A small-sized elliptical around the central region of Virgo Cluster is M89. The galaxy is lying about 1.2 degrees apart from a radio galaxy of M87 in east. And it has an apparent diameter of about 5 arc minutes, telescopes can show you M89 as a dimmed light spot. Another spiral galaxy of M90 is positioned about 40 arc minutes north of the galaxy, you can detect those galaxies in same field of view with low magnifying power, and it may be interesting to compare the differences of those shapes.
