On this page I collect my observations of the open star cluster M 23 (NGC 6494) in the constellation Sagittarius.
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 is often overlooked.

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 star cluster M 23, which helped me to identify it:
M 23 in constellation Sagittarius and perhaps the star right next to it...
