Description

Although I usually shoot NGC6946 each year, I decided to keep 2019's version because I haven't posted anything in a while and I may not collect any subs this year. This version has about two hours of data per LRGB channel and another three hours for the Ha. I played around with saturation more than usual, so the colors are a bit bright and the background is bordering on clipped.
