The true darkness only last three hours per night, but that will do.
I have just recently gotten a S-II filter, I got my astro camera last year, and started with L, R, G, B, Ha, O-III and V-Johnson filters.
So this weekend I shot about 11 hours of S-II on IC1795 and combined with 2 hours of H-alpha and 3,5 hours of O-III from last fall.
My first attempt on S-II, H-alpha, O-III as R, G, B - Hubble Palette.
I have exclusively used Astroart 7, both for accuiring images, auto focusing, stacking and post-processing.
