DeLisle Stewart discovered IC 4705 = D.S. 463 on a plate taken on 20 Aug 1900 at Harvard's Arequipa Station. He noted "eF, eS, R."
600/800mm - 24" (4/12/08 - Magellan Observatory, Australia): moderately bright, fairly large, fairly diffuse glow with only a weak concentration, elongated 4:3 SW-NE, 1.2'x0.8'. A 20" pair of mag 14 stars is at the south edge of the halo and two extremely faint stars are superimposed on the north side. Located 5.1' SSE of IC 4704, nearly at the midpoint of a line connecting IC 4704 and a mag 8 star (HD 168873), located 6' SSE of IC 4705. IC 4712 lies 14' E.
24" (4/11/08 - Magellan Observatory, Australia): at 260x appeared fairly faint, moderately large, slightly elongated 1.0'x0.8', fairly low surface brightness with a weak central concentration. Located 6' NNW of mag 8 HD 168873 and 5' SSE of IC 4704.
