Continuing the theme of clusters of clusters, here is a quintuple cluster (5 clusters in the same frame) that lies near the right end of the "W" of the constellation Cassiopeia. Above center is the well-known and bright cluster NGC 663. In the upper-left and upper-right corners are NGC 654 and NGC 659 while at the lower left is IC 166, which is comprised entirely of old, red stars. The small concentration of stars a little to the upper right of bottom center is open cluster Berkeley 6. The field of view here is about 1.5 degrees wide.
