Introduction and warnings

The acquisition and guide box (JAG) currently used on the JKT features a travelling flat mirror which when in place directs the telescope beam to a high gain TV camera. This is a very powerful system in many senses of the word and so care must be taken in its use. The best way to ensure that you do not damage the TV and what is more get the most out of its facilities is to READ THE REST OF THIS SECTION.


The very high-gain TV camera can be quickly and permanently DAMAGED BY OVER-ILLUMINATION. Do not, therefore, operate the TV until you have read all of this Section and preferably have also been shown how to use it.
