The Hole in the Cluster

There is some open star clusters in Cygnus.
Joke!
There is whole lot of open clusters in Cygnus! NGC6811 is one of them, pretty large, pretty old (1 billion years), pretty rich (about 1000 stars). And little bit empty inside, so its nickname is “Hole in the cluster”.
Pictured from my backyard with Moon present. 3h total exposure with RGB filters and usual stuff – 130mm triplet and Atik 383 camera.
