Not too bad for a session from the metro LP zone! Only 96 minutes, but it was enough with these settings to show quite a bit of nebulousity. I used the unity gain setting (11) and that made a big difference in hot pixels and noise. My other shots at a gain of 20 were plagued by hot pixels that SharpCap 3.2 doesn’t seem to be able to deal with very well. I like this much better and there is just as much data buried in there as in the higher gain shots.
Over 4.6 hours of integration with a variety of exposures including 3 min, 2 min and 30 sec sub-images. All were taken with a QHY183c camera at -20C or -15C cooling, an Optolong L-eNhance filter and a Televue TV-85 at F/5.6.
