DeLisle Stewart discovered IC 4823 = DS 559 on a plate taken at Harvard's Arequipa station on 13 Aug 1901. He reported "vF, vS."

600/800mm - 30" (11/6/10 - Coonabarabran, 264x): fairly faint, moderately large,, elongated 3:2 SW-NE, 45"x30", relatively low even surface brightness. Forms a double with ESO 104-45A barely off the SE end [27" between centers]. The small companion is very faint, extremely small, round, 10" diameter. On first glance this double system could be mistaken for a single elongated oval as they seem to have a common envelope 1.1'x0.6'. Located 18' SE of NGC 6744 and 8.5' SW of mag 8.0 HD 178534.
