There's the age-old SNR trade off with exposure length on these cameras, even with the relatively low read noise. I think if you stay away from extremes and consider your target when selecting exposure lengths you'll do fine.

I built up a dark library with 1, 5, 30, 180 and 300s exposures for the two gain settings I use (53 and 111) and don't deviate from those. I basically only use two... 300s for imaging and 1s for flat darks.
Thanks Lee. Yes I think I got away with 10 minutes here but a lot of the stars are saturated so 5 minutes makes more sense.

Keeping it simple is a key to success in this game. It can get too complicated very easily and less fun as a result.

Greg.
