AudioStar and the telescope without forgetting its
alignment. With “Sleep Scope” selected, press
ENTER to activate the Sleep function. AudioStar goes
dark, but the internal clock keeps running. Press any
key, except ENTER, to re-activate AudioStar and the
telescope.
Park Scope is designed for a telescope that is not
moved between observing sessions. Align the
telescope one time, then use this function to park
the telescope. Next time it is powered up, enter the
correct date and time – no alignment is required.
Pressing ENTER causes the telescope to move to
its pre-determined Park position. Once parked, the
screen prompts to turn off power.
Important Note: When the “Park Scope” option is
chosen and the display prompts you to turn off the
telescope’s power, AudioStar is unable to be returned
to operation without turning the power off and then
back on.
Language: Select the English language or other pre-
loaded language and AudioStar will display text and
audio descriptions in the selected language.
Cord Wrap, when set to “On”, moves the telescope
in such a way as to prevent the cords and cables
attached to your telescope assembly from getting
wound around the assembly and tangled as the
telescope slews to objects. “Off” is the default setting.
Audio Clip: Select from Automatic or On Demand.
The Automatic setting will automatically play the
object audio when a night sky object is selected on
the AudioStar. The On Demand feature requires the
user to press the ? key once a night sky object is
selected. Pressing the ? key will then play the audio
presentations for the selected object.
Setup Menu
The Setup menu’s primary function is to align the
telescope. However, there are numerous other
features available within the Setup menu, including:
Date changes the date used by AudioStar. Always
make sure the date is correct in AudioStar before
beginning. This function can also be used to check
events in the past or future. For example, set the Date
menu for a day three months in the future. Then check
the “Select Item: Event” menu for the Sunset time on
that date.
Time changes the time entered into AudioStar.
Setting the correct time is critical for AudioStar to
properly calculate locations and events. Always make
sure the time is correct in AudioStar before beginning.
Time may be set to 24-hour mode (military time) by
selecting the “blank” option which follows the “AM” and
“PM” options.
Daylight Saving is used to enable or disable Daylight
Savings time.
Note: Daylight Savings Time may be referred to by
different names in various areas of the world. Check
local time to verify.
Telescope accesses the several options, including:
• Model: Allows you to select the telescope model
connected to AudioStar.
• Focal Length: Displays the focal length of the
selected telescope.
• Az Ratio and Alt Ratio: The Az (Azimuth) ratio
and Alt (Altitude) ratio refers to the gears of the
telescope’s motors. Do not alter these numbers.
• Az Percent: The Az (Azimuth) Percent allows
you to change the azimuth backlash, i.e., the
way the Arrow keys move the telescope along
the azimuth (horizontal) axis. If you enter a value
near 100, the telescope tube responds more
quickly (it responds immediately at 100%) as you
hold down an Arrow key and also slews (moves)
the tube more quickly. If you enter a value near
0, it takes longer for the tube to respond as you
hold down an Arrow key and also slews the tube
more slowly. Experiment with this option. Try
changing the percent value until you get a “feel”
for the Arrow keys that is comfortable for you.
• Alt Percent: The Alt (Altitude) Percent operates
identical to the Az Percent option (see above),
but allows you to change the altitude backlash,
i.e., the way the Arrow keys move the telescope
when moving along the altitude (vertical) axis.
• Train Drive: Trains the Altitude and Azimuth
motors to locate objects with more precision.
If you are experiencing any problems with pointing
accuracy, follow the procedure described in
APPENDIX A: TRAINING THE DRIVE, page 42,
to insure accurate pointing and tracking.
