/* Acquiring a target */
== Acquiring a target ==
# Follow the facility [[#Start-up recipe|start-up procedure]].
# Check that the selected target is within the [[#Telescope pointing limits|observing limits]].
# Set "Exp Time" to ~2-4s and "WINDOW" to "Full frame" to take images with the acquisition camera.
# Use the hand paddle for fine adjustment of the telescope to the target's coordinates while watching the image display for the target field to appear. Comparison with an 8x8 arcmin finderchart is most helpful.
 # The position should be accurate if you have followed [[#Determining pointing offsets using a bright star|this procedure]], so check your zeropoints. If not, adjust "Exp Time" to search for patterns in fainter stars to compare with your finderchart. If this fails, then reduce the exposure time and scan the field by systematically adjusting RA & Dec. 
# Once the target is identified, position it on the image display such that it falls on the centre of the science CCD.
