Stephane Javelle discovered IC 1900 = J. 3-973, along with IC 1901 and 1902, on 18 Jan 1898. He reported "F, nearly R, 30", gbM, 14 mag stellar ncl."

600/800mm - 24" (2/5/13): brightest and first in the trio of IC galaxies. At 375x appeared fairly faint, small, elongated 4:3 E-W, 24"x18", increases to a small bright core and stellar nucleus.

24" (1/12/13): brightest in a trio (KTG 10) with IC 1901 2.9' SSE and IC 1902 3.7' NE. At 375x appeared faint to fairly faint, very small, elongated 3:2 E-W, ~20"x14", very small brighter nucleus. Located 2.9' ESE of a mag 11.3 star.
