DeLisle Stewart discovered IC 4728 = D.S. 480 on a plate taken on 20 Jul 1901 at Harvard's Arequipa Station. He noted "eF, S, cE 170°, * N, bM."

600/800mm - 25" (10/15/17 - OzSky): at 397x; fairly faint to moderately bright, moderately large, very elongated 3:1 ~N-S, 1.5'x0.5', bright core. This outlying member of ACO S805 = Pavo II Cluster is in rich star field with a mag 13.8 star 1.2' SSE and a mag 13.6 star 1.6' NNW. A fairly wide pair of mag 10.9/11.6 stars (~22" separation), with a third 11.9 star nearby, lies 3.5' NNE. IC 4727 is 10' S.
