Abell 1656, Coma Galaxy Cluster
OK, it's not the Hubble Deep Field I know, but it's about as close as I can get from my garden without a rocket.
And it's definitely worth zooming in on this image. The Coma Cluster (Abell 1656) is a large cluster of galaxies that contains over 1,000 identified galaxies. So, everything in this picture that is not obviously a star is not frogspawn as some have said, but actually a galaxy that is so far away that its light has left on its journey, at 186,000 miles per second, well before the dinosaurs really got going on Earth. Along with the Leo Cluster (Abell 1367), it is one of the two major clusters comprising the Coma Supercluster. It is located in and takes its name from the constellation Coma Berenices.
The cluster's mean distance from Earth, and from my garden, is a frankly amazing 321 million light years. So it is nearly five times further away than Makarian's Chain, and 140 times further than the Andromeda Galaxy. Its ten brightest spiral galaxies have apparent magnitudes of 12–14 . The central region is dominated by two giant elliptical galaxies: NGC 4874 and NGC 4889. The cluster is within a few degrees of the north galactic pole on the sky. Most of the galaxies that inhabit the central portion of the Coma Cluster are ellipticals. Both dwarf and giant ellipticals are found in abundance in the Coma Cluster.
