DEFINITION:
Initialization is a
procedure that ensures
that AudioStar operates
correctly. When you
first use AudioStar, it
doesn’t yet know where
the observation location
site is.
During the procedure,
you will enter the
observation location.
AudioStar uses this
information to precisely
calculate the location of
celestial objects (such as
stars and planets) and
to move your telescope
correctly for various
operations.

Looking at or near the Sun 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.

the city and state or country of your observing location). Press Up to select the zip code
option or down to enter the city and state.
Note: The location settings (country/state/province and city, or zip code) are only
asked for the first time you turn on the control panel. If you wish to change this
setting later on, use the Site menu. See SITE, pages 30, for more information.
a. If you chose the zip code option, the leftmost “0” is highlighted. Use the Number
keys to enter the digits. As you enter a digit, the next digit to the right will be
highlighted. Enter the next digit. Repeat this process until all 5 digits of your zip
code are entered. Press ENTER.
b. If you chose the location option, the next screen asks for the country or state/
province (listed alphabetically) of the observing site.
5. Use the Scroll keys to scroll through the list of countries, states, and provinces. Press
ENTER when the correct location displays.
6. The next screen asks for the city (listed alphabetically) closest to the observing site. Use
the Scroll keys to scroll through the list of cities. Press ENTER when the correct city
appears on screen.
7. Daylight Savings Time: The next screen requests the status of Daylight Savings Time.
Press one of the Scroll keys to toggle between the YES/NO settings. When the desired
setting displays, press ENTER.
NOTE: When multiple choices are available within a menu option, the current option
is usually displayed first and highlighted by a right pointing Arrow (>).
8. AudioStar then requests the telescope model number. Use the Scroll keys to cycle through
the database of models. Press ENTER when your model number displays.
9. System initialization is complete. The Easy Alignment feature begins automatically after
the control panel is initialized.
Observe a Star using the Automatic Tracking Feature
In this example, the AudioStar Arrow keys are used to find a star, and then AudioStar’s tracking
capability automatically keeps the star centered in your telescope’s eyepiece.
1. Set in Home Position: Level the optical tube and point it True North. Make sure that the
Altitude Lock (10F, Fig. 1 or 2 b) and tripod base lock knob (17, Fig. 1 or 2) are secured as
described previously.
2. Plug in AudioStar: Make sure the telescope power switch is in the OFF position. Plug
AudioStar into the HBX port of the Control Panel.
3. Turn on AudioStar: Flip the telescope power switch to the ON position.
4. Select Daylight Savings: Set Daylight Savings, if prompted.
5. Select Setup: Align Option: Press MODE (3, Fig. 2). “Setup: Align” displays.
6. Select Setup: Targets Option: Press the Scroll Down key repeatedly until “Setup:
Targets” displays. Press ENTER (2, Fig. 3).
7. Select Targets: Astronomical Option: “Targets: Terrestrial” displays. Press either of the
Scroll keys once (7, Fig. 3). “Targets: Astronomical” now displays.
8. Locate a Bright Star: Use the Arrow keys (5, Fig. 3) to locate a bright star in the night
sky. Use the viewfinder (7, Fig. 1 or 2 ) to help line up on the star. You may choose any
unobstructed, bright star for the purposes of this example. Use AudioStar’s Arrow keys to
center the star in the eyepiece.
9. To Start Tracking: Once the star is centered, press ENTER to select “Astronomical.” The
telescope’s tracking motors then engage. It may take the tracking motors several seconds
to begin tracking. When they do, it may be necessary to once again center the star in the
eyepiece. The tracking motors will then keep the star you have chosen in the center of the
eyepiece.
10. If you wish to track another star, use the Arrow keys to slew the telescope to the star.
Center the star. The tracking motors will then keep that star in the center of the eyepiece.
