Veil Nebula
© 2026 Matt Anderson

The Veil Nebula comprises the visible portion of the Cygnus Loop, a supernova remnant found in the constellation Cygnus. It lies about 2,400 light-years from Earth. The progenitor star is estimated to be 12 to 20 times more massive than our Sun and exploded between 15,000 and 25,000 years ago.

This image was created using an RGB palette into which I blended some narrowband Oiii data to bring out more of the blue colors. Some of the interstellar dust around the nebula can be seen on the right. Data were captured using a RedCat 71 and processed in PixInsight. The total aggregation time was approximately 8.3 hours.
