M92 - Globular Cluster in Hercules

A beautiful globular cluster in Hercules, M92 is often overshadowed by its larger upstart M13. It is an example of an Oosterhoff type II globular cluster, which means it belongs to the group of metal poor clusters (primarily only hydrogen and helium). It is about 110 light years in diameter and approximately 26700 light years distant. This is a 2.3h unguided exposure through my 12″ Meade SCT using an ASI2600mc camera.
