I think ideally I go for about 8-10 hours with that camera on the Honders. That should give quite a strong signal to noise ratio. Widefield potentially shorter.

No doubt you are too. Well done.

The touch of softness is probably focus not exact, windy poorish conditions plus autoguiding could have been better as I need a new TPoint and refined Polar alignment. There is slight drift between subs which I suppose is good for dither but shows PA is a bit off.

Thanks Mike. I also am working on a 25 hour version which is taken over 7 years, 3 scopes and 3 cameras. Its much the same but a bit deeper and more saturated colour.
Greg.
