Pictured is a portion of the Eastern Veil Nebula, NGC 6992, in Cygnus, which was discovered by William Herschel in 1784. The Veil Nebula is the result of a supernova explosion about 15,000 years ago and is approximately 2,500 light-years away. This bicolor narrowband image was taken through a Hydrogen-alpha filter and an Oxygen[III] filter, with the Red channel assigned to H-alpha, Green channel assigned to O[III], and the Blue channel assigned to 90% O[III]. The image was a total of 8 hrs 20 min exposure.
