Modern observations
Tom Lorenzin
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
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."

Sky Conditions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
Instrument:12-inch Dobsonian.
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.
