/* Acquiring a target */
3(b) In the TCS '''Controls''' tab click '''Catalogue''' '''HOW DOES THIS WORK??'''.
The telescope will slew to the target, and its movement will be plotted in yellow dots on the schematic in the right-hand panel. The "Go" button will become a "STOP" button, which you can click to stop the telescope. Once it reaches the target coordinates, the telescope will start to track and red dots will show the track progress on the visibility plot. If nothing happens, the target is probably out of the observing window - return to step 2.
4. The telescope will track the target until you click '''STOP'''. To run SHOC, follow the instructions on the [https://topswiki.saao.ac.za/index.php/SHOC SHOC wiki].
5. Focus Lesedi's pointing is excellent, so your target should land very close to the telescope using centre of the SHOC image. The '''Adjust Focus...image orientation''' button, which brings up a box with no "flips" applied in which you can enter the focus increment. A reasonable starting point for SHOC focus with a filter in software (check the Advanced tab of the beam SHOC control) is ~2000 - you can check North Up, East to the focus position in left, when the status panel on rotator sky angle is 0, North down, East to the Controls tab. A reasonable increment for small adjustments is ~5right with a sky angle of 180. Clicking '''+Add more about rotation.''' or '''-''' then adds or subtracts 5 microns to the focus position.

To adjust the pointing (e.g. to position a target and comparison star in the field),
