Historical observations
William Herschel (c.1784)
Synonyms: H I-288
Discovered in 1802 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vB, cL, lE, suddenly mbM."
Webb, T.W. (1893)
In the 5th edition of Webb's Celestial Objects for Common Telescopes it is described as "nucleus like 11th mag star."

Doig, P. (1925)
Journal BAA, 35, p159
Slightly oval, vB centre. Luick photos show F spiral whorls, prob. 4' extreme diam.
Sulentic & Tifft (1973)
The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads R,HISBCT,DIFEXT HALO.
Arp (1966)
Listed as No. 225 in Arp's "Atlas of Peculiar Galaxies" (Astrophysical Journal Supplement, vol. 14, 1966.) He remarks "very faint diffuse outer arms, absorption one side of nucleus."
Modern observations
Walter Scott Houston
Houston calls this a "moderately bright galaxy . . it is an obvious 5'x3' oval glow in a 6-inch glass with an estimated visual magnitude of 10.5. A 4-inch will show it on good nights at low power, and once found it will stand closer scrutiny at 100x and 150x.
Ancient City Astron.Club (1980)
Listed by the Herschel Club, described as "very faint, small with bright nucleus. Low surface brightness noted, seen face-on. 8-inch, 48x."
Sanford (1989) Observing the Constellations
Sanford calls it a "relatively nearby spiral galaxy shining at magnitude 10 with high surface brightness some 4' in diameter."
Tom Lorenzin
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.6M; 4' diameter; soft, round patch with very bright core; two 7M stars nearby, one 8' to SE, one 15' to WSW; 25' to ESE is SP GAL N2715."
