Get to know Hercules Globular Cluster
An ancient, densely populated star cluster, catalogued as M13. A dark sky and suitable equipment can reveal structure that is difficult to see under city lighting. Space-telescope images combine long exposures and processing; the eyepiece view is different. Precise coordinates have not been added to this curated entry, so it is excluded from computed sky positions.
