Most of the galaxies visible in this Hubble image are members of a huge cluster called CLASS B1608+656, which lies about 5 billion light-years away. But the field also contains other objects that are both significantly closer and far more distant including two gravitational lenses dubbed Fred and Ginger. ... Fred, also known more prosaically as [FMK2006] ACS J160919+6532, lies near the lens galaxies in CLASS B1608+656, while Ginger ([FMK2006] ACS J160910+6532) is markedly closer to us. ...
