The Western Veil Nebula and Pickering’s Triangle

If Cygnus would stay in the sky all year, I don’t know if I could exhaust all of its imaging possibilities.  This is the Western Veil Nebula, NGC 6960 and Pickering’s Triangle (bottom left). Both are remnants of a supernova from about 5,000 years ago that also includes the beautiful NGC 6888 (not shown) among others.  This nebula is surprisingly bright in all three major narrowband lines, H-alpha, S-II, and O-III, which meant that I could capture a reasonable amount of data in a single night.
