DeLisle Stewart discovered IC 4596 = D.S. 428 on a plate taken in July 1899 at Harvard's Arequipa Station. He noted "F, S, vE at 40°, mbM, * N, prob. spiral."

400/500mm - 17.5" (7/22/00): extremely faint, very small, elongated at least 2:1 SW-NE, ~20"x10", low even surface brightness. A mag 14 star is close north [37" from center] and a triangle of mag 12/13 stars lies 3' NNE. Located 25' NW of globular cluster M80!
