E.E. Barnard discovered IC 4565 on 20 Aug 1890 in a sextet (5 in IC) with the 12-inch refractor at Lick Observatory. He noted "faint, round, gbM." and placed it accurately in his notebook sketch (published in 1906).

400/500mm - 17.5" (6/27/98): this galaxy is the faintest of six in the IC 4562 group. Required averted vision to view this extremely faint "knot", only 5"-10" in diameter. Nearly equally spaced with a mag 15 star 1.8' NNE and a mag 12 star 3.7' NNE. Located 6' SSE of IC 4564.
