Description

I struggled with this target from the beginning. I had shot with a gain of 100 in the first two sessions with so so seeing and the stars were way too dominant and a bit blown out so I made it a priority to pick the last dark nights I could and to shoot with a gain of zero instead of 100.  I used PSF weight in sub frame selector to ditch the worst subs from the earlier sessions and then used the star mask from just the last lower gain stack using pixel math with the the total starless stack.
