I've often seen this comment about no darks (and not just in this thread) and I just don't understand it. If observatories that cool their cameras to -100 deg need to take darks what makes others feel they don't? Taking darks is an important part of the callibration process. They don't just remove the repeatable noise, but also hot pixels, bias charge, shot noise etc.
