Galaxy cluster Zwicky 2350.6+0758
This is a 17 minute exposure with an ST-9E CCD camera thru Kopernik's 20-inch F/8.1 (working at F/4) Ritchey Chretien Cassegrain telescope taken on July 21, 2001 at 6:20 UT. This image is a mosaic of two exposures. The field of view = 16x23 arc minutes with west at the top.

Labeled version

Zwicky 2350.6+0758 is a Galaxy Cluster with six members. One member, 15th magnitude Spiral Galaxy NGC 7780, was the hose of Supernova 2001 da (seen in the image above). The other Galaxies in this cluster include NGC 7778, NGC 7779, NGC 7781, NGC 7782, and MCG 1-60-44.

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 271 million light years.
