A lenticular galaxy in northeast edge of the Virgo Cluster is NGC4710. The galaxy has a long axis of 5.6 arc minutes and 12th magnitude in brightness. It's not so striking one but has a typical edge-on figure; you can see a well-proportioned spindle shape through telescope-aided eyes. This picture has captured irregular-shaped but dimmed dark lanes around the central bulge.
