of how AudioStar’s keys operate.
Hint:
It is best to verify the AudioStar's site
information before performing any night sky
alignment. Check the date, time, daylight
savings, location, and telescope model before
each alignment. If any of these are incorrect,
the ETX will not operate correctly.
How to perform the Easy Align
Procedure
If you have just powered on the telescope, follow
the procedures listed in “Initializing AudioStar” on
page 11. When completed, continue on to the steps
below to perform the Easy Alignment procedure. If the
telescope is already powered on and the correct site
location, date, time, daylight savings, and telescope
model have already been entered, the Easy Alignment
can be started by selecting in the menu Setup: Align:
Easy and following the steps below.
1.
When the Easy Alignment procedure is
selected in the AudioStar’s setup menu. See
page 9, “The ETX Alt/Az Home Position” for a
description on placing the ETX telescope into
the home position.
Note:
The easiest way to set the telescope in
the home position is using the Magnetic North
method. Follow the steps on page 10 “Finding
Magnetic North using a Compass.
2. Star Alignment -
The AudioStar then chooses
two stars to align upon. When the telescope

the Arrow Keys to move the telescope to place
the red dot on the top of the brightest nearby
star. Now look through the eyepiece and use

If that area of the sky is obscured by an
object, you can prompt AudioStar to chose an
alternate star by pressing either one of the two
Scroll Keys. Repeat procedure for the second
alignment star.
When the procedure is performed correctly, “Alignment
Successful” displays. If AudioStar does not display this
message, perform this procedure again.
Note:
AudioStar locates alignment stars based on the
date, time, and location entered. The alignment stars
may change from night to night. All that is required is
for the observer to precisely center the selected stars
in the eyepiece when prompted.
Hint:
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

search. (This sometimes occurs during an alignment

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.
