George Johnstone Stoney, Lord Rosse's assistant, discovered NGC 2830 on 13 Mar 1850. It was one of "15 knots in all". A sketch made in March 1851 shows NGC 2831 labeled Gamma and measured at 1.2' southwest (PA = 237°) of NGC 2832. John Herschel incorrectly equated this galaxy with H I-113 = h582 in the GC, and Dreyer repeated the error in the NGC. But the Herschel numbers apply to brighter NGC 2832. The NGC RA is 6 seconds too large.

MCG reverses the identifications of NGC 2830 and NGC 2831. According to the "New Description", RNGC has also reversed these identifications. This error was included in my RNGC Corrections #1 and was discussed in detail by Malcolm Thomson in the Webb Society Quarterly Journal for Jan 1978.

400/500mm - 17.5" (1/31/87): very faint, low surface brightness, edge-on WNW-ESE. First of three in a triple system with NGC 2831 0.9' ENE and NGC 2832 1.4' NE of center in the core of AGC 779. Also nearby is NGC 2825 3.9' W.
