Comments:  These were two pretty different nights.  In June the first quarter moon was present.  It was cool with a low in the 50s with a slight breeze.  The second night was warm and quite humid with a low about 65 and calm.  I even had a layer of ground fog for about 30 minutes a little after midnight.  M80 is a fine globular with its size roughly 95 light years across.    This dense stellar swarm contains several 100,000s of stars.  It is one of the densest globulars in the Milky Way Galaxy.
