Notes:

According to "Star Cluster", by Brent Archinal and Steven Hynes, the size of this open cluster is 4.0 arc minutes. In the Comments we find "DSFG: Probably not a cluster." This object (centered) looks to me as much like cluster as most of the other Czernik clusters I have imaged recently! The very faint nebulosity that runs diagonally across the center is part of the IC 1805 complex. See this image of the IC 1805 complex by Jay Ballauer, that shows the faint plume streaming to the NE from the 'Heart Nebula'
