NGC 6960

NGC 6960, also known as the Witch's Broom Nebula, Filamentary Nebula, Caldwell 34, and the Western Veil Nebula, is a filamentary supernova remnant in the constellation Cygnus, discovered in 1784. It's the western arc of the larger Veil Nebula (Cygnus Loop), an expanding shell of gas from a star that exploded roughly 8,000 years ago, featuring delicate, ionized filaments spanning 70 arcminutes.  Its apparent magnitude is 7.0 and the distance from Earth is approximately 2,000 light-years.
