Stephane Javelle discovered IC 1087 = J. 336, along with IC 1088, on 28 May 1891. His reference for IC 1087 and IC 1088 was a mag 9-10 star at 15 07 02.6 +03 50 50 (2000). His offsets for #336 = IC 1087 are -19.8 seconds of time and -4' 14.8" dec. This places IC 1087 at 15 06 42.8 +03 46 35 (J2000), a perfect match with the northwest galaxy of the pair. IC 1088, though, refers to a mag 15 star 1.3' NE of IC 1088. It is often misidentified as the southeast member of the pair.

400/500mm - 17.5" (6/29/00): this is the brighter of close pair of difficult galaxies. At 220x, it appeared as an extremely faint and small glow, perhaps 25" diameter. At 280x a confused glow was visible and with extended viewing a close companion (UGC 9710) was just resolved to the southeast . With concentration both members could almost be held continuously. A mag 15 star lies 1.3' NE (this is IC 1088).

600/800mm - 24" (6/30/16): at 322x; fairly faint, fairly small, slightly elongated WSW-ENE, ~24"x18", small bright nucleus. IC 1087 is the brighter of a close pair with UGC 9710 (misidentified as modern sources as IC 1088) just 32" SW. IC 1088 is a mag 15.5-16 star 1.2' NE.

Mrk 1392 (brightest in the trio WBL 542) lies 12' SW. It appeared fairly faint, fairly small, elongated 3:2 SW-NE, 30"x20", strongly concentrated, small bright nucleus (Seyfert 1 nucleus). CGCG 048-116, 2.0' E, is fairly faint, fairly small, slightly elongated, 0.5'x0.4', fairly even surface brightness. CGCG 048-117, 3.8' SE, is faint, small, round, stellar nucleus surrounded by an 0.3' halo.
