NGC 5053 is a faint and somewhat sparse globular cluster in Coma Berenices. It has a
fairly large apparent size of 10 arc minutes and has a listed magnitude of 9. That said, it
is known to be a visual observing challenge in scopes of 12 inch aperture and smaller
and requires dark skies to resolve stars. The image shows mag 16.6 elliptical galaxy
PGC 46161 to the upper right of the cluster.
