Heinrich d'Arrest discovered NGC 2929, along with NGC 2930 and 2931, on 21 Feb 1863. His position, measured on 3 nights, matches UGC 5126 = PGC 27398.

400/500mm - 17.5" (4/15/93): first and largest of a close trio in a line. Faint, fairly small, very elongated 3:1 NW-SE, 1.0'x0.3'. A mag 13 star is 1.7' NW. Located 10' NE of mag 7.1 SAO 80931 at the edge of the field. NGC 2930 lies 2.8' NNE and similar brightness to NGC 2931 5' NNE.

600/800mm - 24" (2/15/18): at 375x; first in a nice string of an equally spaced and collinear triplet. fairly faint to moderately bright, fairly small, elongated 3:1 NW-SE, 0.9'x0.3', slightly brighter bulging core. Located 11' NE of mag 7.1 HD 83145 and 20' ESE of mag 7.5 HD 83004. Brightest in a group (WBL 227) which includes NGC 2927, 2930, 2931, PGC 27435 and PGC 27434. PGC 27435, located 5.6' E of NGC 2929, was extremely faint (V = 15.6), fairly small, elongated 2:1 ~E-W, ~25"x12". It was often visible at 225x (10mm ZAO) and 375x (6mm ZAO), but I couldn't hold steadily for a significant length of time. PGC 27434, located 7' ESE of NGC 2929, was marginally glimpsed 1.2' ESE of PGC 27435. I probably only noticed the slightly brighter central region (~10") but too ephemeral (V = 16.1) to notice a shape. It only popped a few definite times but was verified in the same position.
