M49 (NGC 4472, Arp 134 and others) is the large elliptical galaxy on the right edge of the image. Scientists estimate that it has over 5,900 globular clusters. It is interacting with UGC 7636, the small dwarf irregular galaxy just below and to the left (east) of it. M49 is located approximately 56 million light-years away in Virgo.

NGC 4535 (UGC 7727 and others) is the nice spiral on the left side of the image.

Other larger galaxies include NGC 4526 (bottom left), NGC 4519 (top left) and NGC 4469 (top right).
