Observation Notes:<\/b><\/p>\n

This was a great pair to observe. M85 had a stellar core and was mildly elongated at a PA of about 25 degrees and appeared to be about 4 x 3 arc minutes in size. A star was embedded just northeast of its core. NGC 4394 was about 7 arc minutes to the east-northeast and also had a stellar core. Its circular profile was adorned with a bar positioned at a PA of 140 degrees. It appeared to be about 2.5 arc minutes in diameter.<\/p>\n

A cursory look at the DSS image shows M85’s outer profile to be aligned almost exactly north-south. However, examining this and other images<\/a> further suggests that the brighter, inner portion of the galaxy is elongated to the northeast as I noticed in this observation.<\/p>\n

Object Information:<\/b><\/p>\n

Galaxy M85 is about 125,000 light years in diameter and 60 million light years away. Although originally classified as a lenticular S0 galaxy, deep exposures show indications of spiral structure. Apparently, the foreground star northeast of the core has repeatedly been mistaken for a supernova. M85 is paired with barred spiral NGC 4394 about 8 arc minutes to the east. Both galaxies are receding at 700 m\/sec which suggests that they are physically paired.<\/p>\n

M85 was discovered in 1781 by Pierre Méchain, and is also cataloged as UGC 7508, MCG+03-32-029, VCC 798, PGC 40515, h 1242, GC 2946, CGCG 099.045, KCPG 334A.<\/p>\n

NGC 4394 was discovered by F.W. Herschel in 1784 and is also catalogued as UGC 7523, MCG+03-32-035, VCC 857, PGC 40614, H II-55, h 1251, GC 2957, CGCG 099.047, KCPG 334B, IRAS 12234+1829.<\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
