To be clear my video is ONLY valid for COOLED astrophotography cameras WITHOUT Amp Glow!! It also assumes good dithering to deal with hot pixels!! Also, yes I have compared with and without, and I can't see any difference.

Also ERRATUM! When comparing the dark current I shouldn't have squared it because the dark current is the mean rather than the standard dev! So for -5C, we'd have sqrt(0.36 + 1.4 * 1.4) = 1.52!!
