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

Note: If incorrect information is entered into the hand control, the UNDO button acts like a back space button

allowing the user to re-enter the correct data.

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

using the Two-Star Align method:

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

entered, the hand control 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.

•

The hand control will only display stars on one side of

the Meridian. To display alignment stars on the

opposite side of the Meridian, simply press the MENU

button before selecting your first alignment star. By

default, Meridian filtering is enabled with the side of

the Meridian that has the largest number of stars above

the horizon. Meridian filtering is indicated in the upper

right hand corner of the LCD display with an "E" (East)

or "W" (West). If nothing appears in the corner of the

LCD, Meridian filtering is not enabled.

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 hand

control 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 ask you if you wish to add any additional

calibration stars. Calibration stars are used to improve the

pointing accuracy of your telescope by compensating for

subtle optical-mechanical misalignments between the

telescope optics and the mount. Therefore it is usually a

good idea to add at least two additional calibration stasr to

improve the telescope's all-sky pointing accuracy. If you

choose not to add any additional calibration stars you can

always add them later after a successful alignment has been

completed

(see Improving Pointing Accuracy section

elow).

5. Press ENTER to select a calibration star. Select a star the same way you did with the first two

alignments stars and press ENTER. You will notice that all the calibration stars displayed are located

Mount Calibration

After a Two Star Alignment is

successfully completed, the hand

control will ask if you wish to add

calibration stars.

Adding calibration stars is necessary

to calculate and compensate for

"cone" error inherent in all German

equatorial mounts. Cone error is the

inaccuracy that results from the

optical

tube

not

perpendicular

declination axis. The telescope is

able to automatically determine the

cone error value by always using

calibration stars on the opposite

side of the Meridian from the

alignment stars. (see Figure 3-2)

Figure 3-2

The Meridian is an imaginary line in the sky

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.
