This image shows you two member galaxies of the Virgo Cluster with an interval of 10 arc minutes lying at about 2.3 degrees west of epsilon Vir. An edge-on galaxy in left is NGC4762 and another right galaxy is NGC4754. The galaxy of NGC4762 is one of well-proportioned edge-on galaxies although smaller than a famous one of NGC4565. NGC4754 has a length of 9 arc minutes and a clear central bulge. This pair cannot be taken an attention because those are positioned in eastern edge of Virgo Cluster, maybe you can enjoy the pair of different shaped galaxies with an interest.
