Turn the telescope and hand control ON.

Turn Tracking OFF

Set SPEED to CENTER.
•
Press the right Diamond button until the blinking light changes to 2 times a second. Now the azimuth is in EER.
•
Press the UP button until the light stops blinking. Now both axis are in EER.
•
Move azimuth by hand. Notice the light starts blinking at two times a second again. Now azimuth has been taken out
of EER.
•
Move the altitude by hand and the light will start blinking once per second. Now EER is not activated on either axis.
To center an alignment star, it is good practice to move the telescope by hand until the star is in the field of view. Then,
use the diamond buttons at CENTER speed to center the star. Check to be sure that the light is not blinking. Then press
ENTER to align.
You will notice, whenever the telescope slews to an object, it always finishes the slew in EER. But if you don’t align the
telescope in EER, the accuracy is diminished. You should use a reticle eyepiece to center the alignment stars.
Precise Pointing - Relative Command
This is a more accurate way of pointing the telescope, but takes a little bit longer. If you use the RELATIVE GO TO
command, the computer searches through its database for the brightest star within 5º of the object you are trying to go to.
After the computer locates the star, it will slew to the star. Then you center the reference star. The computer uses this
new information to find the object. Here is how to use the RELATIVE command.
(The telescope must be aligned (on a wedge or Alt-Az) to use the RELATIVE command)
