Stephane Javelle discovered IC 1510 = J. 1-500, along with IC 1507, on 5 Nov 1891. He called it "faint, almost round, appears to have two centers of condensation. His description applies to this contact pair of galaxies though only a single IC designation was assigned. The mean position (from NED) is given.

600/800mm - 24" (9/7/18): at 375x; very faint, very small, round, 20" diameter, very low even surface brightness. IC 1510 is a double system, but I only noticed a single glow. Located 13' SW of mag 7.0 HD 223617 and 27' ESE of mag 6.5 HD 223346. A striking 30' linear string of stars begins 10' S of IC 1510 and extends NW to HD 223346.
