I recently set up a permanent setup, which means I've also found time to finally characterize my camera. Qualitatively, my raw frames look very good; so much so that dark subtraction and flat fielding can have little effect. So, I was pleasantly surprised to discover just how quiet this particular camera is. The read noise is 6.2 e- rms and the dark current rate at -30°C is 2.6 e-/pix/hour(!) with an excellent doubling rate of 4.80°C (meaning, a smaller temperature drop than the usual 6°C rule of thumb will result in a halving of the dark current). I've posted a 1-hour image of M 101 in a Baader B filter over in the astrophotos thread.
