NotesThere is some confusion over the application of the name Ruchba. Most sources attribute it to Omega2 Cygni as here, but others prefer to assign it to the nearby (and slightly brighter) Omega1 Cygni. A very similar name, Ruchbah, is also used of an entirely unrelated star, Delta Cassiopeia, which forms part of Cassiopeia's Chair.
