HOW TO REVERSE THE TELESCOPE

How to reverse the telescope from East to West of the Axis. The reverse operation is carried out by interchanging West for East.

1. Press 'Zenith Park'
2. Turn off TV and Autoguider
3. Close dome, open blind and switch on lights
4. At TCS Console type 'FINISH' This is the furthest VDU from the left of the Telescope Console
5. Switch to engineering Control
6. Turn the speed knobs on the engineering panel to their maximum allowed values. This will be marked against the knobs and may be substantially slower than the maximum physically possible.
7. Watching through the window use the engineering controls to move the telescope to the pole and over the axis. When the telescope reaches the pole carry on turning in Hour Angle until the telescope is well to the West of the polar axis. Continue turning in HA and restart the declination motion in the same direction so that the telescope comes near to the Zenith West of the axis.
8. Return to TCS console and type GO JKT,F15W,COMPILE (F15E if moving from West to East, F8E if observing at f/8. There is no F8W for the present.)
9. When the user-interface appears on the telescope console carry out the zeroset and then switch to computer control.
10. Switch off lights, close blind and open dome.
11. Turn on TV and Autoguider
12. SNAFU
13. Carry on observing; both the TV and CCD displays will appear to have rotated through 180 degrees.
