Wilhelm Tempel discovered NGC 4829 in 1882, along with NGC 4820 and 4823. In list V (AN 2439), he mentions "Quite close to the south [of N4825] are three more faint nebulae.", although no positions were measured. The NGC position matches PGC 44299 at 12 57 24.4 -13 44 15 (2000), so the position may have been communicated directly to Dreyer.

The PGC reverses the identifications of NGC 4829 and 4823. RNGC misidentifies NGC 4823 (2.3' north) as NGC 4829. This error was listed in my RNGC Corrections #5.

400/500mm - 17.5" (5/17/90): extremely faint and small, glimpsed for moments with averted. A mag 13.5 star is 1.8' S and a mag 12.5 3.6' SSW. Third of three and 5.3' SSE of NGC 4825. NGC 4823 is 2.4' N but was not seen.

600/800mm - 24" (5/25/14): very faint, extremely small, round, 12" diameter. Located 5.3' SE of NGC 4825 and second brightest of 3 faint companions, with NGC 4823 2.4' N and NGC 4820 6.0' WNW. Observed at 27° elevation (nearly 3 hrs past the meridian).
