The Hand Control The hand control is located on the side of the fork arm and can be removed and used remotely or used while attached to the fork. The hand control attaches to the fork arm by resting on two posts, located on the bottom of the hand control cradle, and a clip inside the fork arm. To remove the hand control from the fork arm cradle, gently lift the hand control upwards and pull out. To return the hand control into the fork arm, lower the hand control into the cradle so tha

The Star Pointer Finderscope The Star Pointer is the quickest and easiest way to point your telescope exactly at a desired object in the sky. It's like having a laser pointer that you can shine directly onto the night sky. The Star Pointer is a zero magnification pointing tool that uses a coated glass window to superimpose the image of a small red dot onto the night sky. While keeping both eyes open when looking through the Star Pointer, simply move your telescope until the red dot,

3. With both eyes open, look through the glass window at the alignment star. 4. If the Star Pointer is perfectly aligned, you will see the red LED dot overlap the alignment star. If the Star Pointer is not aligned, take notice of where the red dot is relative to the bright star. 5. Without moving the main telescope, turn the Star Pointer's azimuth and altitude alignment controls until the red dot is directly over the alignment star. If the LED dot is brighter than the alignment star,

In order to accurately center the alignment star in the eyepiece, it may be necessary to decrease the slew rate of the motors for fine centering. This is done by pressing the RATE key (11) on the hand controller then selecting the number that corresponds to the speed you desire. (9 = fastest , 1 = slowest).

1. Press the INFO Key. This will give you useful information about the selected object such as R.A. and declination, magnitude and most importantly, altitude above the horizon. (If a star alignment has not yet been performed, the altitude will not be displayed). The speed at which information scrolls across the hand control display can be changed while the information is being viewed: • Hold down the “1” key to speed up the scroll speed. • Hold down the “4” key to slow down th

The hand control has a "double button" feature that allows you to instantly speed up the motors without having to choose a speed rate. To use this feature, simply press the arrow button that corresponds to the direction that you want to move the telescope. While holding that button down, press the opposite directional button. This will increase the slew rate to approximately 1º per second (equal to rate 7 on the hand control). This feature will not function if the telescope is currently s
