NGC 6605 is an open cluster located in the constellationSerpens. It was discovered by the BritishastronomerJohn Herschel in 1826.[1]
With a visual magnitude of 6.0,[2] this cluster is visible to the naked eye from a very dark location free of light pollution. Elsewhere, however, the cluster can be observed with small binoculars.[2]
NGC 6605 is located approximately 3.1 degrees southwest ofGamma Scuti, a magnitude 4.67 star in the constellationScutum.
The apparent size of the cluster is 29 arc minutes, which, given the distance of 1144 pc and through simple calculation, equates to an actual size of about 31 light years.
