{ Quiet Slew: Sets the maximum slew rate to 1.5° for quieter operation.
{ Max Elevation: Allows you to enter a value in degrees that sets a limit as to how far the
optical tube can swing upward during a programmed slew. (Note that it does not prevent
y
ou from performing a manual slew past this limit.) This is useful when you have a camera
or other peripheral attached to the telescope—you can prevent it from striking the tele-
scope base.
{ Min AOS (Acquisition of Signal): Allows you enter a value in degrees. This value repre-
sents the altitude at which your telescope begins to slew when acquiring a satellite track.
This is useful when y
ou are observing satellites, but a tall tree or building is obstructing the
telescope. For example, you might begin to track the satellite at 15° altitude, instead of 5°.
See
OBSERVING SATELLITES, page 29, f
or more information about satellites.
{ Calibrate Motor: If the telescope motors appear to have a problem, use this option to
retest the motors before performing a Reset. This option is also used if an Autostar unit is
moved between telescopes, to match Autostar to the new telescope. To calibrate the
motors, select this option and press ENTER.
{ High Precision: If High Precision is turned on, when looking for a faint celestial object (i.e.,
a nebula or galaxy), Autostar 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 par
t 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 cen-
tered in the eyepiece. If "Terrestrial" is selected, the tracking motor is turned off. To learn how
to track an object automatically, see page 16.
Site provides access to several options including:
{ 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.
{ Add: Allows you to add new observing sites to the database (up to six sites may be stored).
Scroll through the list of Countries/States. Press ENTER when the site you wish to add dis-
plays. Then choose the desired city in the same manner.
{ Delete: Deletes a stored site from the database.
{ 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.

IMPORTANT NOTE:
While performing the
automatic tracking
procedure, only use
the Arrow keys to
move the telescope.
Once the telescope
has been set in the
Alt/Az home position,
do not loosen the
telescope locks (13
and 14,
Fig. 1), or
move the base
manually, or alignment
will be lost.
