Well at 5hrs 40mins worth of 5 minute subs I'm ready to call it a day on this one. I am overall happy with it but I lost plenty of data to a declination guiding issue. The telescope is on the work bench right now being shortened to accommodate the adaptive optics unit I have here for it. Hopefully that will help to address my problems.
Funnily enough, no darks for this one. When I calibrate this image with darks from my library I seem to loose data and gain noise. Something is amiss there I think.
A good result Alex. Darks need to be redone every now and then.
Perhaps you can try using adaptive dark with a good bias. CCDstack will do that. It can be more accurate at times.
Ideally darks match the lights in duration and temperature.
I have a dark library but it was all recorded during summer when the cooling was pumping at 85% to reach -15c. Now imaging at -15c with only 48% cooling power. I wonder if that extra power consumption of the tec introduced electrical noise? I will recapture a series of darks tonight and see how it goes.
