==Recipe for Acquiring a Target==
On the TCS:
 
1. Check that “COORDINATE EQUINOX” is set to that of your target coordinates (otherwise, type it under "SET EQUINOX" and press ENTER on the keyboard).
3. In “Exposures & Guiding”:
* Move GUIDE MIRROR IN BEAM by clicking on that box.
* Adjust the guider exposure time in the grey box next to , and click "Expose"to start images.
* Under “Image Options” select the preferred LUT and SCALE.
* Use the horizontal sliders to adjust the colour scale and the vertical slider to apply gamma correction until stars are easily visible
7. Check the position of the target in the instrument and adjust RA & Dec as necessary using the handset.
8. 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).* Enter coordinates of the field and click "GET IMAGE". A window should appear with a 10x10 arcmin DSS map.* Click on a bright star '''outside''' of the green circle in the DSS image.* Under "XY Slides Control," click "GoTo GS". The star should appear in the acquisition image. If not, try a different star.* Under “Pointer" click "Guide Star" , then click on the chosen guide star in the acquisition camera FOV. This will begin guiding.* 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.
