Managed to get a quick image of M92 during special viewing session with Boothe Memorial Astronomical Society (BMAS) on Sunday evening.  Messier 92 is a very bright (+6.4) globular cluster located in the Hercules constellation.  This image is only 7.5 minutes total exposure, I've taken other images of clusters with much longer exposures and they aren't as bright.  It has a diameter of 115 light-years and estimated to have 400,000 stars.  One more Messier object off my list (Messier Objects with an ED80 by Kurt Zeppetello), although I plan to get a longer exposure of this object.
