Discovered in 1786 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "vB, R, vgbM, 1.5' diameter."
Observations with the 72-inch f/8.8 speculum telescope at Birr Castle noted "suspect spirality; light unequal."
Burnham calls this a 11.6 spiral galaxy in Cassiopeia, measuring 1.2' across which is "considerably bright, pretty large, round, very compact spiral."
The RNGC (Sulentic and Tifft 1973) notes that this is a 12.5 mag galaxy. Their coded description reads BE,R,BM,HISB.
John Bortle (Webb Society Quarterly Journal, January 1976) using 10x50 binoculars, estimates the visual magnitude as 11.3.
Listed by the Herschel Club, described as "a round, bright nucleus, nebulosity made out well through the eyepiece. Situated near a couple of bright field stars. 8-inch, 70x."
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes "11.6M; 1.2' diameter; small, round and bright; very compact spiral; see Burnhams Celestial Handbook-I-534 for photo; good supernova prospect."

Immediately stood out as a small, bright object, suddenly bright towards the center. Seemed very similar to an unresolved globular cluster. It's brightest part of the core was perhaps slightly off center.

This is a subsequent observation to one made very recently.. Small, fairly bright and round..similar to NGC 7217 that was observed on the same night in size, and globular-like appearance. However, even though there is sudden brightening near the center, it is clearly NOT as stellar looking as NGC 7217.

Description: This little galaxy is very bright and withstands magnification very well. The best view came at 821x. The galaxy was brighter in the middle and the core was non-stellar. A small condensation was seen near the bottom edge. A prominent dust lane was apparent on the left side. Some possible mottling was seen on the right side, but nothing definite.
