Description

Sharpless 115 is a faint emission nebula around 7,500 light years away in the constellation of Cygnus. The nebula is ionized by stars in the open cluster Berkeley 90 (from the Berkeley Open Cluster Catalogue, 1958). The cluster, which is embedded in Sh 115, is thought to be only 100 million years old.

To the left of centre, just below the midline, is the planetary nebula Abell 71. I have been unable to find any distance estimates for Abell 71.

Sharpless 115 was photographed between 30 August and 24 September 2019 from a remote imaging rig that is jointly owned and operated by Barry Wilson and me.
