Another supernova remnant in constellation Cygnus. The progenitor star exploded about 30000 years ago in distance of about 2600 – 3000 light years and the expelled outer shells of the star span today an area in the sky with an diameter of 8 times the full moon. So what you see here is just the southern part of the nebula.
