History and Accurate Positions for the NGC/IC Objects (Corwin 2004)
NGC 4727 = NGC 4740. This is the brightest of a group of galaxies, and the brighter of a close pair (NGC 4724 is the fainter of the pair). It was seen by both Herschels, as well as by Tempel, Swift, Bigourdan, and Howe. Considerable confusion in the NGC and IC numbers has resulted. See NGC 4740 for the story, and also see NGC 4726 for one of Tempel's nebulae that almost got away.
Historical observations
William Herschel (c.1784)
Synonyms: H II-298
Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, pL, lbM, 0.5' preceding is a small suspected stellar."

Coe, using a 13" f/5.6, notes: "Pretty bright, pretty large, round, brighter in the middle at 220X."
