The Veil Nebula, is part of the Cygnus Loop. Other parts of the loop are visible in this image including the 'Eastern Veil' (to the left), the 'Western Veil' or 'Witch's Broom Nebula'to the right, and Pickering's Triangular Wisp in the center. It 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 ~3x3 degrees; about 6 times the diameter or 36 times the area of a full moon. The distance to the nebula is not precisely known, with estimates ranging from 1,400 to 2,600 light-years. It was discovered on 1784 September 5 by William Herschel. This image was taken August 14-19. It is a total of 8 hours of exposure, 5 hours of h-alpha and 3 hours of color data. Telescope is my Takahashi FSQ-106 and camera is my SBIG STL-11000.
