Discovered in December 1783 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB cL vgbM having a nucleus. Round."
Burnham calls it a 11.5 mag spiral galaxy in Cancer, measuring 2.2' x 1.5', which is considerably bright, considerably large, slightly elongated, very gradually then very suddenly much brighter to the middle.
The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads BE,R,BM.
This galaxy appears on page 10 of "The Hubble Atlas of Galaxies" by Allan Sandage (1961, Washington, DC).

Hartung notes that "30cm discloses a conspicuous round haze about 1.5' across, rising much to a bright nucleus but with no sign of structure. 10.5cm shows the nebula clearly though faintly."
Houston notes that this 11th mag galaxy is easily seen in a 4-inch refractor as a round glow about 2' diameter. In larger telescopes it is a very pleasing sight, A row of six 9th mag stars lies about 10' east of the galaxy."
Steve Coe, using a 13" f/5.6, notes: "Bright, large, elongated 1.8 X 1 in PA 165 and much brighter in the middle at 220X. The arms of this galaxy are nicely mottled and the central core is elongated 2 X 1 in the same PA as the main body of the galaxy."
Steve Coe, SACNEWS On-Line for March 1996, notes: "bright, large, elongated 1.8 X 1 in PA 165 and much brighter in the middle at 220X. The arms of this galaxy are nicely mottled and the central core is elongated 2 X 1 in the same PA as the main body of the galaxy."
Listed by the Herschel Club, described as "appearing circular, with bright nucleus, use averted for best view. 8-inch, 48x."
Sanford comments that the galaxies in Cancer are mainly faint, "but NGC 2775 is a high-surface-brightness object. With a telescope of 8-inch aperture, it appears as a round, 10th magnitude glow, brighter in the middle."
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.5M; 2.5' diameter; round, soft glow with fairly bright nucleus; !good supernova prospect! see photo at HAG-10."

NGC 2775 Donald J. Ware:"The first of many galaxies to come. This object is about 4'x2', oriented NNW-SSE, has a very bright core, with fainter extensions to the listed dimensions. The center appeared to me to be somewhat granular."
