History and Accurate Positions for the NGC/IC Objects (Corwin 2004)

NGC 5804 is UGC 09627. In spite of a good position in the NGC, RNGC has managed to mangle the identifications of not just this, but also NGC 5794, NGC 5797, and NGC 5805 (which see), also in the area. N5804 has a bright Seyfert nucleus, easily visible on the Sky Survey prints as well as visually.
