Time changes the time entered into Autostar. Setting the
correct time is critical for Autostar to properly calculate loca-
tions and events. 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:
Telescope Model: Selects the model of telescope con-
nected to Autostar.
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.
Train Drive: Trains the Altitude and Azimuth motors to
locate objects with more precision.
If you are experiencing any problems with pointing
accuracy, or performed a Reset, follow the procedure
described in "TRAINING THE DRIVE," page 13, to
insure accurate pointing and tracking.
Tracking Rate: Changes the speed at which the tele-
scope tracks targets in the sky.
a. Sidereal: The default setting for Autostar; sidereal
rate is the standard rate at which stars move from
East to West across the sky due to the rotation of
the Earth.
b. Lunar: Choose this option to properly track the
Moon over long observing sessions.
c. Custom: Allows entry of user-defined tracking
rates.
Reverse L/R: Reverses the functions of the Left and
Right Arrow keys (i.e., the Right key moves the tele-
scope to the left).
Reverse UP/DOWN: Reverses the functions of the Up
and Down Arrow keys (i.e., the Up key moves the tele-
scope down).
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 eye-
piece, 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.
