Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pF, S, R, gbM, 15 arcseconds."
description reads: "pretty faint, small, round, gradually brighter towards the centre."

The RNGC (Sulentic and Tifft 1973) notes that this is a nonexistent object. Their coded description reads NF S.
This faint planetary nebula lies 2 south of 6th magnitude Nu Pavonis. It lies less than one degree away from the very similar planetary IC 4723. You will need a 12-inch or larger telescope on a very dark night to spot this dim 15th magnitude object. It is slightly flattened, measuring 19" by 15", and looks like a faint, out of focus star at high magnification. Because of its very low surface brightness, it shows no colour and appears a pale grey.
Vol 24 No 3 June 1971: "difficult, requires large aperture."
16-inch f/10 SCT (127x, 290x)
Very small and faint just seen with averted vision. Slightly oval E-W with a lovely short string of stars 7' to the NW. IC 4723 is 22' towards the east but not sure about the sighting.
