I would like to know how many flats/darks make a decent sample.
I have taken flats ( tshirt ) at 30/60/180secs at LOW, MEDIUN/HIGH with the ASI during the day, cooler on, trying to get close as possible to the lights I have already taken, and camera exactly the same orientation.
Now working on the darks, as I thought, not much use imaging with a near full moon., with same parameters.
Am I wasteing my time in some ways, it takes a lot of time.
Cheers,
Lance

without showing us an image it's hard to tell, if you did not use darks you have amp glow, you only need to do darks once a year if you use the same gain and temperature. It's not a waste of time.
The 294mc has amp glow and it's there as a light in the sides, the moon would give gradients
