E.E. Barnard discovered IC 2193 on 12 May 1888 with the 12-inch at Lick Observatory. This was three nights after he found IC 2194, 2196 and 2199 - his first discoveries at Lick. He noted (from his logbook), "Found a new nebula in field with those of May 9th, and north of them. Small, hazy, faint, less than 1' s.p. 10m star." Although the star is closer to 13th magnitude and his position is poor, the identification is certain.

Harold Corwin notes that Javelle's IC 2192 is not identical to IC 2193 as suggested by Dreyer in the IC description. IC 2192 is an extremely faint galaxy at 07 33 20.3 +31 21 41 (J2000).

400/500mm - 17.5" (1/23/93): faint, small, elongated 5:2 WSW-ENE, small bright core. A mag 13.5 star is at the north edge 32" NNE of center. IC 2194 lies 10' SSE and IC 2196 lies 11.4' SW.
