M92

Messier 92 is one of the brightest globular clusters in the northern sky, but it is often overlooked by amateur astronomers because of its proximity to the even more spectacular Messier 13. It is visible to the naked eye under very good seeing conditions. Indeed, M92 is among the brightest clusters in terms of absolute magnitude as well as being one of the oldest clusters in the Milky Way.
