M 15 (NGC 7078) -- Globular Cluster in Pegasus
Great Pegasus Cluster
The Great Pegasus Cluster is my favorite Globular Cluster that can be observed from
Maryland.  There are brighter and larger Globular Clusters in the night sky over Maryland
but none match the visual magnificence of M15. The condense core and apparent
streamers of this 100,000+ suns (along with a black hole at its center) packed within a
sphere a 160 light years across is truly amazing in the eyepiece.
