Telescope
- Switch off lights on all floors, close the blind in the restroom.
- Check the Operations Logbook for any restrictions.
- Make a visual inspection of the observing floor.
- Put the Telescope in ENGINEERING MODE.
- Clear any emergency overrides.
- Ensure that none of the SELECT MANUAL CONTROLS buttons have been activated.
- Make sure that the TCS/DAS/ICL software is running.
- Turn on OIL PUMP from the engineering rack.
- Move the telescope to ACCESS PARK.
HA synchro pointers at the "12:00", turn DEC QM speed clockwise, push the
DEC QM button, push and hold the DEC [+] button, later turn and hold the
LIMIT keyswitch, push the DEC [+] button until close to 105 degrees.
- Fill the WFC, wear safety helmet (with visor) and gloves when filling
cryostat! Always remember to leave the PRESSURE RELEASE valve on the
dewar OPEN.
- Move the telescope out of ACCESS PARK.
Turn DEC QM speed clockwise, turn and hold the LIMIT keyswitch, push the
DEC QM button, push and hold the DEC [-] button.
- Zeroset encoders.
Check telescope is vertical, HA synchro "12 O`Clock" position and DEC
synchro "9:45" position.
USER>zeroset ha target (or: zero ha tar)
USER>zeroset dec target (or: zero dec tar)
Using the HA and DEC [+]/[-] buttons with slow motion (SM) and very slow
speed, move the telescope so the synchro dial pointers MOVE THROUGH the
"12 O' Clock" position in HA and the "9:45" position in DEC.
- Open up dome top shutter.
Use RAISE MICRO until the OVERTRAVEL indicator goes off, RAISE MAIN until
the shutter stops moving.
- Open up primary mirror cover.
- Switch dome vent fan on.
- Turn off dome lights and close control room blind.
- Switch telescope into Computer Mode.
The HA and DEC slow motion (SM) push buttons MUST be set for SM mode
(i.e. All the lower green sections of the buttons illuminated) and the
oil pump must be on before Computer Mode can be selected.

Observers handover check
Ready to go it alone? Please check you are familiar with the following tasks:
- use of Intercom and Telephone
- safety precautions when using liquid nitrogen
- weather precautions, knowing when the dome must be closed
- observing at zenith distance between 57 and 70 degrees
- opening and closing the dome
- moving the telescope in engineering mode
- starting up and shutting down the observing system
- knowing about the most common faults and how to solve them
- writing your data to tape at the end of every night
- filling in fault reports
- filling in log book in control room
- producing the observing log
- filling in observing feedback form at the end of your run
