Hi Chris
In an effort to get better star colours, I have been experimenting with really short exposure times (less than 10s) and low gain (50 for the ASI1600).
It does work.
So the plan is:
For the stars: Take 100subs @ 10s. Get the darks and bias at the same setting. Integrate these into one image separately.
For the feint stuff.
Do the same for 120s and then 240s.
So we end up with 3 images for the final integration.
