In the Appendix to the 1912 'Scientific Papers of Sir William Herschel' this object is described as "1784, March 11. A fine, bright nebula, much brighter in the middle than at the extremes, of a pretty considerable extent, perhaps 3' or 4' or more. The middle seems to be of the magnitude of 3 or 4 stars joined together, but not exactly round; from the brightest part of it there is a sudden transition to the nebulous part, so that I should call it cometic."

(Sulentic and Tifft 1973) notes that this is a 11.0 mag galaxy. Their coded description reads BSB,ALMRG,DKLNS, MUCH PERIPH PDDIF SSTR.

This is the major condensation in the Leo I cloud; it is centred on a dense core (3°x1.5°) including NGC 3351 (M95), NGC 3368 (M96), 3377 3377A 3379 3384 and NGC 3412.
writes: "They [M95 and M96] are not breathtaking to say the least, and for small telescope users a good description is that they are bright enough to see. M95 is a barred spiral. Most amateur telescopes will show a 10.5 mag central core. Close scrutiny will reveal it to be a gently squared-off circle."
Notes: "10.5cm shows a rather faint small hazy spot. With 30cm it is a bright symmetrical round haze nearly 3' across in a field of a few scattered stars; the outer parts are very faint and there is a small bright nucleus."
Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "9.7M; 4' diameter; medium bright with stellar nucleus; barred spiral with faint bar visible with larger aperture; see photo at HAG-48; 40' W of brighter M-96; !good supernova prospect!."
:" Round, about 3' in diameter with a bright core surrounded by a faint halo. This is a barred spiral."

Conditions: The most clear sky possible. Dark moon and stars magnitude 6 and fainter are visible with the naked eye. Excellent clean sky, limited star flickering and brilliant objects. Limiting Magnitude: 6.2.
Barred Spiral Galaxy located in Leo. Bright, well defined. Fairly low surface brightness. This galaxy has an oval shape with the outer regions just resolvable with a slight dust lane. The galactic nucleus has a very bright central bulge. No stars near the galaxy.
Observing site: Pinnacles overlook
[10h 44m 0s, 11° 42m 0s] Bright nucleus, faint disk, no sign of the bar.
