The Sailboat Cluster (NGC 225) is an open star cluster in Cassiopeia; its common name was given to it by Astronomy contributor Rodney Pommier for the visual pattern of its stars. (If you can’t see the sailboat, try tilting your head slightly to the right.) The blue reflection nebula associated with it is van den Bergh 4 and the dark nebula to the lower right is LDN 1291.
