Description

This is the complete field from this

Messier 51 in LRGB + H-alpha.

The only cluster of galaxies wich I could found in a catalog is Zwicky 6057 with PGC2293576 ( = LEDA 2293576) as it's brightest member, left below the brightest blue star.

Simbad gives the redshift z = 0.15895 and this means a light travel time of 1.9 Gyr. and a "comoving radial distance" of 2.05 Gyr.

The object with the greatest distance is the Quasar J133004.8+472301 with z = 2.847 and a light travel time of 11.42 Gyr - if calculated for a "flat" unsiverse (http://www.astro.ucla.edu/~wright/CosmoCalc.html).

As examples for a Cluster of Stars we can see [HL2008] 117061 with V = 22.531 mag and [HL2008] 112533 with V = 22.689 mag

There are many other galaxies in groups ore clusters - hope you enjoy ;-)
