Veil Nebula Narrowband
A star exploded 8000 years ago creating this large structure in the constellation Cygnus. Six times wider than the moon, it's invisible to the naked eye, even from a relatively dark location. But imaging with filters that block all but the wavelengths of excited Hydrogen (red) and Oxygen (blue) reveals the broken sphere of gasses still expanding in space.
Tech Stuff: Borg 55FL astrograph/QHY163 mono/Astronomik H-alpha and O3 filters/iOptron CubePro 8200 unguided. Captured with SharpCap 3.2 as 8 minute stacks of 8 second exposures; total integration time in minutes HA X 95; O3 X 180. Processed with PixInsight including Starnet neural network separation of stars and nebula. Captured from my yard in Westchester County, 10 miles north of New York City, September 15-19 2019.
