The Cygnus Wall, a portion of the North American Nebula (NGC 7000) in Cygnus. By Abdur Anwar Sept 6
Using ASI1600MM Pro with ZWO LRGBHa filters RGB: 30 mins each L: 74 mins Scope: 8″ f3.9 reflector
Abdur writes: Capturing the Cygnus wall was one of my goals for this year since Cygnus is almost overhead right now. Really happy with how it turned out. I didn’t take any Ha subs for this target as I prefer the more natural colours of RGB. Due to a lot of Ha emissions, the red would overpower everything else with Ha data.
