| Description | Messier is credited with discovering this open cluster, recorded on October 24, 1764, nearly a month after M38 (his 17th so far). He notes: `Cluster of stars near the tail of the Swan; one can see them with an ordinary telescope of 3.5 feet [FL].' <--> As a "cluster" this is one of the least dense in the Messier Catalog. Nebulosity around several of the larger stars provides some interest. |
