DEFINITION:

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 .

Time and Date infor-

mation is set at the

factory (and do not

need to be entered by

the observer). This

information is held by

a long-life battery.

See

APPENDIX E

page 39, for more

information.

During the procedure,

you will enter the

observation location.

Autostar uses loca-

tion, plus time and

date information to

precisely calculate the

location of celestial

objects (such as stars

and planets) and to

move your telescope

correctly for various

Autostar operations.

setting circle.

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.

Initializing Autostar

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

Autostar or after performing a RESET (see

RESET, page 28).

1. Tighten Locks: Tighten the Altitude lock (10, Fig. 1) and tripod base lock knob (26, Fig. 1).

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

Autostar into the HBX port of the Control Panel.

3. Turn on Autostar: Flip the telescope power switch to the ON position.

4. Sun Warning: A message displays that warns you not to look at the Sun. At the end of this

message, press the key prompted by Autostar to signify that the message has been read

and understood.

5. Bypass Getting Started: The Getting Started menu displays a scrolling message. Press

ENTER (2, Fig. 2) to bypass the Help tutorial.

6. Daylight Savings Time: The next screen requests the status of Daylight Savings Time.

Press one of the Scroll keys to toggle between the YES/NO settings. When the desired set-

ting displays, press ENTER.

NOTE:

When multiple choices are available within a menu option, the current option

is usually displayed first and highlighted by a right pointing Arrow (>).

7. Set Your Location or Zip Code: The Location screen displays. This screen asks you if you

wish to choose either the zip code of your observing location or the location (

i.e.,

entering the

city and state or country of your observing location). Press Up to select the zip code option

or down to enter the city and state.

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 set-

ting later on, use the Site menu. See

SITE

, page 28, for more information.

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.

9. System initialization is complete. The Easy Alignment feature begins automatically after

the control panel is initialized.

Observe a Star using the Automatic Tracking Feature

In this example, the Autostar Arrow keys are used to find a star, and then Autostar's tracking

capability automatically keeps the star centered in your telescope's eyepiece.

1. Set in Home Position: Level the optical tube and point it North. Make sure that the Altitude Lock

(9, Fig. 1) and tripod base lock knob (26, Fig. 1) are secured as described previously.

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

Autostar into the HBX port of the Control Panel.

3. Turn on Autostar: Flip the telescope power switch to the ON position.

4. Sun Warning: A message displays that warns not to look at the Sun. At the end of this mes-

sage, press the key prompted by Autostar to signify that the message has been read and

understood.

5. Select Daylight Savings: Set Daylight Savings, if prompted.

6. Select Setup: Align Option: Press MODE (2, Fig. 2). "Setup: Align" displays.
