The RNGC (Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads ALMEON,B,DIFPERIPH SSTR SUSP.
Houston notes that this 9.3 mag galaxies "distinctive cigar shape can even be picked up while sweeping." He was able to locate it with a 3-inch telescope at 60x. "The galaxy is also a pleasant sight in a 10-inch at 120x." He also called it "a neat little spindle of light that I estimate as magnitude 9.6. It is a nearly edge-on galaxy that appears a little over 1' long."
Listed by the Herschel Club, described as "edge-on, a large needle of light. Very pretty. 8-inch, 70x."
Tom Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10.6M; 9' x 1.3' extent; spindle shaped, edge-on spiral; axis oriented NE-SW; bright center; good supernova prospect to the NW of the Sigma CNC clan."
Observing site: Pinnacles overlook
[8h 52m 42s, 33° 25m 0s] A wonderful edge on Sc, large, a bit mottled with no obvious dust lane. Burnham lists this as an Sb.
Sky Condtions:The fainter parts of the Milky Way are barely visible.Haziness only visible on the horizon.Atmosphere stable with little interference.
This spiral galaxy's bright dust arms are seen edge on as this galaxy's elongated nucleus is oval and well defined.Around the outskirts of this galaxy I have found areas of uneven brightness.The nucleus of this galaxy is brighter compared to the spiral arms of this galaxy.This galaxy measures 4'* 0.8'with PA NE/SE.
