| E-P5 + Rokinon 135mm f/2, ISO1600, 60 s. 2-deg square. |
The cluster is located just past the west end of the "W" asterism of Cassiopeia. It would be even more visually impressive if it wasn't embedded in the star field of the northern Milky Way. The cluster is estimated to be about 8000 ly distant. There is no distinct boundary, but the densest section in the above image corresponds to a diameter of about 35 ly at that distance.
