On this page I collect my observations of the open star cluster M 23 in the constellation Sagittarius.

 

Introduction

The open star cluster M 23 is located in the constellation Sagittarius and is, according to Stoyan, the most Western object of the most prominent objects in Sagittarius and therefore often overlooked.

Find/Identify

Find: M 23 is located to the West (to the right) of M 25, M 24, M 17, and M 18 in a region with few stars. It is also located Northwest of M 21, M 20, and M 8.

Identify: There is a brighter star to the right of the open cluster M 23, which helped me to identify it:

M 23 in constellation Sagittarius and perhaps the star right next to it...
