Hercules Cluster M13
Steve Moore 2000
OBJECT M13 Globular Cluster in Hercules RA 16.42 DEC +36.28. This popular globular is easy to find, and at magnitude 5.5
it can been seen by naked-eye in very dark skies. Viewing through binoculars will not resolve the core, but a small refractor should pick
up the edges of this object. Larger scopes will help see some of the clusters 750.000 stars. Globular's are not easy to photograph as any
slight tracking error, or focus error will show.
