Check the Hand Controller Battery
There is a real time clock in the hand controller. If the hand controller has lost its date and time,
please check the battery.
STEP 8. Perform polar alignment
BrightStar Polar Alignment
If your mount does not have an iPolar installed, or the pole star is not in sight, you may use two
bright stars with
Polar Iterate Align
to perform a coarse 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
(t
he “▲” 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.
iPolar Polar Alignment
HAE may use an external iPolar
TM
electronic polar scope. Just place the iPolar over the bubble level
on top of the mount and secure the thumb screws.
