This image shows you galaxies scattered about 8 degrees northeast of β Vir.
The largest elliptical galaxy, NGC4261, is located at the southern edge of the Virgo cluster and has a major axis of just over 4 arc minutes.
Most of the 15 or more galaxies in this image are distributed in the outer edge of the Virgo Cluster, but NGC4273, for example, in the lower part of the image is located 130 million light years away,
and some of them don't belong to the cluster.
In addition, a more distant galaxy cluster Abell 1516 can be seen in the lower right corner of the image.
