The Veil Nebula is a large supernova remnant in the constellation Cygnus. The supernova which created the nebula occured between 5,000 and 8,000 years ago, and the remnant has since expanded to cover an area of approximately 3 degrees. Estimations for its distance range from 1,400 to 2,600 light years. The brightest sections, designated NGC 6992 and NGC 6995, form the eastern part of the main loop. It features a filamentary structure which is visible in big telescopes and in this photograph. When higly resolved, some parts appear to be rope-like filaments, caused by thin shock waves viewed edge-on. This rendition is a combination of RGB and Ha & OIII narrowband.
