Messier 75 (M 75)

Introduction | Map | My Own Photos | My Own Observations | References

On this page I collect my observations of the globular star cluster M 75 (NGC 6864) in the constellation Sagittarius.

Introduction

The globular star cluster M 75 is located in the constellation Sagittarius and is, according to Stoyan, following M 54, the farthest away globular star cluster in Messier's catalogue, which explains its low brightness and size.
