The AutoStar Computer Controller provides control of virtually every telescope function within
a compact handbox. AutoStar has soft-touch keys designed to have a positive feel. The LCD
(Liquid Crystal Display) is backlit with a red LED (Light Emitting Diode) for easy viewing in the
dark. The backlit display, key arrangement, and sequential database make AutoStar extremely
user friendly.
2-Line LCD Display: Provides an interface between AutoStar and the telescope.
• Top line: Lists the primary category or menu item.
• Bottom line: Contains a menu option or information about an object or subject,
depending on which function is being performed.
ENTER Key : Accesses, in a sequential manner, the next menu or data level in the AutoStar
database. See
MOVING THROUGH AUTOSTAR'S MENUS,
page 18 and
MENU AND MENU
OPTION DESCRIPTIONS,
page 24.
NOTE: If ENTER is pressed for two seconds or more and then released, AutoStar
emits a beep and “ENTER to Sync” is displayed. “ENTER to Sync” is relevant only
after the telescope has been aligned and is pointing at an object. If the “ENTER to
Sync” feature is accessed by mistake, press MODE to return to the previous screen.
See HIGH PRECISION,
page 29, for more details about this feature.
MODE Key : Returns to the previous menu or data level in the AutoStar database until the
top level, “Select Item” is reached. The MODE key is similar to the ESCAPE key on a
computer.
NOTE: Pressing MODE while in the “Select Item” level moves AutoStar to the
topmost screen: “Select Item: Object”.
If MODE is pressed and held for two seconds or more, information about the
telescope’s status displays. When the status displays, press one of the Scroll keys
(
Pg. 10, Fig. 2, 7 ) to display the following information:
• Right Ascension and Declination (astronomical) coordinates
• Altitude (vertical) and Azimuth (horizontal) coordinates
• Local Time and Local Sidereal Time (LST)
• Timer and Alarm Status
• Accessory Port Module (APM) status (see the instructions supplied with the APM)
• Date
• Site coordinates
• Battery status
Press MODE again to return to the previous menu.
GO TO Key : Slews (moves) the telescope to the coordinates of the currently selected
object. While the telescope is slewing, the operation may be aborted at any time by
pressing any key except GO TO. Pressing GO TO again resumes the slew to the object.
Arrow Keys : Slew the telescope in a specific direction (up, down, left, and right), at any
one of nine different speeds. Speed selection is explained in
SLEW SPEEDS,
page 17. The
following functions are also available with the Arrow keys:
• Data entry - Use the Up and Down Arrow keys to scroll through the letters of the
alphabet and numerical digits. The Down Arrow key starts with the letter “A” and
the Up Arrow key starts with the digit “9” The Left and Right Arrow keys are used
to move the blinking cursor left and right across the LCD display.
• Moves the telescope - Use the Up and Down Arrow keys to move the telescope
vertically up and down. The Left Arrow key rotates the telescope horizontally
counterclockwise, while the Right Arrow key rotates it clockwise.
Number Keys : Input digits 0 - 9 and changes the slew speeds (see
SLEW SPEEDS
, page
17). The “0” key also turns on and off the red utility light on the top of the handbox.
NOTE:
Throughout this
manual, you will notice
the term "Alt/Az." Alt/Az
is frequently used to
refer to Altitude
(vertical) and Azimuth
(horizontal). Alt/Az is
just one of many
methods used by
amateur astronomers to
help locate stars in the
night sky.
NOTE:
AutoStar does not
require batteries; the
telescope’s batteries
supply power to
AutoStar.
TIP:
To manually enter
the R.A. and Dec.
coordinates of
an object:
Press and hold MODE
for two seconds or more.
The R.A. and Dec.
coordinates display.
Press GO TO. “Object
Position” and a set of
coordinates displays.
Then enter the R.A. and
Dec. coordinates of any
celestial object using
Number keys. As soon
as the coordinates are
entered, AutoStar slews
the telescope to the
coordinates. Note that
the telescope must be
initialized for this
procedure to
operate properly.
