which you are familiar from this database when first trying out this method or the One-Star
Alignment method.
One-Star Alt/Az Alignment
One-Star Alignment also requires some knowledge of the night sky. One-Star Alignment is
identical to Easy: Align (see
EASY (TWO-STAR) ALIGN
, Pg. 17), except Audiostar displays a
database of bright stars and
one star is chosen by the observer from this database for
alignment.
IMPORTANT NOTE: The accuracy of One-Star Alt/Az Alignment, unlike the Two-
Star Alignment procedures, depends on how well the observer levels the telescope
and how close to North the telescope is pointed when setting the Home Position
(Fig. 16). Because the Two-Star Alignment methods use two stars to align upon,
they are more precise than One-Star Alignment.
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
:
Once aligned, only use GO TO or the Arrow keys to move the
telescope. Do not loosen the telescope locks (10F, Fig. 1b and 26, Fig. 1), or move
the base manually, or alignment will be lost.
This exercise shows how to select a object (Saturn) for viewing from Audiostar’s database.
NOTE: Saturn is not visible all the time and you may need to choose another object
from Audiostar's Object database; however, the procedure, as described below,
remains the same; just choose a different object in step #3.
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 and Astronomer Inside audio begins to play for the
selected object. On the AudioStar display "Saturn" displays and a set of coordinates
displays. Note that Saturn's (and other planets) coordinates change throught 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 centre Saturn precisely in the eyepiece. Audiostar then
automatically moves the telescope so that it "tracks" Saturn (or whatever other object you
may have chosen);
i.e., Saturn remains centred in the eyepiece.
Take a 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 and listen to the audio presentation
provided by Astronomer Inside. 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 exit the Guided Tour menu.

Looking at or near the

will cause
irreversible
damage to your eye. Do not point this telescope at or near the Sun.
Do not look through the telescope as it is moving.
