Description:
A sparsely populated open cluster that is limited by Phi Cas from the east. Prevailed by nearly a dozen stars of mag 10-11 with nearly identical colour and luminosity. In the background of these are fainter, nearly 13 mag stars of at least double the amount, which clearly form a cluster with their brighter companions despite the big difference in brightness.
