NGC6940 and the Veil nebular complex.  This photo was taken on august 2020 by using a filter modified Canon Eos 400D with EF 135 mm lens at f/2.8t on Astrotrac. The photo is the sum of 30 frames, each of 2 minutes. NGC6940 is a rich and large open cluster that lies approximately 2,500 light-years away and near the border between Vulpecula and Cygnus. The Veil nebular complex is what remains visible of a Milky Way star exploded about 9,000 years ago. The Veil nebular complex is physically huge, however, and even though it lies about 1,400 light-years distant, it covers over five times the size of the full Moon. The bright star on the left is Epsilon Cygni.
