Historical observations

Dunlop, James (1827)

James Dunlop discovered this object from Paramatta, New South Wales, and included it as No. 263 in his catalogue of 1827. Using a 9-inch f/12 telescope, he described it as "a small faint round nebula, 20 arcseconds diameter, a little brighter in the middle, following a group of pretty bright stars."

John Herschel (1847) Cape Observations

Discovered by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "pB, pL, R, gbM, 1'." On a second occassion he called it "F, L, R of lE, vgpmbM, 1', resolvable, with long attention it appears mottled. Perhaps Dunlop 263, with 3 minute correction in RA."
