Historical observations

William Herschel (c.1784)

Synonyms: H I-104

Discovered in 1785 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB, cL, E nearly in the meridian, gmbM, F, rays."

John Herschel (1847) Cape Observations

Observed by Sir John Herschel at the Cape of Good Hope with an 18-inch f/13 speculum telescope. He recorded it as "F, pL, pmE, 2' long, 1.5' broad."

NGC/IC Dreyer (1888, 1895, 1908)

This 11.9 magnitude spiral galaxy is recorded in the NGC as "pretty faint, considerably large, pretty much elongated in PA 0 ."

Published comments

pB, 5'x1.5', E 145deg; B alm.stell.N.; a fine compact spiral with dark lanes between the whorls.

Sulentic & Tifft (1973)

(Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads S,LG,B,MINC,DKLNS SEV * SUP.

Modern observations

Hartung, E.J. (1968) Astron.Obj.South.Tel

Hartung notes that "with 30cm it is an elongated elliptical haze about 3' x 1' in pa 150 degrees, the central regions much brighter . . the extensions are faint and there is a small nucleus. 15cm is needed to show the elongation and the general form is clear at 20cm."

Ancient City Astron.Club (1980)

Listed by the Herschel Club, described as "elongated, very elusive, fairly large and faint, used averted vision. 8-inch, 43x."

Tom Lorenzin

Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.9M; 6' x 1.5' extent; soft, NW-SE-oriented slash with little or no center condensation; 70' due N of DBL ST Psi 3 AQR; very faint EL GAL N7600 (13M; 2' x 1' extent) is 55' due N of N7606."

Steve Coe

Steve Coe, using a 17.5" f/4.5, notes: "Pretty bright, pretty much elongated and brighter in the middle with a stellar nucleus at 165X."
