| * Moving the joystick will send commands to the controller to move the telescope. In this implementation moving the joystick will result in a single commanded JOG (moving the telescope of a set number of arcminutes). The behavior is NOT as is customary with the paddle moving the telescope continuously while using the joystick (like a remote controlled toy or video game). Holding the joystick in a particular direction will not initiate further motion. The joystick must be permitted to return to the neutral (central) position for another JOG. In addition, a first JOG must be completed with the telescope settling to the new position before another JOG will be possible. | * Moving the joystick will send commands to the controller to move the telescope.

| * The magnitude of the JOG is determined by adjusting the not-currently-well-named //SPEED// knob. Recommended JOG magnitudes for centering in an eyepiece are 1-5. The largest jogs move the telescope a degree or more. If the telescope servos are not tuned properly (or the telescope is out-of-balance) this can be problematic. | * The magnitude of the JOG is determined by adjusting the not-currently-well-named //SPEED// knob.

(It should be possible to hear the brakes clamp down...but in a crowded observatory filled with people this may not be obvious. The E-Stop light on {{: | ||
