outside area with few obstructions and an open sky . The telescope

should be prepared for observing with lens covers removed, a low

power eyepiece installed and the viewfinder aligned.

Use MODE to return to the main menu (“Select Item:”). Chose the

“Setup” menu and press ENTER. Press ENTER again to select the

“Align” menu. Press ENTER a third time to begin the “Easy” Align

procedure and follow the instructions given by Autostar. The first

action is to put the telescope in the “Home” position. Home position

for all telescope models is with the telescope tube level (at 0°) and

pointed North. ETX telescopes must also have the base in a special

position to avoid internal hardstops. Begin by releasing the ETX

horizontal lock lever. Turn the telescope counterclockwise until it

stops. Next turn the telescope clockwise until the fork arm is directly

over the computer control panel and lock the horizontal axis.

With the telescope in the home position (level and pointed North),

press ENTER. Autostar now selects a bright star and moves the

telescope to point near it. Using the ARROW keys, center the star in

the viewfinder and then in the eyepiece. The alignment star should

be easily recognized and is the brightest object in the sky where the

telescope is aimed. When the star is centered, press ENTER.

Autostar then selects a second star and points the telescope toward

it. Repeat the same procedure as used on the first star. If the

alignment operation was done accurately, Autostar displays, “Align

Successful.” The telescope begins tracking (motors can be heard

making a low hum) and the screen returns to the main menu.

*Hint* If a selected star is not visible or is behind an obstacle, press

a SCROLL key and Autostar makes another selection. The SCROLL

key can be pressed as often as needed to locate a visible star.

*Problem* If Autostar detects inconsistent data the screen reads:

“Alignment Failed.” Repeat the alignment procedure until successful.

Finding Objects in the Sky

With Autostar aligned, it is possible to find any visible object in the

“Object” menu. Another option, is to take a Guided Tour.

Guided Tour picks the best objects available for viewing. To start a

guided tour, select the “Guided Tour” function from the main menu.

Use the SCROLL keys to view the list of tour objects and press

ENTER to select any object of interest. When selected, the object

name appears on the top line and information about the object is on

the bottom line. Object information includes: astronomical

coordinates, size, brightness, and more. All information can be seen

using the SCROLL keys. Some objects have a moving message with

a description of the object. If a moving message appears, use

MODE to exit the message when completed.

To direct Autostar to point the telescope at a selected object, press

GO TO. The telescope moves at high speed toward the object. The

telescope slows as it approaches the object and eventually stops

and sounds a beep. The object should be visible in the eyepiece of

the telescope. To see more objects in the Guided Tour, press MODE.

Display a new object with the SCROLL keys and press ENTER to

select it. Use this method to view any of the Guided Tour objects.

*Problem* If objects are not in the eyepiece after GO TO is pressed,

check the viewfinder to see if it is near the center. Under high

magnification, some objects may be slightly out of the field of view

and need some minor manual correction using the ARROW keys.

If the object was not close to center, there are several possibilities.

First, the telescope must sit on a stable surface or tripod. Second,

use only the ARROW keys or GO TO key to move the telescope or

alignment is lost. Third, be sure the date, time, and site are

accurately entered. Fourth, make sure the telescope axis locks are

firmly engaged to prevent slippage of the internal clutch. Fifth,

telescope training must be accurate. Repeat very carefully all of the

steps to train the telescope. Last, the alignment procedure must be

done accurately. Make sure each step is done carefully and that

alignment stars are centered.

Synchronize Function: To improve the ability of Autostar to find

objects, a “sync” function is included to make minor alignment

corrections. If an object is not centered in the eyepiece, press and
