Description:

A very bright globular cluster with a very high number of separated star members. It's core brightens up very quickly. An interesting feature is a small bright stripe, built up by stars that cannot be separated with the eye. The background is grainy even far away from the core, and it is obvious that many of the bright field stars belong to the cluster gravitationally.
