Looking at or near the Sun will cause irreversible damage to your eye. Do not point this telescope at or near the
Sun. Do not look through the telescope as it is moving.
The A
utostar II system provides control of virtually every telescope function. The
Autostar II handbox has soft-touch keys designed to have a positive feel. The LCD
(Liquid Crystal Display) is backlit with red LEDs (Light Emitting Diodes) for easy view-
ing in the dark. The backlit display, key arrangement, and sequential menu structure
mak
e Autostar II extremely user friendly.
B 2-Line LCD Display: This screen displays Autostar II's menus and information
about the telescope.

Autostar II to the topmost screen: “Select Item: Object.”
Note: If MODE is pressed and held for two seconds or more, information
about the telescope's status displays.When the status displays, press the
Scroll keys (

resumes the slew to the object. Also, press during the alignment or GO TO pro-
cedures to activate a "spiral search."
f Arrow Keys: The Arrow keys have several functions. Press an Arrow key to slew
the telescope in a specific direction (up, down, left, and right), at any one of nine
different speeds. See
SLEW SPEEDS, page 26. Use the Up and Down Arrow keys
to move the telescope vertically up and down.The Left Arrow key rotates the tele-
scope horizontally counterclockwise, while the Right Arrow key rotates it clockwise
(unless reversed for Southern Hemisphere use).
Also, use the Arrow keys to scroll through numbers 0 through 9 and the alphabet.
The Down Arrow key begins with the letter "A;" the Up Arrow key begins with digit
"9."
Additionally, use the Arrow keys to move the cursor across the display: Use the
Right or Left Arrow key (
