for the observer to choose from. Use the Scroll keys to scroll to a star on the list

that you wish to align upon. Select a star that you can easily locate in the night

sky. Press ENTER.

One-Star Alt/Az Alignment

One-Star Alignment requires some knowledge of the night sky. Autostar II provides a

library of bright stars. One-Star Alignment is identical to Two-Star Alt/Az: Alignment

(see

TWO-STAR ALT/AZ ALIGNMENT, page 42), except only one star from the data-

base is chosen by the observer for alignment.

To Download the Latest Version of Autostar II Software

Included with your telescope is a CD ROM and a USB cable. You need to install the

USB drivers, that are included on the CD ROM, BEFORE plugging in the cable:

1 Select RCX Users (the fourth selection on the list) from the CD Rom.

2 Follow on screen instructions (click “Next” and “Finish” buttons when asked to

do so).

3 Plug in the USB cable. Plug one end into one of the RCX400 USB ports on a

computer control panel/ Plug the other end into a USB port of your PC.

Next, you will install the Autostar Suite software from the CD ROM. This software

provides a menu that allows you to download the latest version of Autostar II

Note:

Autostar II locates align-

ment stars based on the

date, time, and location

entered. The alignment

stars may change from

night to night. All that is

required is for the observer

to center the selected stars

in the eyepiece when

prompted.

Tip:

Try a Spiral Search

The GO TO key also allows

you to perform a "spiral

search." A spiral search is

useful when the telescope

slews to an object, but that

object is not visible in the

eyepiece after the tele-

scope finishes its search.

(This sometimes occurs

during an alignment proce-

dure.) Press GO TO when

the slew is finished and the

telescope starts slewing in

a spiral pattern at a very

slow speed around the

search area. Look through

the eyepiece and when the

object does become visible,

press MODE to stop the

spir

al search.

Then use the

Arrow keys to center the

object.
