NGC 7000 a piece of the wall in SHO
Photo description / processing
Tried to find a larger "Wall" on our deep-sky hosting, but there are very few of them; probably NGC 7000 is shot entirely with small scopes, and then no one pays much attention to it. And for good reason—so many "Hair" there.
Shot over three nights, one filter per night, as much sky as the weather allowed, so there's little sulfur.
I shot the stars with the SharpStar 13028HNT; decided to try short 12-sec exposures, 150 frames per channel. I actually want to shoot stars at 1 second and stack them on the fly in SharpCap. And in general, I'll need to try shooting galaxies the same way, i.e., shoot them normally in LRGB at about 180 sec per frame, and then shoot the stars with short exposures, totaling about 30 min per channel. The stars of course didn't turn out great, but that's how the Askar shoots, with its large central obstruction—at least there's color, not holes.
