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.

Go to Zenith Park.

2.

Switch to engineering Control.

3.

Exit the TCS.

4.

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.

5.

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.

6.

Start the TCS for west of pier.

7.

When the user-interface appears carry out the zeroset and then switch to computer control.

8.

Do a CALIBRATE.

9.

Note: both the TV and CCD displays will appear to have rotated through 180 degrees.
