* '''Dome lockout switch''' beside the dome control console at the North end of the pier. '''Note that this does not lock out the telescope, only the dome.''' Lockout should be switched on (a red light on the box will flash) if people are working on the dome, otherwise left off.
=== The Telescope ===
Lesedi is a 1-metre Alt-Az Ritchey-Chretien telescope. There are two Nasmyth foci, each with an instrument rotator and identical corrector optics. The Nasmyth ports are identified as left and right, defined from the point of view of someone standing behind the parked telescope, i.e. looking at the back of the primary mirror cell. SHOC is mounted on the right-hand port, and Sibonise will be commissioned on the left in the near future. Future instruments (a low-resolution spectrograph and a fibre-fed echelle) will be co-mounted on an instrument selector to share the right-hand port with SHOC. A motorised tertiary mirror allows an instrument on either port to be selected in seconds.
The telescope is parked facing East, the dome to the West. There shouldn't be any need for manual interaction with the telescope during the night, but you should ensure that the observing floor is clear of ladders and other obstacles before moving the telescope, and that the mirror covers are closed before opening the dome.
