History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 737 is a line of three stars in the corona of NGC 736. This object was variously seen as a single star and as a nebula by the early observers. Lord Rosse seems to be the first to list it as possibly nebulous, so Dreyer included it in the NGC. Reinmuth found only the three stars at the place of Lord Rosse's nebula (shown in his sketch of the group around N736, and measured micrometrically by him in October 1850), and that is all that I see there on the POSS, too.
Historical observations
Birr Castle/Lord Rosse
Lord Rosse recorded this object as a stellar nebulosity, perhaps a faint star, 27 seconds north of the galaxy NGC 736.
Burnham, S.W. (1894)
Publ.Lick.Obs. Volume 2. "Observations of Nebulae with the 36-inch Refractor of the Lick Observatory", p 168.
"The 36-inch shows that this is not a nebula, but a faint star, 13.5mag. .. there is no trace of nebulosity about either star. There is no doubt that No 737 should be rejected as a nebula from any future general catalogue."
Published comments
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads *** DC.
