Aligning the Telescope

Polar Home Position

Point the telescope at Polaris with the right ascension set to 00h:00m.
hint: use the setting ring on the telescopes mount.

This is called the "polar home position" and at this point the angle between the telescope tube and the horizontal should be the same as your observing latitude.

A good way to make sure you are in the polar home position is to unlock the telescope mount so that it is free to move in right ascension, and slew the telescope 360° while watching Polaris through the spotting scope. If you have pointed to Polaris properly it should make a wide circle about the spotting scope's center and not go outside the field of view.
Note: the spotting scope must be aligned with the optical tube for this method to work.

Starting The Alignment

Once in the polar home position press enter, choose a relatively bright—and visible—star from the list, and press enter again. The telescope will then slew to the star you chose.

The telescope will beep when it is done slewing, and allow the user to center the star in the eye piece with the directional arrows on the autostar remote. Once the user has centered the star they should press enter once more, and the alignment is either finished, or a new star will be chosen and the process repeated (depending on whether 1 or 2 star alignment was chosen).
Note: when performing a 2 star alignment, it is imperative that the chosen stars be at a great angular distance from each other.
