These elliptic galaxies are positioned around center of the Virgo Cluster paralleling only 17 arc minutes in interval. Right and left ones in this picture have the Messier's numbers of M84 and M86, respectively. Both look like simple dimmed lump of light without any striking structures.
Those galaxies are positioned at the western edge of a famous galactic line, the Markarian's chain that is formed from ten or more galaxies. You can detect many faint galaxies around this field.
