M85 is a galaxy around the northern edge of the Virgo Cluster in the constellation of Coma Berenices. Though the galaxy shows you a dimmed elliptic light without clear structures, classified as SO type because of the moderate characteristics between the elliptical and spiral. The galaxy has about 7 arc minutes in long axis and 10th magnitude. It might be needed fairly large telescopes to recognize clear appearances of a galaxy. This picture shows you another dimmed bared galaxy of NGC4394 just east of M85 with 11th magnitude.
