These galaxies are positioned at the most eastern region of the Virgo Cluster in all member galaxies with Messier's numbers. You can catch these galaxies as two dimmed lights around five degrees west of epsilon Virginis. Galaxies on the right and left hand sides are M59 and M60 respectively. And M60 has small companion spiral galaxy of NGC4647 just north west of it. Both galaxies are simple elliptic, so they show you only nebula like images, and it can be realized that M59 is a bit stretched in north-south direction.
