Abell 426 (Perseus galaxy cluster  and Perseus A).  Most of the galaxies in the cluster are about 250 million ly distant but the image also includes a few lying a well over 1 billion ly.  Perseus A (bright left of center) is a spiral galaxy 230 million ly away, about the size of the Milky Way. It is a strong radio and X-ray source and appears to be severely distorted by interaction with a passing galaxy in front of it.
