This elliptical galaxy in Virgo was discovered by Messier on March 18, 1781. Located near the centre of Virgo cluster some 55 million ly away, it measures 100,000 ly across. M84 marks the begining (or W end) of Markarian's Chain - a string of bright galaxies crossing the center of Virgo Cluster. M84 is visible 16' W of M86 in the same low power field (see Virgo Cluster Map and the detailed chart below).
The above image was taken on December 18, 1998 from Sooke, BC. Cookbook 245 LDC CCD camera was used on Celestron Ultima 8 f6.3 telescope autoguided with Cookbook 211 LDC CCD camera on piggybacked 500mm f8 telephoto lens. Six white integrations (240 sec. each) were processed with AIP4WIN.
