This dark nebula lies about one -third the distance from Sadr (gamma Cygni) to the Crescent Nebula (NGC 6888). I christened it The Dementor Nebula because its dark, tattered, veil like appearance reminded me of the characters in the Harry Potter films. The photography editor of Astronomy magazine, Michael Bakich, liked the name and published it along with the expected byline, “Expecto Patronum”. Its official designation is LDN 881.

Telescope: Celestron Compustar C14.

Exposures: Ha:R:G:B = 510:90:80:70 = 12 hours 30 minutes total exposure at f/7.5.
