DeLisle Stewart discovered IC 4784 = D.S. 526 on a plate taken on 20 Jul 1901 at Harvard's Arequipa Station. He noted "cF, S, R, bM." There is nothing at his position but 10' N is this galaxy, which fits the description. The error was first caught by Lauberts in the ESO. Corwin notes that Stewart probably missed the companion due to the superimposed star.

600/800mm - 25" (10/16/17 - OzSky): at 397x; moderately bright, fairly small, roundish, ~45" diameter, very small bright nucleus increases to the center. A mag 12.6 star is 0.9' SE and a mag 13.5 is 1.6' E. Forms a pair with LEDA 93561 2.2' SE. The companion was a difficult low surface brightness glow attached on the southwest side of a mag ~13.5 star, roughly 15" diameter. IC 4784 is located 37' ENE of IC 4765 in the Pavo II cluster = ACO S805.
