I have taken dark frames before of course, but with cameras of plenty of amp glow I don't seem to be able to calibrate the glow out completely, or the darks over compensate during live stacking and I see a purplish /brownish outline of the amp glow on the right.
How do you guy take the darks?
How many darks do you usually take? I have tried 10, 20, 30, I'm not sure what's the magic number or if there is any benefit taking even more?
I assume you know already what exposure and gain you gonna use or already have an extensive library of darks for all combos of exposure+gain+offset?
I also try using just the flat with the dark flat combination in sharpcap, but that won't help with amp glow.
