Description

Messier 92 is a fine globular cluster that is often overlooked due to its close proximity to "the great globular cluster" Messier 13.   It's a tight cluster containing 330K stars.   It is supposedly visible naked-eye under very good conditions (although I've never seen it this way).   It has low metallicity,  and has an age estimated at ~11 billion years.

Description: Doubled integration time, eliminated bad exposures (now FWHM is ~0.3 better), and kept a slightly wider crop to keep some of the interesting galaxies in the field.
