Photo description / processing

The star cluster M71 is located in the constellation Sagitta, within the dense region of the Milky Way. In appearance, it resembles the well-known open cluster M11 (the Wild Duck Cluster). However, M71 is actually a globular cluster with low concentration. Taken from a balcony in Kharkiv, a red zone of light pollution.
