Galaxies NGC 2329, UGC 3696, MCG 8-13-72
Galaxy Cluster Abell 569

Galaxy Cluster Abell 569:

The Kopernik image above only covers the central portion of Abell 569, which is a cluster of galaxies in Lynx. There are about 10 galaxies in the Kopernik image, and most are members of this cluster. Abell 262, like most galaxy clusters, has a central X-ray source.

Using the red shift data from the “NASA Extra-galactic Data Base(NED)”, (and a Hubble Constant of 62 Km per sec., per Megaparsec), one can calculate a rough distance estimate for this Galaxy Cluster of about 305 million light years.

Elliptical Galaxy NGC 2329:

NGC 2329 is the brightest galaxy in Abell 569. Although usually classified as a Lenticular Galaxy, recent studies have concluded that it is a 'cluster dominant' Elliptical Galaxy (refer to NGC 708). It is an x-ray source and a radio jet streaming from its core, like many other cluster dominants. In addition that is also a 'radio tail' extending from this galaxy.

Galaxies MCG 8-13-72, UGC 3696, and others:

There are about 10 galaxies in the Kopernik picture of the center of Abell 569, all with about the same red shift, and are thus likely cluster members. Most are dwarf ellipticals. However, MCG 8-13-72 is a spiral galaxy, and UGC 3696 is a large Elliptical Galaxy. There are many more similar galaxies just outside of the Kopernik image field of view.
