Witch's Broom Nebula
The Witch's Broom Nebula (NGC 6960) also known as the Western Veil is a very fascinating part of the sky to image. Despite the nebula being relatively bright (about a magnitude 7), its difficult to see with the naked eye. Imaging in Hydrogen Alpha helps bring out a lot of the tendril details.
