M45, The Pleiades on Jan 14, 2021

M45 – 32×180 sec @ Gain 11, Offset 100, QHY183c at -20C, Baader UHC-S filter, Televue TV-85 at F/5.6.

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.
