Greg, I used the ASI1600MM-C for three years and enjoyed it completely. It is a very forgiving astro camera and can do most things pretty well. AMP glow is really only noticeable on long subs, say 300 sec plus, and is easily calibrated out with Darks. For short fast subs, say up to 60 secs Bias alone is often enough. Yes very low noise so you can shoot lots of short subs without drama. It is worth reading through Ray's threads (Shiraz) on exposure tables for this camera for various scope f ratios. Great cooling system, and does not suffer from the gradient problems that the backlit IMX chips suffer from. You can use the 1600 without ever having to shoot Flats, as long as you keep your optics clean. I never shot flats with mine.
Artifacts, well yes, if you get Alnitak in the frame you will get to see the 'reflection', which is caused by the mono Panasonic sensor not having a MC Clear type anti-reflection cover glass. But most owners learn to compensate in composition.
I only sold mine because I was retiring from serious imaging, and didn't want the mono workload any longer.
