We describe efforts to equip the Southern African Large Telescope (SALT) for precision radial velocity (PRV) work. Our current focus is on commissioning the high-stability (HS) mode of the High-Resolution Spectrograph (HRS), the mode intended to supp

A threat to all telescopes is possible condensation on its instruments and primary mirror during high humidity conditions. Using too conservative delta dew-point control limits for telescope closure can reduce valuable observing time. SALT recently c

The SALT Tracker was originally designed to carry a payload of approximately 1000 kg. The current loading exceeds 1300 kg and more instrumentation, for example, the Near-Infrared (NIR) arm of the Robert Stobie Spectrograph (RSS), is being designed fo
