Galaxy Cluster in Perseus

View larger image

The Abell Catalog lists this galaxy group as having 36 members. Many of these can be seen in this image, although others are outside of the field of view. The brightest galaxy of the group, PGC 10473, which is to the upper right of center, is listed in some sources at magnitude 13.7, which means it should be visible in typical amateur telescopes. The other galaxies are dimmer and would be very difficult to see though the eyepiece of even large telescopes.

The redshifts of these distant galaxies suggest that they are about 500 million light years away.
