The Crescent Nebula NGC6888

This is was my first image of the 2021 season after a long break. It’s the result of two nights of roughly 1hr total for LRGB, 2hrs Ha and 5hrs Oiii. 

I’ve been practicing with methods to combine the images…

LRGB subs were 30sec @ gain 0, Ha and Oiii susb were 120sec @ gain 200. ASi1600mm pro and filter set, scope was the OO250 newt. Even at 30 seconds and 0 gain I still manage to clip some stars.
