Messier 13 (NGC 6205) is a globular cluster of several hundred thousand stars in the constellation Hercules. M13 is also known as Hercules Globular Cluster. Edmond Halley discovered it already in 1714. The globular cluster has an apparent magnitude of 5,8 mag and therefore is well suited for observation and astrophotography by amateur astronomers.
