M24 (no NGC No.) is a bright "star cloud" at the center of Milky Way in Sagittarius.
Strictly speaking, this object is not nebula nor star clusters, but Messier had registered this in the catalogue as a cluster with a size of 1.5 degree.
This naked eye cloud perhaps reminds you of a horse face turning upper left. Two dark nebulae in the cloud look like the eyes of horse are Barnard 92 (west side), and Barnard 93 (east side). And you can see a small reddish diffused nebula of IC1283 at the horse's throat.
