Initialization is a

procedure that

ensures that AutoStar

operates correctly.

When you first use

AutoStar, it doesn't yet

know where the

observation location

site is.

During the procedure,

you will enter

the observation l

ocation or zip code.

AutoStar uses this

information, along with

the time and date

information

provided by the LNT

module, to precisely

calculate the location

of celestial objects

(such as stars and

planets) and to move

your telescope

correctly for various

operations.

Important Tip:

It is recommended

that y

ou tr

ain you

telescope’s drive the

first time y

ou align

your telescope.

Training the drive

impro

ves your

telescope’s pointing

precision.

about pointing y

Astronomical Observing

Used as an astronomical instr

ument, your telescope has many optical and electromechanical

capabilities. It is in astronomical applications where the high level of optical performance is

readily visible. The range of observable astronomical objects is, with minor qualification, limited

only b

y the observer’s motivation.

To Track an Object Automatically

As the Earth rotates beneath the night sky, the stars appear to move from East to West. The

speed at which the stars move is called the sidereal rate.You can setup your telescope to move

at the sidereal rate so that it automatically tracks the stars and other objects in the night sky. If

the telescope is not tracking an astronomical object, the object will drift out of the eyepiece field

of view. The tracking function automatically keeps an object more or less centered in the

telescope’s eyepiece.

To automatically track objects, you must initialize AutoStar, and then select "Targets:

Astronomical" from the AutoStar Setup menu. You must also learn how the AutoStar keypad

operates in order to move through the AutoStar menus.

Moving Through AutoStar’s Menus

The AutoStar database is organized in levels for quick and easy navigation.

• Press ENTER to go deeper into AutoStar's menu levels.

• Press MODE to move back toward the top menu level.

• Press the Scroll keys to move up and down through the options available for each

level.

• Press the Arrow keys to enter characters and digits.

The Arrow keys are also used to move the telescope.

Initializing AutoStar for the First Time

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

AutoStar or after performing a Reset (see

“RESET,” page 29).

AutoStar will ask you to choose your observing location (or zip code) and your telescope’s

model number from the list it displays. You will be prompted to enter this information

only the

first time you use AutoStar.

If you wish to change your location information (or if AutoStar

does not ask you for this information information the first time that you use it), go to the Site

option of the Setup Menu to select your location. See page 30 for more information.

1. Tighten the vertical and horizontal locks (

6 and 9, Fig. 1) if necessary.

2. Make sure that AutoStar is connected to the HBX port (

C, Fig. 2) and SmartFinder is

connected to an AUX port (

D, Fig. 2) of the telescope’s computer control panel.

3. Flip the telescope power switch (

A, Fig. 2) to the ON position.

The A

utoStar screen displays a copyright message, followed by a short beep. Then

AutoStar takes a few moments to start up the system.

4. A message displays that warns not to look at the Sun. At the end of this message, press

the k

ey prompted by AutoStar to signify that the message has been read and understood.

the Help tutorial and continue with initialization.

utoStar then displa

choose how you wish to enter the location of your observing site: You can enter your zip

code or choose the site from a list of countries, states and cities.

Press the number key “1” if you wish to enter by zip code. Then enter the five

digits of the zip code of your observing site and press ENTER.

Press the number key “2” if you wish to select your observing site from a list of country,

states and cities

First, use a Scroll k

(listed alphabetically). Press ENTER when the correct location displays. Next, use a Scroll

key to cycle through the list of cities (also listed alphabetically). Press ENTER when the

closest city displa

7. 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.

System initialization is complete and the screen reads "Align:

utomatic."
