W
Reverse L/R: Reverses the functions of the Left and Right Arrow keys for
controlling the telescope’s motion (
i.e.
, the Right key moves the telescope to the
left
).
W
Reverse U/D: Reverses the functions of the Up and Down Arrow keys for
controlling the telescope’s motion (
i.e.
, the Up key moves the telescope down
).
W
Home Sensors: Turns off or on the True North and True Level sensors, if
preferred, for Easy, One-Star, and Two-Star alignment. User must then manually
level the telescope and point the telescope to True North during alignment.
Default setting is “On”.
W
GPS Alignment: GPS: Select “Off” to turn off the GPS function—you will be
prompted to manually enter the time, date and location. Select “Start Up” to have
the GPS function begin when you turn on A u t o S t a r. Select “When Needed” to have
the GPS function begin only when it’s needed. For example, you have not
performed the GPS fix yet and you have select Sunrise. AutoStar needs to know
time, date and location to calculate Sunrise times, so the GPX fix will begin when
you select press ENTER after selecting Sunrise.
W
Dec. PEC: Allows you to perform periodic error correction on the Dec. drive worm
gear. Must be performed with a high-power reticle (
eg.,
9mm).
W
R.A. PEC: Allows you to perform periodic error correction on the R.A. drive worm
gear. Must be performed with a high-power reticle (
eg.,
9mm).
W
High Precision: If High Precision is turned on, when looking for a faint celestial
object (
e.g.
, a nebula or galaxy), AutoStar II first slews to a nearby bright star and
displays “ENTER to Sync”. Center the star in the eyepiece, then press ENTER.
At that point the telescope has a high precision alignment to that part of the sky
and it then slews to the object that was originally requested.
Targets: Switches between Astronomical targets and Terrestrial targets. If
“Astronomical” is selected, the telescope tracking motor is activated and any object
you observe will remain centered in the eyepiece. If “Terrestrial” is selected, the
tracking motor is turned off. See
TO TRACK AN OBJECT AUTOMATICALLY
, page 19.
Site provides access to several options including:
W
Select: Displays the currently selected observing site. Use the Scroll keys to
cycle through all available sites (see
ADD
below). Press ENTER when the site
you wish to select displays. Use this option when you move to a different
geographic location.
W
Add: Allows you to add new observing sites to the database. Scroll through the list
of Countries/States. Press ENTER when the site you wish to add displays. T h e n
choose the desired city in the same manner.
H o w e v e r, when the GPS signal is received, the site is normally selected

necessary and is included for the convenience of those users who may wish to
enter a site manually. You may edit the name of a site using the Edit option
(see below).
W
Delete: Deletes a stored site from the database.
W
Edit: Edits a selected site, including: the name, latitude, longitude, and time
zone. Time Zone refers to the Greenwich Mean Time (GMT) time zone shift.
Users West of Greenwich, England use “-” hours, East of Greenwich use “+”
hours. For the United States, look up the time zone shift in Table 1.
Note: AutoStar II compensates for daylight savings time, if selected. See
SETUP MENU: DAYLIGHT SAVING
, page 29.

Important Note:
The Site information is
stored in the Site menu. If
you move the telescope
outside of a 5 miles area of
your initial observing
location, AutoStar II
automatically determines
your location when it gets a
GPS Fix, and adds the new
location to the Site menu.
