik/RDE, <strong>Carl</strong> <strong>Zeiss</strong><br />

installed three systems, each of<br />

which covered about half the dome<br />

with projected video imagery. With<br />

powerdome as the image generator,<br />

a 30-minute sequence had<br />

been prepared, which represented<br />

the full spectrum of full-dome applications,<br />

from the digital night<br />

sky to gloriously colorful computer<br />

animations.<br />

ADLIP, the Laser Display Technology,<br />

was particularly impressing by<br />

its pitch-dark background and extremely<br />

high color saturation. The<br />

DLP technology with projectors of<br />

the Galaxy 12HB+ series was considered<br />

the brightest by far. The<br />

participants found that the image<br />

definition perceived was about<br />

equal with all systems. A specific<br />

advantage of Sony’s SXRD technology<br />

is its high resolution. The two-<br />

projector system needs a single<br />

edge-blending zone only. Altogether,<br />

all three video systems<br />

stood the test under the large,<br />

weakly illuminated dome.<br />

Assessment<br />

Assessing the technologies, the<br />

participants set different priorities.<br />

For some, the deciding factor is the<br />

brightness of the projection system,<br />

whereas others go by high contrast<br />

and saturated colors.<br />

The temporary installation also<br />

demonstrated that powerdome allows<br />

different projection technologies<br />

to be used without any problems<br />

and widely differing requirements<br />

to be met. For the image data<br />

in the powerdome®ImageGenerator<br />

it makes no difference which<br />

projection system is employed.<br />

Once the parameters for the projector<br />

configuration have been<br />

changed, the same image data can<br />

be played back on another projection<br />

system. There is no need for<br />

repeated slicing or other conversion<br />

of the video stream. Powerdome<br />

is the ideal platform for all<br />

the solutions demonstrated.<br />

Comments from the <strong>Carl</strong> <strong>Zeiss</strong><br />

demonstration:<br />

• “Only the laser offered sufficient<br />

contrast.”<br />

• “This demonstration favored<br />

the ADLIP. The ADLIP had the<br />

best background blackness<br />

and channel blending.”<br />

• “ADLIP, although lower brightness,<br />

didn’t look less bright.<br />

Color saturation added a lot of<br />

life to the presentation. Could<br />

not see blend region of projectors.”<br />

• “Sony most immersive feel of<br />

the 3. I felt a part of the scene.”<br />

• “I liked the sharpness of the<br />

Sony. I like the idea of integrating<br />

the Universarium with<br />

fulldome because I felt fulldome<br />

starfield was not great<br />

at representing the real sky,<br />

where fulldome does an excellent<br />

job representing planets<br />

and allowing traveling in<br />

space.”<br />

Planetarium in U.S.A.<br />

Sheldon Schafer<br />

Director<br />

Lakeview Planetarium<br />

Lakeview Museum, Peoria<br />

Lakeview Museum’s planetarium<br />

is an astronomical resource serving<br />

all of Central Illinois, staffed<br />

with professionals qualified in<br />

astronomy education and interpretation.<br />

Public programs bring the<br />

wonders of the universe and current<br />

astronomical discoveries to<br />

the residents of Central Illinois utilizing<br />

the latest projection technologies<br />

available.<br />

Plans for the new museum<br />

complex include a planetarium<br />

with a larger dome.<br />

Computer graphic:<br />

Peoria Lakeview-Museum<br />

The Lakeview Museum<br />

Planetarium was the first<br />

component of Lakeview Museum in<br />

Peoria, a city with about 100,000 inhabitants<br />

located in Illinois approx.<br />

200 kilometers southwest of Chicago.<br />

It was opened in 1963, two<br />

years before the Museum was constructed.<br />

A Goto M-1 star projector<br />

was installed in the 10 meter plaster<br />

dome. The initial construction was<br />

funded by a donation from Murray<br />

Baker, with additional assistance<br />

from members of the Peoria Astronomical<br />

Society. Principals among<br />

these were R.P. Van Zandt and Dr.<br />

Ernest Landen.<br />

In 1977 the seating was rearranged<br />

to face one direction, and a<br />

Spitz Model 512 Star Projector was<br />

installed. A computer controlled<br />

special effects system was also installed<br />

built by volunteers from the<br />

Caterpillar Computer Club.<br />

In 1989, through a grant from<br />

the Bielfeldt Foundation, a video<br />

projection system was installed. The<br />

system included three video projectors<br />

and a <strong>Sky</strong>-Skan Spice Control<br />

System.<br />

The planetarium serves about<br />

30,000 visitors per year, including<br />

20,000 students from area schools<br />

and colleges. Nearly 1,000,000 visitors<br />

have been to the planetarium<br />

since it opened in 1963.<br />

New: powerdome<br />

On January 26, 2008 the planetarium<br />

in the Lakeview Museum<br />

in Peoria, USA, reopened its doors<br />

to the public after six weeks of<br />

conversion work equipped with a<br />

powerdome®System from <strong>Carl</strong><br />

<strong>Zeiss</strong>.<br />

The powerdome®System has<br />

not only exceeded our staff’s expectations,<br />

but also those of our<br />

public audience. Their reaction<br />

has been overwhelmingly positive.<br />

Teachers have been similarly<br />

impressed, and can’t wait for their<br />

students to experience the new<br />

system. We are delighted about a<br />

starlit sky ten times brighter than<br />

before and the unequalled precision<br />

of the astronomical presentations.<br />

The projections are much<br />

more crisp and the colors much<br />

more brilliant. The observation of<br />

individual stars’ magnitudes and<br />

the determination of their luminosity<br />

classes can only be done<br />

with a precision optical starfield.<br />

These observations prompt students<br />

in class to discuss stellar<br />

evolution, which is then illustrated<br />

by a full-dome show. Only the<br />

ZEISS powerdome®System has the<br />

versatility to do it all.<br />

<strong>Carl</strong> <strong>Zeiss</strong> installed the SKYMAS-<br />

TER ZKP 4 planetarium projector<br />

and SPACEGATE Quinto in January<br />

2008. The combination of<br />

opto-mechanical and digital projection<br />

offers a wide range of new,<br />

hitherto inconceivable possibilities,<br />

which add diversity to the<br />

program. We expect growing audiences,<br />

and families in particular.<br />

This assumption was confirmed by<br />

the throngs of visitors during the<br />

initial days.<br />

Outlook<br />

Plans are under way now for the<br />

erection of a new, larger and more<br />

attractive museum in the city center,<br />

with a bigger planetarium<br />

dome. The powerdome®Planetarium<br />

is a foretaste of the intended<br />

modernization. The planetarium<br />

equipment will be moved into a<br />

new dome as soon as the foundations<br />

for the new museum are<br />

ready.<br />

Judenburg‘s Star Tower:<br />

a Successful Concept<br />

Judenburg’s city tower was constructed<br />

in the years 1449 – 1509.<br />

In the fall of 2006, a planetarium<br />

equipped with SKYMASTER ZKP 4,<br />

powerdome®SPACEGATE and 65<br />

seats was built into the late medieval<br />

structure. To get to the star<br />

theater situated at a height of<br />

46 m above the tower entrance,<br />

visitors use a glass-walled panorama<br />

elevator running in a glass<br />

well up to a level of 38 m, from<br />

where they walk up 20 steps to<br />

the lookout gallery with the cash<br />

desk and a cafeteria.<br />

The planetarium with its 8.5 m<br />

dome was provided with the most<br />

advanced equipment available for<br />

planetariums of this size: a SKY-<br />

MASTER ZKP 4 and the powerdome®SPACEGATE<br />

Quinto fulldome<br />

video system, both from <strong>Carl</strong><br />

<strong>Zeiss</strong>. Together with the Dolby surround<br />

system, the illumination and<br />

the open auditorium, from which<br />

parts of the ancient masonry are<br />

visible, provide an overall impression<br />

that is without equal in the<br />

planetarium world.<br />

Shows in the Star Tower comprise<br />

two parts: the demonstration<br />

of the current night sky, and<br />

a full-dome video film.<br />

At present, not less than eleven<br />

different full-dome shows are offered,<br />

with themes from astronomy,<br />

biology, history and astronautics.<br />

In addition there are programs<br />

for children and adolescents, and<br />

music shows.<br />

In all out thematic shows we attach<br />

great importance to live<br />

moderation. The operator-cumnarrator<br />

explains the current aspect<br />

of the starry sky by means of<br />

the ZKP 4 and tells, in an entertaining<br />

manner, whatever is<br />

worth knowing about the nakedeye<br />

celestial objects.<br />

For special guests and professional<br />

audiences we run special<br />

shows on astronomical subjects<br />

and specialist lectures making<br />

use of Powerpoint presentation.<br />

Other events include live concerts,<br />

mainly by instrumental soloists.<br />

We also rent the star theater<br />

out for family parties, business<br />

luncheons and the like. To<br />

all such occasions, the starry sky<br />

lends an enchanting touch.<br />

Since recently, our visitors can<br />

use the interactive astronomy<br />

program “Uniview” and an X-Box<br />

controller to travel through the<br />

solar system in real time, to visit<br />

the planets and their moons, to<br />

fly round our Galaxy, and to get<br />

to the boundaries of the observable<br />

universe. The tremendously<br />

impressive visualization and the<br />

flexibility of presentation make<br />

this an exceptional experience,<br />

which our visitors will remember<br />

for a long time and which is liable<br />

to make them come again.<br />

After more than 18 months of<br />

operation and a total attendance<br />

figure of almost 70,000, it is justified<br />

to consider our concept a<br />

great success. This is no reason,<br />

though, for us to rest on our laurels.<br />

We intend to expand our activities<br />

to sites outside the Star<br />

Tower. In 2008 we plan to lay out<br />

planet paths that extend from the<br />

tower radially and lead into<br />

Judenburg’s surroundings. An<br />

observatory on the Brandkogel<br />

mountain at a height of 1760 m<br />

is at the planning stage, same as<br />

a star hotel in the town. For these<br />

and other projects, sponsors, the<br />

local government and the town<br />

councilors have willingly promised<br />

their support – another sign<br />

that we have taken the right path.<br />

The Star Tower, Judenburg’s tallest<br />

structure (76 m) is an attractive<br />

feature of the town not only<br />

by its mere conspicuousness, but<br />

also by its activities. Judenburg<br />

will probably develop into a<br />

widely known meeting place for<br />

(prospective) astronomy fans.<br />

Tenders for designing the building<br />

of nearly 6,000 m² floor space<br />

had been invited from all over Europe;<br />

the contract was awarded<br />

to Askim og Lantto Architects AS.<br />

The planetarium, the chief attraction,<br />

presents itself as a<br />

sphere hovering in a glass palace,<br />

the architectural highlight and<br />

visitors’ center of the Science<br />

Factory, which accommodates exhibitions,<br />

auditoriums, a library,<br />

workshops, a restaurant and a<br />

museum shop. The sphere has<br />

seats for 60 viewers. <strong>Carl</strong> <strong>Zeiss</strong><br />

landed the order for supplying the<br />

entire technical equipment, featuring<br />

a SKYMASTER ZKP 4 planetarium<br />

projector, coupled with<br />

a powerdome®SPACEGATE fulldome<br />

digital projection system.<br />

It is the third European installation<br />

of this most advanced planetarium<br />

solution for small planetarium<br />

domes. The first two installations<br />

are in Judenburg (Austria),<br />

and Lichtenstein nr. Chemnitz<br />

(Germany).<br />

<strong>Carl</strong> <strong>Zeiss</strong> also supplied the projection<br />

dome, the LED dome illumination,<br />

the sound system, a<br />

number of full-dome shows, and<br />

Uniview as an astronomical realtime<br />

software program.<br />

The successful show “Exploring<br />

the Universe – Probing the<br />

Heavens with Galileo” created in<br />

Jena, which combines opticalmechanical<br />

and digital projections<br />

in an intelligent way, will<br />

have its foreign-language debut<br />

in Sandnes. The planetarium’s<br />

program also includes the two<br />

Mirage3D shows “Origins of Life”<br />

and “Dawn of the Space Age” in<br />

Norwegian versions.<br />

The planetarium staff were<br />

thoroughly trained by specialists<br />

of <strong>Carl</strong> <strong>Zeiss</strong>. The training covered<br />

operation and maintenance of the<br />

equipment and was also attended<br />

by members of the Stavanger Astronomical<br />

Society.<br />

Workshop<br />

First powerdome®<br />

Workshop in Jena<br />

Antje Wulff<br />

The first powerdome®System was<br />

delivered by <strong>Carl</strong> <strong>Zeiss</strong> almost two<br />

years ago. Since then, the number<br />

of users of this system has grown<br />

steadily and worldwide – a good<br />

reason for us to enter into an intensive<br />

exchange of experience<br />

with users and testers of powerdome.<br />

In November 2007, <strong>Carl</strong><br />

<strong>Zeiss</strong> invited them to Jena for a<br />

powerdome®Workshop.<br />

The <strong>Carl</strong> <strong>Zeiss</strong> powerdome®System<br />

comprises an image generator<br />

and a platform for combining digital<br />

and analog dome projection.<br />

The emphasis of the workshops<br />

was on training planetarium staff<br />

to compile simple shows themselves.<br />

The workshop started at Jenas<br />

<strong>Zeiss</strong> Planetarium. The 22 participants<br />

saw two in-house productions,<br />

“Exploring the Universe –<br />

Probing the Heavens with Galileo”<br />

and the family musical “Infinity plus<br />

One”, followed by “Dawn of the<br />

Space Age”, a show by Mirage3D.<br />

Planetarium director Jürgen Hellwig<br />

and his assistant Tobias Wiethoff<br />

gave insights into the conversions<br />

involved in upgrading the planetarium<br />

with powerdome®ADLIP,<br />

and into the production of shows<br />

using this tool.<br />

The second day started with detailed<br />

introductions to powerdome<br />

and Uniview, the SCISS planetarium<br />

software for presenting the<br />

universe in 3D. Under the test dome<br />

on the <strong>Carl</strong> <strong>Zeiss</strong> premises, twelve<br />

completely equipped workstations<br />

were available to the participants.<br />

Full-dome producers and experienced<br />

powerdome users reported<br />

about their experiences and gave<br />

useful tips on the production of<br />

full-dome picture content.<br />

On the third day, the participants<br />

practiced what they had learned<br />

the day before, and implemented<br />

their own ideas using powerdome.<br />

They could immediately visualize<br />

the sequences they created on the<br />

factory dome. Discussions with the<br />

powerdome users gave <strong>Carl</strong> <strong>Zeiss</strong><br />

suggestions for further improvements<br />

and extensions.<br />

After work, the workshop participants<br />

relaxed in a bowling contest,<br />

clad in uniform powerdome<br />

jerseys.<br />

We would like to thank all participants<br />

for their keen interest and<br />

many suggestions. The success of<br />

the event and the great demand for<br />

it have prompted us to repeat it,<br />

and so we are looking forward to<br />

the next powerdome®Workshop.<br />

Three New<br />

Star Theaters in Brazil<br />

Luiz Sampaio<br />

Director<br />

Omnis Lux –<br />

Astronomia & Projetos<br />

Culturais, Brazil<br />

Ever since the first <strong>Carl</strong> <strong>Zeiss</strong> planetarium<br />

was installed in Brazil 50<br />

years ago, the number of ZEISS planetariums<br />

there has constantly increased.<br />

In addition to the wellknown<br />

large-dome star theaters in<br />

Rio de Janeiro and São Paulo, a<br />

great many medium- and smalldome<br />

facilities have come into being<br />

that are equipped with <strong>Carl</strong><br />

<strong>Zeiss</strong> projection equipment. Since<br />

1984, Omnis Lux has been the exclusive<br />

and highly successful <strong>Carl</strong><br />

<strong>Zeiss</strong> agent for planetariums in Brazil.<br />

The year 2008 is marked by the<br />

introduction of digital projection<br />

technology. Omnis Lux has landed<br />

several big, demanding projects<br />

centered around the coupling of<br />

optical-mechanical and digital projection:<br />

• The first Brazilian planetarium to<br />

have digital full-dome projection<br />

is under construction in Belo<br />

Horizonte. Equipped with SKY-<br />

MASTER ZKP 4 and powerdome®SPACEGATE,<br />

it is scheduled<br />

to be opened in the second<br />

half of 2008.<br />

• Another system comprising SKY-<br />

MASTER ZKP 4 and powerdome®<br />

SPACEGATE has been sold to Feira<br />

de Santana, the second-largest<br />

city in the State of Bahia. Here,<br />

too, the planetarium is intended<br />

to become operative in 2008.<br />

• A large planetarium is being<br />

built in Santo André near São<br />

Paulo. The 18 m dome will accommodate<br />

the latest planetarium<br />

technology from <strong>Carl</strong><br />

<strong>Zeiss</strong>: A STARMASTER StarBall<br />

and a powerdome®4DOME system<br />

will combine to deliver fantastic<br />

projections.<br />

With these three new projects, <strong>Carl</strong><br />

<strong>Zeiss</strong> remains the leading planetarium<br />

supplier on the Brazilian<br />

market and proves its strong position<br />

in the digital realm.<br />

The Planetarium in Belo Horizonte will be part of the “Science Square” in the city<br />

center, a joint project of the Brazilian federal government, the Federal University and<br />

the company TIM Brasil.<br />

The Planetarium in Feira de Santana will be the heart of the<br />

new cultural park, the city’s prime cultural center.<br />

The architect’s design shows the Planetarium of Santo André at<br />

the heart of the SABINA Education Center, a science park that<br />

will also be devoted to art and technology.<br />

New Projects<br />

Unbroken Trust in<br />

<strong>Carl</strong> <strong>Zeiss</strong> Technology<br />

Our order books are well filled.<br />

The majority of orders are for<br />

combinations of an optical-mechanical<br />

projection machine<br />

with a digital powerdome®System.<br />

We see this as a sign that<br />

our customers have embraced<br />

our concept of combining classical<br />

projection of the star-studded<br />

sky with digital full-dome<br />

projection.<br />

Orders for our new SKY-<br />

MASTER ZKP 4 small-dome planetarium<br />

are absolutely outstanding:<br />

We have booked almost<br />

twice the number of orders expected.<br />

Certainly, the integration<br />

of fiber-optic systems, digital<br />

control of the planet projectors<br />

and direct coupling with our<br />

powerdome®Planetarium are<br />

the decisive reasons for the extremely<br />

great interest in the<br />

ZKP 4.<br />

The demand for large-dome<br />

systems is undiminished, too, as<br />

evidenced by the projects in<br />

Beijing, Nagoya, Boston and<br />

Santo André. The city of Nagoya<br />

is erecting the worlds biggest<br />

planetarium and has ordered a<br />

UNIVERSARIUM Model IX for it.<br />

The first single starball will be<br />

delivered to Santo André: A<br />

STARMASTER SB creates the bright<br />

starry sky, whereas all didactic<br />

projections are generated by the<br />

powerdome®Planetarium.<br />

Grown trust in our competence<br />

in digital full-dome projection<br />

finds expression also in<br />

projects exclusively comprising<br />

full-dome technology, as in Jeju,<br />

South Korea (see front cover).<br />

We can offer customers for our<br />

powerdome®Systems a great<br />

number of full-dome shows. We<br />

have all the capacities needed for<br />

their marketing, source data processing<br />

and providing ready-toplay<br />

“The ABC of the Stars“ is a<br />

basic program for children<br />

and families. It can well be<br />

combined with optical-mechanical<br />

projection of the<br />

sky.<br />

Tim, while watching the<br />

stars together with his<br />

brother Mark and Mark’s<br />

friend Tina, sees a shooting<br />

star and has the wish to fly to<br />

the Moon. Suddenly the children<br />

are beamed to aboard<br />

the spaceship “Observer”.<br />

Once they have overcome<br />

their initial fright, they travel<br />

across the solar system and<br />

visit the planets. They experience<br />

how different the planets<br />

are by nature, land on<br />

Mars and traverse Saturn’s<br />

rings. Then they come perilously<br />

close to the Sun and are<br />

in danger of burning out, but<br />

the space ship manages to escape<br />

and brings the children<br />

to the Moon at last.<br />

“Exploring the Universe” offers<br />

fundamental astronomical<br />

knowledge within a suspense<br />

story. Galileo’s ghost<br />

accompanies us on an excursion<br />

into the depths of space.<br />

His personal life story was<br />

closely intertwined with the<br />

painful realization that our<br />

home planet had lost its position<br />

as center of the universe.<br />

Galileos observations<br />

initiated further research,<br />

which finally led to the Copernican<br />

perspective on the<br />

universe, and to Keplers laws.<br />

In addition to historic discoveries,<br />

the show also presents<br />

the current state of<br />

knowledge on the structure<br />

of our solar system and the<br />

universe. The exciting combination<br />

of classical planetarium<br />

and digital video<br />

projection adds much to the<br />

effect of the show.<br />

“Origins of Life” is about the<br />

fundamental questions of biology<br />

– origin of life, and the<br />

search for extraterrestrial life.<br />

The show informs about the<br />

chemical principles of the<br />

universe, the origin of which<br />

is hidden in the Big Bang,<br />

and illustrates the development<br />

of stars and planetary<br />

systems. It looks into the beginnings<br />

of life on Earth,<br />

touches upon the extinction<br />

of dinosaurs, and deals with<br />

the search for life forms on<br />

other planets.<br />

“Origins of Life” is a fantastic<br />

journey through time<br />

and pays respect of the living<br />

beings inhabiting the<br />

Earth. Presenting many discoveries<br />

made in the recent<br />

past, the show promotes our<br />

Once upon a time, a sea journey<br />

was one of the most hazardous<br />

adventures. Seafarers<br />

cautiously followed the coastlines,<br />

as they might easily lose<br />

their bearings on the open sea.<br />

Fear accompanied them wherever<br />

they sailed – the fear of<br />

plunging over the edge of the<br />

world. Courageous men like<br />

Columbus and Magellan dared<br />

to sail far out across the ocean<br />

and thus proved that the Earth<br />

is not a disk, but a sphere.<br />

Join the voyage to the limit<br />

An endangered reef, a mystery<br />

about the Moon, two fish, and<br />

the adventure of their life.<br />

“Kaluoka’Hina – The Enchanted<br />

Reef” offers a gripping story, is<br />

full of humor, and teaches us in<br />

a playful way to protect our environment.<br />

Kaluoka’Hina, a gloriously colorful<br />

tropical reef, is under a<br />

spell: It is undiscoverable by men.<br />

Kaluoka’Hina’s colorful inhabitants<br />

have thus always lived in<br />

peace, until the volcano erupts,<br />

and the spell is broken. Now it’s<br />

up to Shorty and Jake to restore<br />

the magic of Kaluoka’Hina. Their<br />

tells of touching the moon.<br />

with questioning and dreaming<br />

minds. All of them, and everyone<br />

New Faces in<br />

Customer Service<br />

In February 2008, Robert<br />

Miethe (30) joined the Planetarium<br />

Division as a service<br />

engineer. His primary job is installation<br />

and maintenance of<br />

the planetarium systems. Presently<br />

specializing in the<br />

powerdome®Systems and SKY-<br />

MASTER ZKP 4, his activities will<br />

gradually extend to the divisions<br />

entire product range.<br />

powerdome®<br />

UserGroup online<br />

The number of users of digital<br />

powerdome®Systems from<br />

<strong>Carl</strong> <strong>Zeiss</strong> is growing fast. To<br />

be sure, powerdome is not an<br />

image generator designed<br />

once and for all. The software<br />

with its functionality and its<br />

user interface, as well as the<br />

contents and hardware solutions<br />

are continuously being<br />

advanced. New contents are<br />

not only generated by <strong>Carl</strong><br />

<strong>Zeiss</strong>; users also readily make<br />

selected productions of their<br />

own available to other powerdome<br />

users free of charge –<br />

from simple images to fulldome<br />

video sequences. As the<br />

community of powerdome users<br />

increases, the exchange of<br />

information and experience<br />

becomes more meaningful and<br />

useful.<br />

To support such exchange,<br />

including that of contents, <strong>Carl</strong><br />

<strong>Zeiss</strong> makes its Extranet accessible<br />

to all powerdome users.<br />

The powerdome®UserGroup<br />

established itself at the first<br />

powerdome®Workshop in<br />

November 2007 in Jena. Its<br />

members are not only users of<br />

powerdome®Systems, but<br />

producers of powerdome applications,<br />

and, of course, <strong>Carl</strong><br />

<strong>Zeiss</strong> specialists.<br />

<strong>Carl</strong> <strong>Zeiss</strong> offers to render advice<br />

and support to the User<br />

Group on request, while not<br />

intending to control its development.<br />

The Extranet is meant<br />

as a platform that can be used<br />

by all users and whose contents<br />

are largely developed by<br />

themselves.<br />

Offers to the members of the<br />

UserGroup include, among<br />

others:<br />

• powerdome®Library<br />

with still image, video and<br />

sound databases. The Library<br />

is a platform of exchange<br />

among members.<br />

Users can freely download<br />

contents and make their own<br />

contents available to other<br />

users.<br />

• powerdome®Resources<br />

makes available user-relevant<br />

documents. These include<br />

technical descriptions,<br />

operating instructions, a<br />

glossary, etc., all in PDF format.<br />

• powerdome®Forum<br />

This is a forum of discussing<br />

all questions about powerdome<br />

or related to it, and<br />

finding answers jointly.<br />

• powerdome®UserList<br />

offers a list of powerdome<br />

users for direct contacts<br />

and questions.<br />

Nagoya Erects<br />

Biggest<br />

Planetarium<br />

Since 1962, the Science Center<br />

in Nagoya (Japan) has had<br />

a <strong>Carl</strong> <strong>Zeiss</strong> Model IV planetarium.<br />

After 45 years of<br />

successful educational work,<br />

plans for a grand new building<br />

of the science center are<br />

taking shape in Nagoya.<br />

Again, the planetarium will<br />

be at the heart of the complex,<br />

and with a new dimension<br />

at that: A projection<br />

dome 35 m in diameter will<br />

vault the world’s biggest<br />

planetarium with more than<br />

400 seats.<br />

<strong>Carl</strong> <strong>Zeiss</strong> landed the order<br />

for supplying a Model IX planetarium<br />

projector. By virtue of<br />

its excellent technologies,<br />

<strong>Carl</strong> <strong>Zeiss</strong> prevailed over Japanese<br />

competitors. The press<br />

talked about the “top model<br />

from Germany”.<br />

The impressive quality of<br />

the UNIVERSARIUM’s realistic<br />

starry sky was a decisive<br />

factor for Nagoya. The enormous<br />

dome size selected results<br />

from the fact that the<br />

similarity of the artificial sky<br />

to the natural one increases<br />

with dome size. For the same<br />

reason, Nagoya opted on a<br />

projector that projects the<br />

very number of stars visible<br />

to the human eye in the natural<br />

sky.<br />

The Planetarium in Nagoya<br />

has attracted about 250,000<br />

visitors annually. When the<br />

new building is ready, annual<br />

attendances are expected<br />

to reach a million.<br />

Intended for the education<br />

of young people, the modernized<br />

science center will<br />

feature large exhibition areas<br />

and interactive exhibits, with<br />

the new planetarium being<br />

in the focus of interest. The<br />

vast complex is scheduled for<br />

completion in 2011.<br />

<strong>Carl</strong> <strong>Zeiss</strong> will specially<br />

configure the planetarium<br />

projector for the Nagoya installation.<br />

It will be one of an<br />

international family of large<br />

UNIVERSARIUM projectors in<br />

use in planetariums in New<br />

York, Los Angeles, Rio de<br />

Janeiro, Hamburg, Vienna,<br />

Jakarta, Beijing, Jena and<br />

other places.<br />

Project sketches of the architecture and<br />

the auditorium of the new science<br />

center in Nagoya. A 35 m dome will<br />

make it the world’s biggest planetarium.<br />
