Figure: FORS 1, the FOcal Reducer and low dispersion Spectrograph for the ESO/VLT

General view of the FORS1 astronomical instrument, installed at the Cassegrain focus of UT1. It was mounted here in September 1998 and has since produced a long series of excellent observations, both images and spectra. The second FORS1 commissioning phase was carried out in late December 1998.
