Terry et al,

Thanks for that - will try to nail a shot with the histogram square in the middle.

A related query springs to mind. If I have the picture and I have the flat, is it easy to do the correction processing in Photoshop CS2 (rather than DeepSkyStacker - which always leaves the colours a bit wierd) and what are the steps involved if anyone knows?

Many thanks, this is great,



When you say if your CCD has a MAX count of 32000 - is that the well depth of each pixel? If I am on a Canon 400D with 12 bit A/D converters to I say the pixel depth is 2 ^ 12 = 4096 so aim for 2048 no more and this is revealed in Photoshop CS2 somewhere?
