NGC 6304 & NGC 6355 -- Globular Clusters in Ophiuchus
Two Small Herschel-400 Globular Clusters in the Serpent Bearer
Neither of these globular clusters are doable from my suburban backyard.  But good clear skies
over nearby Alpha Ridge Park made these tiny globular Clusters possible in my 110mm
refractor.  Neither could be resolved.  NGC 6304 does have a flattened east-west core, while
the slightly brighter and larger NGC 6355 appeared spherical.
