On this page I collect my observations of the globular star cluster M 55 (NGC 6809) in the constellation Sagittarius.
The globular star cluster M 55 is located in the constellation Sagittarius and is, according to Stoyan, the easiest globular cluster to resolve following M 4 and M 22 from a southern European location.
