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

NGC 7112 = NGC 7113. Though Marth makes no mention of the star close west of the galaxy, there is little doubt that his object is the same as the one found by Swift 22 years later (Swift does mention the star). His position is just three arcmin north of the galaxy, and his description fits it well.

A puzzle here is Howe's note: "A search on two nights failed to reveal this (NGC 7112)." Swift's position is not that far off the galaxy (six seconds west and less than an arcmin north) and Howe has recovered many other of Swift's nebulae much further away from the nominal positions. Perhaps the star is close enough on the sky to the galaxy that its light swamped that of the much fainter galaxy.

Another puzzle is why CGCG ignored the NGC description of NGC 7112 with its note of the star and put the number on the fainter galaxy 4.2 arcmin to the south. My guess is that they had two NGC numbers at hand and two galaxies on the sky, and simply dumped the numbers on the galaxies without much thought.

Published comments

The RNGC (Sulentic and Tifft 1973) notes that this is a 15.5 mag galaxy. Their coded description reads EON,LBM,DKPCHS NRCT.
