Here is the end result, flat subtracted.
Is this caused by near full moon light, a dodgy sensor, or bad flats? (flats were all circa 26000 ADU). 10 min exposures, so I am thinking VERY well past sky-limited exposure....
Both targets of the night show similar results. This is screentransfer
Probably typical moon issue - I've never been stupid enough to try full moon RGB before LOLOLOLOL
