BrightStar Polar Alignment
If you mount does not have a iPolar installed, or the pole star is not in sight, you may use two bright
stars with Polar Iterate Align to do the polar alignment.
(1) Level the mount and set it to the Zero Position. Align the telescope to the R.A. axis of the
mount. If a finder scope is used, adjust it to be parallel to the telescope optical axis.
(2) Use the HC (MENU => “Alignment” => “Polar Iterate Align”) to display the azimuth and
altitude position of several bright stars near the meridian. Select one that is visible at a high
altitude as Alignment Star A. Follow the HC instruction to move Alignment Star A to the
center of the eyepiece using a combination of the Latitude Adjustment Knob and the “◄” or
“►” buttons. Press ENTER to confirm when the star is centered. Next, select a bright star
that is close to the horizon as Alignment Star B. Center it using the Azimuth Adjustment
Knob and the “◄” or “►” button (the “▲” and “▼” buttons are not used here). Press ENTER
to confirm the settings.
(3) The telescope will now slew back to Alignment Star A. Repeat the steps above. The iteration
can be stopped when it is determined that the alignment error has been minimized. Press
the BACK button to exit the alignment procedure.
NOTE: It is highly recommended to use an eyepiece with an illuminated crosshair for accurate
centering.
NOTE: The movement of the alignment star in your eyepiece may not be perpendicular depending on
its location in the sky.
STEP 13. Returning the Mount to Zero Position
After polar alignment and balancing OTA, return the mount to the Zero Position. Please check the zero
position after set up the mount or firmware update.
