I have an ASI1600mm Pro and an ASI294mc Pro.
Very happy with the ASI1600mm and getting great results from it at high gain (200) with short subs and fast lenses/scopes on a Star Adventurer.
I'm still struggling a bit with the ASI294. I got improvements by following suggestions for best practice with this camera from a post on Cloudy Nights (see below) but I'm still not 100% happy. I think that light box flats aren't working well with this camera, though they work perfectly well with the ASI1600mm. My next step is to try sky flats and see if that gets acceptable results combined with all the other improvements I have made.
