then “sync” on this star and slew to the position that the
star should be if it were accurately polar aligned.
Note: For the most accurate alignment, it is best to use a
reticle eyepiece or a high power eyepiece to precisely center
the star in the field of view.
3. Use the mount’s latitude and azimuth adjustments to
place the star in the center of the eyepiece. Do not use
the direction buttons on the hand control to position the
star. Once the star is centered in the eyepiece, press
ENTER; the polar axis should now be pointed towards
the North Celestial Pole.
Updating your Star Alignment
After polar alignment, it is a good idea to check the pointing
accuracy of the telescope to see how much it may have been
affected by moving the mount. Since the polar alignment
process requires you to “sync” the telescope on a bright
star before you begin, it will be necessary to undo the sync
before re-aligning. To undo the sync:

press Enter. The message Complete will display on the

To re-align your telescope:
1. Slew the telescope to one of the original alignment stars
or another bright star if the original alignment stars are
no longer in a convenient location. Press the Align button

5. Repeat the process on a second alignment star.
For additional all-sky pointing accuracy, it is a good idea to
align on at least one additional calibration star located on
the opposite side of the Meridian. To add calibration stars:
1. Slew the telescope to a bright star on the opposite side
of the Meridian from your two alignment stars.

Pointing at Polaris
This method of Polar aligning utilizes Polaris as a guidepost
to the celestial pole. Since Polaris is less than a degree from
the celestial pole, you can simply point the polar axis of your
telescope at Polaris. Although this is by no means perfect
alignment, it does get you within one degree and is suitable
for visual observing and short exposure piggyback photography.
This must be done in the dark when Polaris is visible and can
be done using the hole in the polar axis or with the help of
the optional polar axis finderscope.
1. Set up the telescope so the polar axis is pointing towards
north.
2. Remove the polar finderscope cover and the polar axis
cover from both sides of the mount. The polar finderscope
cover unthreads from the rear of the mount, and the polar
axis cover presses into the front of the mount

Finding the North Celestial Pole
In each hemisphere, there is a point in the sky around which
all the other stars appear to rotate. These points are called
the celestial poles and are named for the hemisphere in
which they reside. For example, in the northern hemisphere
all stars move around the north celestial pole. When the
telescope’s polar axis is pointed at the celestial pole, it is
parallel to the Earth’s rotational axis.
