R.A./DEC Reverse
As mentioned previously, the direction a particular button moves the mount varies depending on the telescope’s orientation (i.e., whether it’s on the east or west side of the mount). This can create confusion when guiding if you change the telescope’s orientation during a given photographic session. To compen- sate for this, the direction of the R.A. and DEC buttons are changeable. To reverse the direction of either the R.A. and/or DEC buttons, change the switch setting of the appropriate axis (see Figure

Autoguiding
On the top side of the hand controller you will find a phone jack outlet desig- nated for use with an autoguider. Most CCD autoguiders will require a cable that attaches the autoguider to your telescope's drive controller via the hand controller outlet, rendering the hand controller inoperable. By plugging the autoguider cable directly into the hand controller, you have the ability to override the autoguider and make manual corrections with the hand controller buttons.
