[QUOTE="Blade Canyon, post: 622028, member: 15302"] Do you want this information to get properly exposed flats? Or do you need to know the exact number because your stacking software asks for it? If your flats supposed to be a unified field just over half of the maximum pixel value, then it seems like you could use the histogram on your camera to know when you've hit the maximum and also to see if you have a good flat at around 51%. That wouldn't tell you the number, but it would get you the flat you need. (Not trying to start a war about whether histograms are linear...) [/QUOTE]
