In order for a motor drive to track accurately, the telescope's axis of rotation must be parallel to the Earth's axis of
rotation, a process known as polar alignment. Polar alignment is achieved NOT by moving the telescope in R.A. or
Dec., but by adjusting the mount vertically, which is called altitude. This section simply covers the correct
movement of the telescope during the polar alignment process. The actual process of polar alignment, that is
making the telescope's axis of rotation parallel to the Earth's, is described later in this manual in the section on
"Polar Alignment."

To increase the latitude of the polar axis, loosen the latitude locking bolt slightly -- Figure 2-27.
•
To increase or decrease the latitude of the polar axis, tighten or loosen the latitude adjustment screw. Then,
tighten the latitude locking bolt securely. Be careful when turning the screws to avoid hitting your fingers or
having them scrapped on other screws, etc.
The latitude adjustment on the PowerSeeker mount has a range from approximately 20° to 60°.
It is best to always make final adjustments in altitude by moving the mount against gravity (i.e. using the rear
latitude adjustment screw to raise the mount). To do this you should loosen the latitude adjustment screw and then
manually push the front of the mount down as far as it will go. Then tighten the adjustment screw to raise the mount
to the desired latitude.
