The Veil Nebula, also known as the Cygnus Loop or the Witch's Broom Nebula, is a large, relatively faint supernova remnant in the constellation Cygnus. The source supernova exploded some 5,000 to 8,000 years ago, and the remnants have since expanded to cover an area of 3 degrees. The distance to the nebula is not precisely known, with estimates ranging from 1,400 to 2,600 light years. |

This is my first narrowband image and was the "first light" for my Atik 16HR camera. H-Alpha was assigned a red color, OIII is blue and SII is green.
Hint: Try the buttons on the left side below the image to slide through H-Alpha, O3 and S2. |
