M22 is a beautiful globular cluster in binoculars and expodes into detail with a medium size scope.  Nearby M28 is a nice if not remarkable globular cluster.  Part of the fun here is that there are TWO SMALL GLOBULAR CLUSTERS hidden in the image :).  Look in the large image for NGC 6638 & NGC 6642!    RRGB = 30/30/30.
