M92 in Hercules

M92 is a Shapley-Sawyer Class IV globular cluster lying 26,700 light-years from Earth in the constellation Hercules. And I say too bad that it is in Hercules because everyone views globular cluster M13 in Hercules but few shift their telescope a short distance from M13 to this other gem of a globular star cluster. a characteristic of Shapley-Sawyer Class IV globular clusters is that they still have a small dense, unresolvable core. However, the CDK17 resolved the stars in M92 right down to the center of the core. Colorful red giants and blue stragler stars are visible within the cluster. The spiral galaxy to the right of top center is PGC59984. The spiral galaxy along the top right edge is PGC 59938.

Exposures: L:R:G:B = 50:25:25:25 minutes = 2 hours, 5 minutes total exposure, completely unguided.
