Sketch of Messier 87 (NGC 4486), NGC 4478, NGC 4476

Observation Notes:
Large, bright elliptical galaxy M87 appeared to be aligned at a PA of 100 degrees. It’s core appeared stellar, and it shared the field with 2 other galaxies. The next brightest, NGC 4478 also possessed a bright speck at its core and appeared to line up at a PA of 150 degrees. The third galaxy had a soft, mildly condensed glow, aligned at 45 degrees. A bright yellow star colored the field about 5 arc minutes north of M87. Comparing the sketch to the DSS image below shows that I definitely need to refine my PA estimates on elliptical galaxies.

Object Information:
Lying at the heart of the Virgo Cluster, M87 is likely the dominant member. Its 120,000 light year extension contains several trillion solar masses. It contains several thousand globular clusters and is well known for a 5000 light-year-long jet emanating from a black hole at its core.
M87 was discovered in 1781 by Charles Messier and is also cataloged as NGC 4486, UGC 7654, MCG+02-32-105, ARP 152, CGCG 070.139, h 1301, GC 3035, 3C 274, PGC 41361.
NGC 4478 and 4476 were discovered by F.W. Herschel in 1784. NGC 4478 is also catalogued as UGC 7645, MCG+02-32-099, CGCG 070.133, H II-124, h 1298, GC 3031, VCC 1279, PGC 41297. NGC 4476 is also catalogued as UGC 7637, MCG+02-32-096, CGCG 070.128, H II-123, h 1296, GC 3028, VCC 1250, IRAS 12274+1237, PGC 41255

Supernova M-87 , two rings appears in year 1987 when it knew that nova was explode and form two rings . and it was the first time when hubble space telescope make its photograph. and it was a very big success in science history. when we know about supernova explosion. at first we knew it in tales only when stars broken ( laila and majnoon ). but it was manualy tales and reality is against the tales . but today hubble space telescope is only a story of the past…..from 1984…..to…….1992. but this time from several years im in search of new photographs but nothing happen……. my other email is younus_afridi2004@yahoo.com. and mobile number is 03232077551. code is +92 . thanks for comment box providers.
