Galaxy cluster in the Capodimonte Deep Field

This is an enlargement of a galaxy cluster of the Capodimonte Deep Field, which most members are located in the north-east quadrant (upper left) and have a reddish colour. The nebulous object to the upper left is a dwarf galaxy of spheroidal shape. The red object, located near the centre of the field and resembling a double star, is very likely a gravitational lens. Some of the very red, point-like objects in the field may be distant quasars, very-low mass stars or, possibly, relatively nearby brown dwarf stars. The field shown covers 1380 x 1630 pixels, or 5.5 x 6.5 arcmin 2.

Technical information: this image displays selected areas of the field shown in ESO Press Photo eso0116a at the original WFI scale, hereby also demonstrating the enormous amount of information contained in these wide-field images. North is up and East is left.
