NGC 6293 -- Globular Cluster in Ophiuchus
The Best Globular of the Night
NGC 6293 was the most pleasing of the four Herschel 400, Globular Clusters, visited on the
night of July 18, 2020 at Carrs Mill Park.  Of the four, NGC 6293 was the only Globular Cluster
that showed any structure in the small 110mm refractor.  Although, the stars that make up this
cluster were all below the resolution of my telescope, the cluster still took on three-levels of
brightness.  The core was bright and distinct and surrounded by subtle bright extensions that
seemed to bleed into the cluster’s halo.  The halo itself did not appear as a uniform glow but
looked somewhat dappled.  All in all, it was the surprise of the evening.
