I just purchased a ZWO ASI294MC Pro Cooled camera a month or so ago...I seem to be having a problem getting good dark frames...They are all coming out gray, not black...
With lens cover on, mounted to the scope, or unmounted, still not dark...I have the camera in a dark closet now doing some 3 minute exposures, same thing gray.
Anyone can assist I would appreciate any and all tips...May be the software, just a thought...I'm using APT to take these...
Thanks,
Rodney
