I?have?a ZWO ASI1200MM camera. It is a very fine camera, esp for the price. max QE = 70% and read noise is only about 3e- at maximum video gain.
It is very good for lunar planetary but also performs well on DS.? I am experimenting with?it for semi-lucky DS imaging?using sub-exps ranging from?0.2 to 10 sec.?For camera limited exps, it?suffers from the notorious unstable CMOS banding (like all CMOS) and the temperature is unregulated, both of which cause dark frame issues for semi-lucky DS.?But it is workable.? Here are a few examples:
