Not imaged that often! Mainly maybe cause eye catcher M13 is not to far away. But long exposures reveal a fair amount of stars in M92, making it a beautiful globular cluster! The dense, bright inner core is not processed to get these stars visible individually. Could have done that, I took the underexposed subs for it, but it takes that snappy look away. I therefor didn’t bother correcting that. I hope you forgive me!
