M-92
This is a fine, bright globular cluster, visible to the naked eye under very good conditions, and would be observed more often if it were not for its close proximity to M13. It is only slightly less bright but about 1/3 less extended than M13, 7-8' in diameter, easily resolved, and is sharply brighter towards the center. It appears to me to be slightly elongated in the NE-SW axis.
According to newer sources, M92 is about 26,000 light years distant, only little more than its brighter apparent neighbor M13.
