Category: External galaxy.
Data: mag 8.6 size 7'.2 x 6'.8
Position: RA 12:30 DEC +12:24
Gigantic elliptical galaxy at the heart of the Virgo cluster of galaxies.
Just south of a mag. 8.5 star M87 is a very large and very bright round
elliptical galaxy easily seen at 49X. At higher powers M87 appears with a
bright nucleus and a outer halo that gradually gets fainter outwards.
Otherwise no details were seen.
About 8' away is the rather faint and small round galaxy NGC 4478 which has
a bright center. NGC 4478 was well seen at 98X and 203X.
