Lewis Swift discovered IC 1762 = Sw. XI-31 on 6 Sep 1897 and called it "eeeF; pS; R; 7m * in field [north-following], another susp[ected]." His position is 5' too far southeast (very common in his last year of observing) but a mag 6.4 star is 13' NE, confirming the identification. Delisle Stewart found the galaxy again on an Arequipa plate in 1899 and described the galaxy as "cF, S, vE at 45°, cbM."

600/800mm - 24" (12/6/18): at 260x; very faint, moderately large, very elongated 3:1 or 7:2 SW-NE, 0.9'x0.35'. Appears as a ghostly streak (thicker in the middle) with averted vision and appears fainter than the listed magnitude. Located 13' SW of mag 6.4 HD 12135. IC 1759 lies 15' due north.
