John Herschel discovered NGC 461 = h2400 on 25 Sep 1834 and recorded "pB, R, glbM, 20 arcseconds". There is nothing at his position but 30' S is ESO 352-033 = PGC 4636. He noted in his observation that because he was not able to relocate this galaxy he probably made an error in the declination. So, h2400 = ESO 352-033 = PGC 4636. The RNGC position is 1.1 tmin too far W and 7' S (17' SW) of this galaxy and it is plotted incorrectly on the first edition of Uranometria 2000. MCG (-06-04-002) missed assigning the NGC number.

400/500mm - 17.5" (10/4/97): very faint, small, round, 30" diameter, low surface brightness, no concentration. Lies in a barren field with a mag 13 star 3.3' SW. Incorrect position in RNGC and on U2000 atlas.
