About this Object:  

Forever to be regarded as the "other" globular in the constellation Hercules, M92 doesn't get the credit it deserves.  Slightly smaller, and slightly more faint than it's bigger neighbor, M13, M92 is every bit as spectacular.  Just one look of the photographs should give enough indication as to the quality of both objects. (to compare, see M13 <here>).  

Visually, this object is quite apparent in scopes of all sizes in dark skies.  While it's not quite as easy to resolve the stars at the center of the cluster as with M13, a larger scope will actually reveal more stars since the core itself appears a little more graduated, with more levels of brightness throughout the cluster itself.
