Thanks Steve
I've not used any Bias frames since you advised not to with a CMOS a little while ago! And after I posted this thread it occurred to me that you might have already answered this question in your previous thread! So, if you did, thanks for coming back again!
1) APT requires a Flat Frame Plan to have the camera on Av. It then captures frames at 1/25 sec or 1/30 sec and they do vary sometimes during the plan but only ever between these two settings. This then produces a histogram showing the three peaks at different levels but all between the middle and right sections. Should I instead be selecting a shutter speed?
Yes, select a shutter speed. You could let
APT determine the proper exposure time, then, setup a capture plan for Flats using only that exposure time.

2) I've never done flat darks! I'll have to get into that.
APT allows you to setup a plan for
Dark Flats. Just use the exact same exposure time as used for the Flats.

2a) Let DSS do that automatically? Or manually stack just the flat darks in DSS?
3) Ditto
4) Ditto
I think
DSS will do all of this automatically. I haven't used
DSS for some time now, so, I don't remember if there are any special settings required to make it do this.
Best of luck. If you don't mind, would you let me know how this works out?
Cheers,
Steve
