225 Notable Star Clusters
Star clusters can appear absolutely stunning in even modest telescopes - jewels suspended against the cosmic backdrop. Star clusters, like galaxies and nebulae, are extended objects.

Here is an A-to-Z list of the 225 brightest star clusters of the night sky that can be found using good binoculars or a telescope. All open star clusters and globular star clusters that are brighter than magnitude 15 are listed.
