The 183 has very low dark current, so typically the shot noise is higher than the dark noise.

So far, I've resisted the temptation to go below gain 50, as below that quantisation noise becomes an issue...but short subs are the order of the day with my f/4 newt.

Thanks Dunk.

I haven't shot with the gain below 50 so I should try it as an experiment on a high dynamic range object and see how it goes. A lot of my uses of astro gear is from use rather than theory. The results are easy to see usually.

Greg.
