Vision In Time Observatory - Peoria, AZ

Some astronomers call this cluster the "Great Globular Star Cluster of Hercules." Halley wrote about it as early as 1714. Messier put it in his catalog as M13. This image was taken with a LX200 classic and a 416 Meade CCD in black and white. The star cluster is about 21,000 light years away.
