Stock 6 is a small open cluster (at the center of the image) located in Cassiopeia. This is one of 24 open clusters compiled by Jurgen Stock in the 1950s. A full list can be found here - http://www.deepskype...wiki/List:Stock (when and if the reference comes back online).


NGC 886 is a much brighter open cluster just below center.


Berkeley 63 is a small, tight open cluster located to the right (west) below the center.
