Messier 92 or NGC 6341 is the "other" Globlular cluster in Hercules. M92 is one of the brighter globular clusters in the northern hemisphere, but it is often overlooked by amateur astronomers because of its proximity to the even more /better M13. M92 is visible to the naked eye under very good conditions (not in NJ). Among the Milky Way population of globular clusters, Messier 92 is among the brighter clusters in terms of absolute magnitude. It is also one of the oldest clusters (estimated age being 14.2 +/- 1.2 Billion Years.
