Cluster of Galaxies-1ESO657-55
Colour composite image of the galaxy cluster 1ES 0657-558, based on data taken in the B (blue; exposure 900 sec), V (green; 600 sec), R (red; 500 sec) and I (near-infrared; 600 sec) filters with FORS1 in the standard observing mode at the VLT UT1. A few of the brighter stars in the field saturated the CCD during the exposure; their images have been cleaned in this reproduction. North is up and East is left.
