| 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. Revisited this target as it was included in the September CN EAA challenge. Happy to take another crack at it, because I wanted to emphasize the background stars and dark nebulae as much as the cluster. |
