Photo description / processing

Messier 92 (also known M 92, or NGC 6341) is a globular cluster of stars in the northern constellation of Hercules. It was discovered by Johann Elert Bode in 1777, then published in the Jahrbuch during 1779. It was inadvertently rediscovered by Charles Messier in 1781 and added as the 92nd entry in his catalogue. It is about 26,700 light-years away from the Solar System. It is one of the brighter of its sort in apparent magnitude in the northern hemisphere and in its absolute magnitude in the galaxy, but it is often overlooked by amateur astronomers due to angular proximity to bright cluster Messier 13, about 20% closer. It is visible to the naked eye under very good conditions. This image taken in September 2021.
