18. The telescope slews and “Press V until it is
centered” displays. Press the Down Arrow key until
the target is centered again. Then press ENTER.
“Train Drive: Alt/DEC Train” displays again. You
have now completed this procedure. Press the
MODE key several times until the display reads
“Select Item: Object”.
Advanced alt/az Alignment
If you would rather choose your own alignment
stars from the AudioStar database during the alt/az
alignment procedure, AudioStar offers two methods
described below.
Two-Star alt/az Alignment
Two-Star Alignment requires some knowledge of the
night sky. AudioStar provides a database of bright
stars and two stars from this database are chosen by
the observer for alignment.
A detailed step-by-step description can be found in the
“Easy” alignment description on page 26
One-Star alt/az Alignment
One-Star Alignment requires some knowledge of the
night sky. AudioStar provides a database of bright
stars. One-Star Alignment is identical to Two-Star
alt/az: Alignment (see “Two-Star ETX/AZ Alignment,”
above), except only one star from this database is
chosen by the observer for alignment.
IMPORTANT NOTE : The accuracy of One-
Star alt/az Alignment, unlike the Two-Star and
Easy (alt/az) 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 (Page 29, Fig.
36). Because the other methods use two stars
to align upon, they are more precise than One-
Star Alignment.
Browse
This menu allows you to search the database for objects
with certain parameters, much like a search engine.
“Edit Parameters” lets you set various parameters for
the search, and “Start Search” activates the search. A
typical search might be performed as follows:
1. Select “Browse” from the Object menu. Press
ENTER. “Browse: Start Search” displays.
2. Press one of the scroll keys and “Browse: Edit
Parameters” displays. Press Enter.
3. “Edit Parameters: Largest (mins)” displays.
“Mins” stands for arc-minutes

AudioStar Operation
Too Much Power?
Can you ever have too much power? If the
type of power you’re referring to is eyepiece
magnifi cation, yes, you can! The most
common mistake of the beginning observer
is to “overpower” a telescope by using high
magnifi cations which the telescope’s aperture
and atmospheric conditions cannot reasonably
support. Keep in mind that a smaller, but bright
and well-resolved image is far superior to one
that is larger, but dim and poorly resolved (see
Figs. 44a and 44b below). Powers above 400X
should be employed only under the steadiest
atmospheric conditions.
Most observers should have three or four
additional eyepieces to achieve the full range of
reasonable magnifi cations possible with the LX80
telescopes. See OPTIONAL ACCESSORIES,
Page 52.

magnifi cation and too much magnifi cation.
