Messier 21 (aka. NGC 6531) is an open star cluster located in the Sagittarius constellation. A relatively young cluster that is tightly packed, it is one of the over 100 Deep Sky Objects listed in the Messier Catalog.
At a distance of 4,250 light years from Earth, this group of 57 various magnitude stars all started life together about 4.6 million years ago as part of the Sagittarius OB1 stellar association. What makes this fairly loose collection of stars rather prized is its youth as a cluster, and the variation of age in its stellar members. Main sequence stars are easy enough to distinguish in a group, but low mass stars are a different story when it comes to separating them from older cluster members.
