This image shows you two medium-sized galaxies located in the southwestern part of the Virgo Cluster. The lenticular galaxy at the bottom of the image is NGC4526. It stretches roughly in an east-west direction and is about 7 arc minutes long. If you observe it with a large telescope, you can see a thick dark band running around the central nucleus.
NGC4535 is a spiral galaxy located 30 minutes north of NGC4526. Its apparent diameter is 7 arc minutes, almost the same as NGC4526, and its brightness is 10th magnitude. You can see widely opened two distinct arms are wrapped in an S shape.
