Albert Marth discovered NGC 1875 = m 98 on 18 Nov 1863 with William Lassell's 48" on Malta and logged as "eF, S, R." His position matches MCG +01-14-032 = PGC 17171, the brightest member of HCG 34. VV 169 = Arp 327 is a triplet of distorted galaxies just southeast.

400/500mm - 17.5" (2/8/97): faint, very small, round, 20" diameter, very faint stellar nucleus. Located 1.0' E of a mag 13.5 star. No other members of HCG 34 seen.

17.5" (12/23/89): very faint, very small, round, faint stellar nucleus. A mag 14 star is 1' W. This galaxy is the brightest member of HCG 34 including an extremely faint interacting triplet just SE which was not seen.

600/800mm - 24" (2/9/13): NGC 1875 is the dominant E or S0 galaxy in HCG 34. At 375x it appeared moderately bright, fairly small, round, 0.4' diameter, well concentrated with a small brighter core. A mag 13 star lies 1' W and a mag 16 star is just 0.4' W of center. Two additional members were barely seen to the southeast; HCG 34C 0.9' SE and 34B 1.2' SE.

900/1200mm - 48" (10/24/11): bright, round, 30" diameter, brighter core. A mag 13 star lies 1' W. The other three fainter members (interacting chain Arp 327) are in a string to the southeast with HCG 34D 0.5' SE, HCG 34C 0.9' SE and HCG 34B 1.2' SE. HCG 34D is extremely faint and small, round, 6" diameter, HCG 34C is faint, very small, slightly elongated E-W, 12"x8" and HCG 34B appears faint, very small, elongated 2:1 ~N-S, 20"x10". I also picked up 2MASX J05215739+0643182, a fairly faint (mag 16.7B) galaxy 3.5' NE.
