Globular Cluster in Libra

Uploaded 5/31/02

This 8.4 magnitude object is one of the few interesting objects in Libra, being a small constellation near the zone of avoidance for galaxies, it is nearly barren. 11 arcmins in size, the typical magnitude of 13 - 16. Visually, this object is a low surface brightness object like M55, and few stars can be resolved in the eyepiece. The typical orange and blue stars are apparent, a background haze of blue giant stars mixed in with orange super giants.
