A mixture of 120×30 sec exposures taken with a L-eNhance filter and a mixture of 15, 30 and 1 minute exposures taken with a UHC filter.   About an hour and 30 minutes total.  The 120×30 set was at 30 gain and -20C.

I am starting to like  the 30 gain setting, since it gives the best results with shorter exposures.  Over 40 is too much noise and under 30 it is just too slow.

When the set began there was no matching dark to subtract, so I was using one at gain 20.   I stopped after about 10 shots and took some darks and then restarted shooting.   I’m glad I did since the amp glow was starting to show up bad on the right side of the frame.  The new darks overcame it and the glow averaged out after a while of LiveStacking with ShapCap 3.2.
