Herbert Howe discovered IC 2375 = Ho I-9, along with IC 2377 and 2379, on 22 Feb 1898 with the 20" refractor at the Chamberlin Observatory in Denver. He noted "F, vS, elongated at 90°, 1st of 3" and his micrometric position matches MCG -02-22-014 = PGC 23672.

400/500mm - 17.5" (2/8/97): first and brightest of a close trio with IC 2377 1.6' E and IC 2379 2.1' ENE. Faint, moderately large, elongated 3:1 E-W, 1.5'x0.5', even surface brightness. The group lies near two mag 11 stars oriented SW-NE.

600/800mm - 24" (2/16/15): first in a striking trio of IC galaxies. At 322x; appeared fairly faint to moderately bright, fairly small, very elongated 7:2 E-W, 0.8'x0.25'. IC 2377 lies 1.6' E and IC 2379 2.1' ENE.

In addition, I picked up MCG -02-22-011 14' SSW (same redshift as triplet; the quartet forming LDCE 574). MCG -02-22-011 was comparable to the ICs and appeared fairly faint, small, elongated 5:3 N-S, ~25"x15", small bright core. A mag 12.3 star is off the southeast side [30" from center].
