DescriptionMessier recorded this discovery (#11) two weeks after M21 on June 20, 1764: it describes both a cluster "on the parallel of the proceeding [M23]" and "a large nebulosity in which there are many stars of different magnitudes: the light which is spread throughout this cluster is divided into several parts". <--> We're viewing portions of the Milky Way star cloud as it is alternately framed and obscured by dark nebulae (dust). In many ways, it's the most dramatic demonstration of the immensity of the Milky Way and for me personally is a favorite object. While Messier continues his movement to higher declination's, from the Catskill region, I can get very little time on this target given how low it is on my horizon. When I started this capture the left side was actually in the trees. In the gallery you'll see an earlier image centered on the small, open cluster NGC 6603 taken with my EdgeHD.
