Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F, cL, R, vgbM, south following a star."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads SB,BBAR,DIFPDARM N SOUTH ARM VCOMPLEX & KN.
This galaxy appears on page 49 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).

Steve Coe, using a 13.1" f/5.6, notes: "NGC 7741 Pretty faint, very elongated, round, somewhat brighter in the middle, there is a double star on the NW side at 135X. This is the type of object that shows itself best on a clear, sharp evening. On a fuzzy night it is just a dim grainy object. On a night I rated 8/10 the central bar structure was immediately seen and averted vision showed some faint outer arm structure at 165X."
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12.1M; 3.1' x 2.5' extent; faint and fuzzy; appears irregular in shape; two stars (12 and 13M) immediately to NNW; 9M star 4' NW; !good supernova prospect! see photo at HAG-49."
