On this page I collect my observations of the globular star cluster M 22 in the constellation Sagittarius.

 

Introduction

The globular star cluster M 22 is located in the constellation Sagittarius and, according to Stoyan, has a prominent position. It is the brightest and easiest globular cluster to dissolve into single stars for Central European observers - only M 4 is larger.

Size: 9'/32' (Stoyan/Wikipedia)
Distance: 10,000 light years (Stoyan)
Rating: **** (Stoyan)
