Step1

Go to the Setup menu and choose Align: Two Star. Choose "Enter."

Step2

Put the telescope in Home position by loosening the Dec. lock and setting the optical tube to zero degrees on the Dec.'s setting circle. Retighten the Dec. lock. Be sure the tripod base is level. Now move the telescope's base so the computer control panel is facing south. Undo the R.A. lock and point the telescope's optical tube north by moving it horizontally. Retighten the R.A. lock and select "Enter."

Step3

Select "Enter" a second time. Now you will see Select Star on the display. Use the Scroll keys to find the first star you would like to use for your alignment. Press "Enter."

Step4

After the telescope slews to the star, use the arrow keys to center the star in the eyepiece. Select "Enter."

Step5

Choose the second alignment star using the same procedure. Now you are ready to use the telescope's "Go To" capabilities.
