Background subtraction<br />
Method 1:<br />
- Run SExtractor, find sources<br />
- Mask them<br />
- Determine background on masked image on local grid<br />
- Remove it<br />
- Works fine on most fields<br />
Method 2:<br />
- Use 'I'wii background subtraction<br />
- better <strong>for</strong> nebulae <strong>and</strong> crowded fields<br />
