latitude from your smart phone or internet using your current address. If the north pointing and the
latitude set are correct, you should be able to find the Polaris through the Polar Sight Hole. Center the
Polaris inside the Polar Sight Hole as good as possible for the polar alignment. Retighten all the
screws and locks.
For those located in the southern hemisphere, use Sigma Octantis in Octans as the pole star.

STEP 5. Easy Polar Alignment
TM
This STEP will discuss how to use iOptron's AccuAligning dark field illuminated polar scope (Figure
10) for easy and accurate polar alignment. You may skip this part and directly go to STEP 6, if your
TM
model does not equipped with a polar scope (Model #3301). In order for the SkyTracker mount
tracking properly, it has to be accurately polar aligned. This is achieved by making the polar axis of
the mount parallel to that of the Earth's axis of rotation.

Before installing the polar scope onto the mount, face the polar scope to a bright source, such as the
sky (but not the SUN) or a lamp from distant. Adjust the eyepiece to focus the reticle pattern. Then
face the polar scope to a distant object and look through the eyepiece. If you can not see the distant
object clearly, the polar scope is not focused for your eyesight. Release a few turns of the Lock ring.
Turn the Objective lens until the image is focused. Retighten the Lock ring.
