Eight of the NGC entries in Lynx have a confused history, discussed here to avoid unnecessary duplication. As noted at their entries, NGC 2463 was discovered by John Herschel, and NGC 2469 by William Herschel, then reobserved by John. Their positions were reasonably accurate, and there is no doubt of their identification. But in 1851 Bindon Stoney, working for the 3rd Lord Rosse, recorded a "great many knots, reckoned 10 nearly in a line pf", meaning running east and west. As shown in the image above there are six galaxies running in a nearly east-west line in the area in question, two of which are the Herschels' previous discoveries. Unfortunately, no positions were measured by Stoney, and in compiling his General Catalog Herschel included the supposed "novae", but with approximate positions presumably based on a general description of the region by Stoney (I seem to recall reading a discussion of a sketch of the region, but have not found the reference involved). Following Herschel's lead, Dreyer included the eight objects in his NGC, with the designations NGC 2458, 2461, 2462, 2464, 2465, 2471, 2472 and 2473.
 Guillaume Bigourdan observed the region in 1886, recording moderately accurate positions for eight of the ten objects (all but NGC 2472 and 2473); Dreyer notes this by crediting the 3rd Lord Rosse and Bigourdan in his entries for the eight objects. Only four of Bigourdan's observations were of galaxies, the other four being groups of one, two or three stars (at least as best estimated by recent review of his positions and the area in question). So two of the six galaxies shown in the illustration were not observed by him, nor does it seem likely that they were observed by anyone else. Since there are two galaxies in the east-west line that have no corresponding NGC entries, and two entries (NGC 2472 and 2473) that do not correspond to any known object, modern usage (or perhaps more accurately mis-usage) has assigned the two unlisted galaxies to the two unused entries, further complicating the situation.
 As a result, two of the ten NGC entries correspond to the Herschels' observations, two to Bigourdan's observations of actual nebulae, four to Bigourdan's observations of minor stellar groupings, and two to a modern assignment of the NGC numbers to the two galaxies not otherwise accounted for. With such a history it is hardly surprising that several of these NGC entries are assigned to different objects by different references.
