AUTOSTAR FEATURES

Nearly all telescope operations are accomplished with just a few pushes of AutoStar’s buttons. Some of the major features of AutoStar are:

N Automatically move the telescope to any of the 30,000 objects stored in the database or

manually enter the astronomical coordinates of any celestial object.

N Take a guided tour of the best celestial objects to view on any given night of the year.

N Access a glossary of astronomical terms.

N Calculate which eyepiece to use for optimum viewing of a celestial object.

The AutoStar Computer Controller provides control of virtually every telescope operation. 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.

NOTE: AutoStar does not require batteries; the telescope’s batteries supply power to AutoStar.

B 2-Line LCD Display: This screen displays AutoStar's menus and information about the tel-

escope.

Top line: Lists the primary menu.

•

• Bottom line: Displays other menus that may be chosen, menu options, telescope status or information about a function that is being performed.

c ENTER Key: Press to go to the next menu level or to choose an option in a menu. The

ENTER key is similar to the RETURN or ENTER key on a computer.

d MODE Key: Press to return to the previous menu or data level. The top menu level is “Select

Item." The MODE key is similar to the ESCAPE key on a computer.

Note: Pressing MODE repeatedly 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 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

• Date

• Site coordinates

• Battery status Press MODE again to return to the previous menu.

e GO TO Key: After the telescope is aligned, press to slew (move) the telescope to the coor-

dinates 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. Also, press during the alignment or GO TO procedures to activate a "spiral search."

f Arrow Keys: The Arrow keys have several functions. Press an Arrow key to slew the tele-

scope in a specific direction (up, down, left and right), at any one of nine different speeds. See

Additionally, use the Arrow keys to to move the cursor across the display: Use the Right or Left Arrow key to move the cursor from one number to the next in the display.

g Number Keys: Press to input digits 0 to 9. To change the speed at which the

telescope moves (known as the “slew” speed) press a NUMBER KEY from 1 through 9. 1 is the slowest speed and 9 is the fastest.

h Scroll Keys: Press to access options within a selected menu. The menu is

displayed on the first line of the screen. Options in the menu are displayed, one at a time, on the second line. Press the Scroll keys to move through the options. Press and hold a

ey to move quickly through the options.

The Scroll keys also control the speed of text scrolling on the AutoStar display. When text is scrolling, press and hold the Up Scroll key for a faster display speed and the Down Scroll key for a slower display speed.

i ? Key: Press to access the "Help" file. "Help" provides on-screen information on how to

accomplish whatever task is currently active.

Press the ? key and then follow the prompts on the display to access details of AutoStar functions in the Help feature. The Help system is essentially an on-screen instruction manual.

If you have a question about an AutoStar operation, press the ? key and follow the directions that scroll on the second line. When satisfied with the Help provided, press MODE to return to the original screen and continue with the chosen procedure.

Initializing AutoStar

This section describes how to initialize AutoStar. Perform this procedure the first time you use AutoStar.

Tighten Locks: Tighten the Altitude lock and tripod base lock knob.

Plug in AutoStar: Make sure the telescope power switch is in the OFF position. Plug

Note: The location settings (country/state/province and city, or zip code) are only asked for the first time you turn on the control panel. If you wish to change this setting later on, use the Site menu.

a. If you chose the zip code option, the leftmost “0” is highlighted. Use the Scroll keys to scroll

through the digits. When you reach the desired number, use the Right Arrow key to move to the next digit position. Repeat this process until all 5 digits of your zip code are entered. Press ENTER.

b. If you chose the location option, the next screen asks for the country or state/province (list-

ed alphabetically) of the observing site. Use the Scroll keys to scroll through the list of countries, states, and provinces. Press

ENTER when the correct location displays. The next screen asks for the city (listed alphabetically) closest to the observing site. Use

the Scroll keys to scroll through the list of cities. Press ENTER when the correct city appears on screen.

8. AutoStar then requests the telescope model number. Use the Scroll keys to cycle through the database of models. Press ENTER when your model number displays.

Easy (Two-Star) Align

The fastest and easiest way to locate objects with Autostar's GO TO capabilities is to use Easy Align.

Autostar automatically picks two stars from its database for the Easy Align procedure. During this procedure, Autostar slews the telescope to a first alignment star. The user is asked to verify that the telescope is pointed at the chosen star and then prompted to center the star in the eyepiece. The process is repeated with a second star to complete the alignment.

NOTE: Before aligning the telescope, first verify that INITIALIZING AUTOSTAR, page 16, has been performed. See MOVING THROUGH AUTOSTAR’S MENUS, page 16, if you wish to learn how to operate Autostar’s keys.

How to Easy Align Your Telescope

If you have just applied power to Autostar, perform steps 1 through 3. If you have already performed the initialization procedure, go to step 4.

Sun Warning - Press the key prompted by Autostar to accept.

Getting Started - Press ENTER to continue.

Daylight Savings - Select “Yes” or “No,” then press ENTER.

Alignment Option Screen - “Setup: Align” displays. Press ENTER.

Select Alignment - “Align: Easy” displays. Press ENTER.

Set Alt/Az Home Position - Autostar then prompts you to set the telescope in the Alt/Az Alignment home position.

To Set the Home Position:

• Loosen the telescope’s Altitude lock

• Level the optical tube: Line up 0° on the Altitude setting circle with the molded triangular pointer next to the circle.

• Tighten the Altitude lock to a firm feel only.
