Type: galaxy, Sbc

Size: 4.365′ x 1.445′
Synonyms: H I-015
Discovered in 1784 by William Herschel with an 18.7-inch f/13 speculum telescope. He called it "cB mE sp nf. sbM. 4 or 5' long."
A supernova erupted in this galaxy in 1965 (14.0p)
The RNGC (Sulentic and Tifft 1973) notes that this is a 11.5 mag galaxy. Their coded description reads EL,BM,MINC,PCHYDSKST.
Tom Lorenzin, in the e-version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "11.4M; 4' x 1' extent; bright, NNE-SSW-oriented, oblong spiral seen obliquely; Peculiar GAL N4668 (13M; 1.5' x 1' extent) 7' to ESE."
Steve Coe, observing with a 13" f/5.6, notes: "Pretty bright, pretty large, bright middle with a stellar nucleus at 165X. Much elongated 2.5 X 1 in PA 45. There is a nice, delicate triple star to the south."
Observing site: Little Bennett Regional Park
[12h 45m 6s, -0° 28' 0"] An almost edge on smudge.
Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
This very faint galaxy's spiral arms are just barely seen almost edge on as a grayish smudge of light.Around this galaxy I have found plenty of areas of uneven brightness.However this galaxy's shape is elongated and well defined.This galaxy measures 4'*1'with PA NW/SE.The nucleus of this galaxy grows only slightly brighter compared to the spiral arms of this galaxy.
