This program aims at obtaining UVES red spectra of 17 stars in the globular cluster NGC 6752 and two metal--poor field stars for comparison. One rapidly rotating B star (HR 6788) should be observed on each night some of the cluster stars are observed, although P.I. submitted only 5 such OBs: if possible, preference should be given to observing more than one science target per night. No special scheduling requirement. The instrumental setup is always the RED arm centered at 580nm and image slicer #3. All OBs have 3 (concatenated) exposures, for a total of up to 1h30min (not really justified). User has been warned that OBs will not be repeated if constraints are not fulfilled in last 30min of exposure. The expected S/N per exposure around 5120A should be of the order of ~80-100.
