Globular Cluster Index Globular Cluster Images Globular cluster are a swarm of stars rotating about a common center of gravity. Some, such as M-80 are very compact and dense. Others such as M-4 are much more diffuse and spread out. A quick scan of the thumbnail images below will show how varied they can be.
Many clusters are relatively bright and easy to see and image in a small amateur scope.
The chart above shows distribution of Globular Clusters brighter than magnitude 14 in terms of right ascension and declination. Most of them are below the equator, so observers in the southern hemisphere are favored. Click here for a table that list of the brighter ones.
