1. Switch ON '''lighting circuits''' at entrance to dome.
2. Switch OFF all downstairs & observing '''floor lights''' ([http://topswiki.saao.ac.za/index.php/19m74"_/_1.9m#Light_switches having trouble finding the switches]?)
3. Check weather on the [http://suthweather.saao.ac.za/ Sutherland weather website] -- '''only proceed if windspeed < 60 km/h; humidity <90%; T_external - T_dewpoint > 1.5.'''
12. '''End of run''': copy data; report [https://faultreports.saao.ac.za/ faults]; complete [ http://www.saao.ac.za/science/observing/feedback/ feedback form], put Sutherland Observing Record in tray in warm room; for SpUpNIC or GIRAFFE, tear out 1st and 2nd copy of each completed page in triplicate log book -- keep 1st copy and put 2nd copy in end of run tray.
 
==Instrument Focus settings==
Approximate focus values for each of the instruments are listed here. Make further adjustments on target.
GIRAFFE: ~2090
HIPPO: ~2120
SHOC" ~1900 (~1940 with focal reducer)
SpUpNIC: ~2200
STE3/4: ~2090 (~ 2120 with focal reducer)
==Recipe for Acquiring a Target==
7. Check the position of the target in the instrument and adjust RA & Dec as necessary using the handset.
8. Adjust focus, using the TCS Menu1, Focus box (enter value) or the Focus In and Out buttons on the warm room paddle. [([http://topswiki.saao.ac.za/index.php/74"_/_1.9m/#Instrument_Focus_Settings Approximate focus values] are given for each instrument. 9. Once the star is well positioned on the science detector, select a guide star.
* Ensure that XY slides have been initialized. (Click "Initialize" under XY slides control).
* Open the guide star software (the icon of a star with a long tail).
* To stop or restart guiding (e.g. after brief intervals of cloud), press GUIDE.
* To change exposure times, press STOP, update the exposure time in the grey box, and press Expose.
