  The classical Cepheids CE Cas A, CE Cas B, CF Cas, and CG Cas are likely
members of the binary open cluster comprising NGC 7790 and Berkeley 58. The
clusters are of comparable age and in close proximity, as deduced from
differentially dereddened $UuB_PBVGR_P$ photometry, and Cepheid period-age
relations. Gaia DR3 astrometric and spectroscopic solutions for the clusters
are likewise consistent. Conversely, the seemingly adjacent open cluster NGC
7788 is substantially younger and less distant.
