IC 4868 = WDS J19336-4554AB is a close (3.9 arcsec in 1999) double star. Innes identifies it clearly as CD-46 9730, and describes it as "... an even patch of light 3 arcsec by 2 arcsec." The only things distinguishing it from a single star on the southern survey plates are a very slightly elongated image and a second faint set of diffraction spikes. There are two fainter stars about 10 arcsec away, the brighter to the northwest, the fainter to the west-northwest; scattered light from these might have added somewhat to Innes's impression of nebulosity.

I've adopted UCAC positions for the conglomeration; note that the Tycho-2 position for the brightest star is very slightly different, though still within the combined measurement errors.
