Hi
This seldom imaged nebula is fairly close to NGC7000 and isn't often done in narrow band due to the very weak OIII and SII signals. The OIII is so weak that it doesn't show up on the raw frames or the stacked master frame until it is stretched quite considerably. This was taken over 3 nights and comprises of 17x10 minutes Ha and 20x10 minutes each of OIII and SII. As mentioned the OIII in particular needed a lot of pushing in the processing so some of the stars may have a bluish tinge as a result. It was taken with the Televue NP127is/FLI astrograph that I'm testing on my Paramount ME. The OIII and SII data was shot during the recent "Super" full moon.

Thanks for looking
