Looking at or near the 

Sun

will cause 

irreversable

damage to your eye. Do not point this telescope at or near the

Sun. Do not look through the telescope as it is moving.

One-Star Alt/Az Alignment 

One-Star Alignment requires some knowledge of the night sky. AutoStar provides a
library of bright stars. One-Star Alignment is identical to Two-Star Alt/Az: Alignment (see

TWO-STAR ALT/AZ ALIGNMENT

, page 38), except only one star from the database is

chosen by the observer for alignment.

This menu

Parameters: Smallest (mins)" displays. Enter the value for the smallest size of an
object that AutoStar will search for in the database. Continue with "Brightest,"
Faintest," and "Minimum Elevation," using the procedure described in steps 3 and
4.

6.

After "Minimum Elevation," "Object Type" displays. Press ENTER." "+Black Hole" 
displays.If you do 

not wish wish to have "Black Holes" in your search, press ENTER

and the "+" changes to a "–." Press the Scroll Down to scroll to the next item.

you wish to change the "+" to a "–" or vice-versa.

7.

and the Scroll Down key once. "Browse: Start Search" displays. Press ENTER.
"Start Search: Next" displays. Press ENTER. AutoStar searches the database and
displays the first object that matches the search parameters you have entered. Use
the scroll keys to display information about the object. Press MODE and "Start
Search: Next" displays again. Press ENTER and the next item matching the param-
eters displays. Repeat this procedure to display all the objects.
