(10) to scroll through the choices. Refer to Time Zone map in Appendix for more

information.

• Date - Enter the month, day and year of your observing session.

• Finally, you must enter the longitude and latitude of the location of your observing site.

Use the table in Appendix C to locate the closest longitude and latitude for your current

observing location and enter those numbers when asked in the hand control, pressing ENTER

after each entry. Remember to select "West" for longitudes in North America and "North" for

latitudes in the North Hemisphere. For international cities, the correct hemisphere is indicated

in the Appendix listings.

4. Select one of the four alignment methods as described below.

Auto Two-Star Align

Auto Two-Star Align allows the user to select two stars on which to align the telescope. To Auto Align your

telescope:

1. Select Auto Two-Star from the alignment choices given. Based on the date and time information

entered, the CGE will automatically select and display a bright star that is above the horizon.

• Press ENTER to select this star as your first alignment star.

• If for some reason the chosen star is not visible (perhaps behind a tree or building) press UNDO

to have the hand control automatically select the next brightest star.

• Or you can use the Up/Down keys to browse the entire Named Star list and select any one of

over two hundred alignment stars.

2. Once the telescope is finished slewing to your first

alignment star, the display will ask you to use the arrow

buttons to align the selected star with the cross hairs in the

center of the finderscope. When centered in the finder, press

ENTER.

3. The display will then instruct you to center the star in the

field of view of the eyepiece. When the star is centered,

press ALIGN to accept this star as your first alignment star.

4. After the first alignment star has been entered the CGE will

automatically select a second alignment star and have you

repeat this procedure for that star. When the telescope has

been aligned on both stars the display will read

Alignment Successful, and you are now ready to

find your first object.

For the best possible pointing accuracy, always center the alignment

stars using the up arrow button and the right arrow button.

Approaching the star from this direction when looking through the

eyepiece will eliminate much of the backlash between the gears and

assure the most accurate alignment possible.

Auto One-Star Align

Auto One-Star Alignment works much the same way as Auto Two-Star Align but uses only a single star in the

sky for alignment. This method of alignment is not as accurate as the two-star alignment and is recommended

only for telescopes that are permanently and accurately polar aligned.

Tip

Figure 3-2

The Meridian is an imaginary line in the sk

that starts at the North celestial pole and

ends at the South celestial pole and passes

through the zenith. If you are facing South,

the meridian starts from your Southern

horizon and passes directly overhead to the

North celestial pole.
