Historical observations

William Herschel (c.1784)

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 like the former, but the brightest part in the middle is more joined to the nebulosity than in the former, and the bright part is rather longer, tho' not quite so vivid as in the former. It may still be called cometic, tho' it begins to depart a little from that kind."

Modern observations

Walter Scott Houston

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 . . . M96 is easier to spot than M95. It is about magnitude 9.1 and visible in finders and binoculars. , It is about 4' long and slightly oval in appearance."

Hartung, E.J. (1968) Astron.Obj.South.Tel

Notes: "10.5cm shows it quite plainly. Large instruments disclose a fine elliptical spiral 11' x 8' in pa 150 deg, of which I see with 30cm the brighter inner region 3' x 2'. It is a conspicuous nebula rising greatly in brightness to the centre."

Tom Lorenzin

Lorenzin, in the electronic version of "1000+ The Amateur Astronomers' Field Guide to Deep Sky Observing", notes: "10M; 6' x 4' extent; NE-SW-oriented oblong with very bright center and non-stellar nucleus; very faint mottling apparent with persistent scrutiny !good supernova prospect! see photo at HAG-12."

Ware, Donald J

:"This galaxy is ovoid, 4'x3', extended north-south with a bright core. Its core is large and non-stellar, about 1' in diameter."

1997 March 15. Jonkershoek. 11x80 tripod mounted. No moon. Looking north - light pollution. With attention, seen as round glow. Sky bad!

Alldays (22.50S, 20.12E, 770m).

12-inch f/10 SCT (218x, 346x)

Pretty large, bright and a little irregular, and less than a degree from M95. Faint stars curling around the galaxy to the northwest. A very sudden bright nucleus, with grainy structure, and more round than M95.

12-inch f5 (EP: 26mm SW, 20mm UW, 7mm UW)

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.

Spiral Galaxy located in Leo. Bright, well defined. Fairly low surface brightness. This galaxy has a bright oval shape with the inner regions of the nucleus slightly brighter than M95.The nucleus of this galaxy is well uniformed with a bright central structure.
