Description:
Interesting pair of contrasting galaxies in Come Berenices near the Virgo
border.
At 98X, NGC 4473 is the smaller and brighter of the two galaxies. It has a very
bright central area and a small and round halo. NGC 4477 is a larger and
fainter, round galaxy with almost no central brightning. Very smooth
appearance in contrast to its neighbor.
