Would that i could Peter, even with a gain of 0 on this camera i find i start getting full wells at about 1.5mins on bright targets. The noise that is there is because this is literally just stacked RAW data, no processing applied apart from an auto screen stretch.
Likewise i my master dark only currently has 9 frames at this setting so with more darks and flats i imagine the noise issue will resolve itself.
My real issue is compiling/stacking/preprocessing the data in the first place

I think you'd control the noise better by taking longer subs (say 3-5 minutes)
