Distant Cluster of Galaxies

April 28, 2005
This photo is reproduced from a 5-min near-infrared exposure, also obtained during the night of First Light of the FORS1 instrument (September 15, 1998). It shows a sky field near the quasar PB5763 in which is also seen a peculiar, quite distant cluster of galaxies. It consists of a large number of faint and distant galaxies that have not yet been thoroughly investigated. Many other fainter galaxies are seen in other areas, for instance in the right part of the field.

This cluster is a good example of a type of object to which much observing time with FORS will be dedicated, once it enters into regular operation.
