/* TCS Recipe for Acquiring a Target */
You can cancel the '''Auto Request''' at any time by pressing the '''Manual''' button or even the '''STOP Tel.+Dome''' button. The '''STOP Tel.+Dome''' button will put the telescope in a safe mode
3. In <big>'''Exposures & GuidingIdentify the target'''</big>In'''Exposures & Guiding''':
* Move '''GUIDE MIRROR IN BEAM''' by clicking on that box.
* Click '''Expose''' and select exposure time from drop-down menu to start images.
* '''Hint ''' for good scaling in the display: keep the bottom slider all the way to the left and move the top slider towards the left until the stars appear. Then adjust the vertical slider. Dragging downwards generally reduces background and increases contrast. 4. <big>* '''Identify the target'''</big> in the image display by comparing to a finder chart and making fine adjustments in RA & Dec using the handset or the TCS GUI handset. 5. * Place the target at the location on the image display corresponding to the desired position on the<big> '''science instrument'''</big>.
* Ensure that XY slides have been initialized. (Click "Initialize" under XY slides control). This should have been done before acquiring target.
Note the next steps are generalizations. Details may vary depending on the instrument being used.
* Once focus is achieved for the instrument, the guider camera may need to be refocussed. Under the "Camera Focus" box at lower right, click on the up/down arrows to start focus changing. Press stop to stop the change.
* Enter coordinates of the target field in the guide star software and click '''GET IMAGE'''. A window should appear with a 10x10 arcmin DSS map. In order to save time, this step could have been done earlier whilst telescope was slewing.
* Click on a brightish star ''outside'' of the green circle in the DSS image.
