Looking at or near the
Sun
will cause
irreversable
damage to your eye. Do not point this telescope at or near the
Sun. Do not look through the telescope as it is moving.
Go To Saturn
After performing the Automatic Alignment 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
:
Once aligned, only use the GO TO or Arrow keys to move the
telescope. Do not loosen the telescope locks (
6 and 9, Fig. 1
), or move the base
manually, or alignment will be lost.
Once the telescope is aligned, you may choose and “Go To” any object listed in AutoStar’s
Object menu. This exercise demonstrates how to select one such celestial object, the planet
Saturn, for viewing from the Object menu.
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.
After you Go To Saturn, practice the Go To feature with other objects in the Object menu lists.
For example, during Winter, choose M42, the Orion nebula, from the Messier list. Or in the
summer, choose the Dumbbell nebula from the Deep Sky, Named Objects list.
Using the Guided Tour
This example demonstrates using “Tonight’s Best” Guided Tour.
1. After observing Saturn, press MODE twice so that “Select Item: Object” displays again.
2.
Press the Scroll Down key twice. “Select Item: Guided Tour” displays.
3. Press ENTER. “Guided Tour: Tonight’s Best” displays. Press ENTER.
NOTE:
If you wish to try out other Guided Tours, press the Scroll Down key to scroll
through other tour choices. When the tour you wish to select displays, press
ENTER.
4. “Tonight’s Best: Searching...” displays. After calculating, “Tonight’s Best: Jupiter” displays.
NOTE
: Different objects may be displayed on a tour list on any given night.
Press ENTER to display information about the object. Press GO TO to move the telescope
to the object.
5. Press MODE to return to the Tour list. Press the Scroll keys to scroll through the list. Press
ENTER when you find the next object you wish to observe.
6. Press and hold down MODE for two seconds to leave the Guided Tour menu.
Tip:
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 its search.
(This sometimes
occurs during an
alignment procedure.)
Press GO TO when
the telescope stops
slewing. The telescope
begins to move in a
spiral pattern at a very
slow speed around
the search area.When
the object does
become visible, press
MODE to stop the
spiral search. Then
use the Arrow keys to
center the object.
