This image shows you two minor galaxies lying in northern edge of the Virgo Cluster. They can be found out about 1 degree north from M100. Both have sizes about 3 arc minutes and 12th magnitude in brightness.
The right one is a bared galaxy NGC4340 and left side has a number of NGC4350 classified in lenticular galaxy. NGC4340 has a fairly anomalous shape that the galaxy has a dimmed ring structure surrounding the nucleus. Both galaxies are floating with its interval about 5.5 arc minutes.
