NOTE: The GO TO key also allows you to perform a "spiral search." A spiral search
is useful when the telescope slews to an object, but that object is not visible in the
eyepiece after the telescope finishes it search. (This sometimes occurs during an
alignment procedure.) Press GO TO when the slew is finished and the telescope
starts slewing in a spiral pattern at a very slow speed around the search area. Look
through the eyepiece and when the object does become visible, press MODE to
stop the spiral search. Then use the Arrow keys to center the object.

Go To Saturn

After performing the Easy Align procedure, the motor drive begins operating and the telescope
is aligned for a night of viewing. Objects in the eyepiece should maintain their position even
though the Earth is rotating beneath the stars.
IMPORTANT NOTE
:
telescope. Do not loosen the telescope locks (6 and 9, Fig. 1), or move the base
manually, or alignment will be lost.
This exercise demonstrates how to select a celestial object, the planet Saturn, for viewing from
Autostar's database.
NOTE: Saturn is not visible the entire year and you may need to choose another
object from Autostar's database; however, the procedure, as described below,
remains the same.
1
After the telescope is aligned, "Select Item: Object" displays. Press ENTER.
2.
"Object: Solar System" displays. Press ENTER.
3.
"Solar System: Mercury" displays. Keep pressing the Scroll Down key until "Solar System:
Saturn" displays.
4.
Press ENTER. "Calculating" displays. Then "Saturn" and a set of coordinates displays.
Note that Saturn's (and other planets') coordinates change throughout the year.
5.
Press GO TO. "Saturn: Slewing..." displays and the telescope slews until it finds Saturn.
You may need to use the Arrow keys to center Saturn precisely in the eyepiece. Autostar
then automatically moves the telescope so that it "tracks" Saturn (or whatever other object
you may have chosen); i.e., Saturn remains centered in the eyepiece.
