Discovered in 1783 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "F cL mE bM easily resolvable."
This 12th magnitude spiral galaxy is recorded in the NGC as "pretty bright, pretty large, much elongated PA 64 , between three stars, easily resolvable."
Burnham calls it "pretty bright, pretty large, much elongated, brighter in the middle to a nucleus, with Saturn-like inner ring."
A supernova erupted in this galaxy in 1984 (14.0pg)
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.0 mag galaxy. Their coded description reads S,EL,BM,DIF,BRGNRNUC.
F, 5'x1', E 55deg; spiral with rather compact but well defined whorls and B sharp stell.. surr. by a rather brighter patch of nebulosity. There are signs of absorption in n.p. portion. Many other small nebulae in this field.
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "12M; 5' x 1' extent; fat, NE-SW-oriented slash with bright center and stellar nucleus."
Steve Coe, using a 17.5" f/4.5, notes: "Faint, pretty small, much elongated 4x1 with a bright nucleus. There is a hint of a dark lane with averted vision at 135X. There are two attendant galaxies 20' to the NE, they are both very faint, small and round."

Location: Campsite (23 16 South - 29 26 East).
Telescope: Meade 8" 18mm eyepiece, 36 arcmin f.o.v.

Sky conditions: Not very good.
Description: Very faint spindle 5x2, north to south with a suggestion of brightness to the nucleus. To the west just outside this galaxy two separate stars visible and two arc minutes away another pair of stars, resembles Jupiter and its moons. A faint little star on the south tip embedded. Just visible outside the field of view NGC 7180 and NGC 7185.

Very faint spindle 5x2, NE-SW with a suggestion of brightness to the nucleus. To the north just outside this galaxy two separate stars visible and two arc minutes away another pair of stars, resembles an elongated Jupiter and its big moons. A 12 Magnitude star is embedded on the southern tip of the galaxy. Just visible outside the field of view to the west is NGC 7180, NGC 7185 and to the north NGC 7188. Very elongated NE-SW and the brightest in the group. The nucleus is outstanding and bright. The galaxies to the north show just wimps of light, very small and slightly round in shape.
