Messier 100 (also known as NGC 4321) is a mag 10.1 face-on spiral galaxy located in the southern part of the constellation of Coma Berenices. It is one of the brightest and largest galaxies in the Virgo cluster and is located approximately 55 million light-years from Earth. The nice edge-on galaxy to the right in my image is NGC 4312. Another small spiral galaxy can be seen to the left of M100 - NGC 4323, and there is an elliptical galaxy, NGC 4328 below M100. IC 783 is at the top, and there are other assorted PGC galaxies spread around this rich area.
