Brocchi's Cluster
Brocchi's Cluster is actually an asterism, not a true cluster, as many of
the members do not have the same proper motion. Nevertheless it is a bright
and beautiful showpiece in the constellation Vulpecula that is visible to
the naked eye, and best viewed in binoculars. The tiny but very dense open
cluster NGC 6802 near the left edge is a striking contrast, and is a true
cluster of stars. This asterism is also known popularly as the
Coathanger.
You may notice in the top-right quadrant a little red smudge. It turns out
this is Sh2-83A, a small nebula.
