When without a polar scope or the pole star is not in
sight:
(1) Level the mount and set it at Zero Position. Align
the telescope parallel to the R.A. axis of the
mount. Set correct R.A. and DEC backlash values.
An eyepiece with crosshairs is recommended.
mount. Set correct R.A. and DEC backlash values.
An eyepiece with crosshairs is recommended.
(2) Use HC (MENU => “Align” => “Polar Alignment”)
to display the azimuth and altitude position of
several bright stars near meridian. Select one
that is visible and high in altitude as the
Alignment Star A. Follow the HC instructions to
move the Star A to the center of the eyepiece
with the combination of using Latitude Adj. Knob
and “◄” / “►” buttons. Press ENTER to confirm
the centering. Next, select a bright star that is
close to the horizon as the Alignment Star B.
Center it using Azimuth Adj. Knob and “◄” / “►”
buttons (The “▲” and “▼” buttons are not used
here). Press ENTER to confirm.

(3) The telescope will now slew back to Star A to
repeat above steps. The iteration can be stopped
when it is determined that the alignment error is
at the minimum. Press BACK button to exit the
alignment procedure.

Manual Operation: The mount can now be used to
observe astronomical objects with the HC. Use arrow
keys (►, ◄, ▼, and ▲) to point the telescope to the
desired object. Use the number keys to change the
slewing speed. Press STOP/0 button to start tracking.

Latitude and longitude coordinates can be obtained
from GPS‐equipped devices (navigator, phone), or
from internet. “W/E” = western/eastern hemisphere;

One Star Alignment: Make sure the mount is at ZERO
position by press MENU => “To Zero Position”.
Perform One Star Align to correct the Zero Position
discrepancy. To further improve the GOTO accuracy,

Go to an Object: The mount is now ready for GOTO
and tracking targets. Press MENU, select and ENTER
“Select and Slew”. Select a category (for example,
“Planets, Sun, Moon”), then an object (for example,
“Moon”). Press ENTER and the telescope will slew to

Sync to Target: If the object is not in the center of
the eyepiece, use this function to center and
synchronize the object to improve local GOTO
accuracy. Press MENU and select and ENTER “Sync

centered in eyepiece. Press ENTER again to complete
this function.

[TIP: “Sync to Target” can only function after a
“Select and Slew” operation. This is most useful
when looking for faint objects near a bright star.

Reminder on Tension Adjusters
The Tension Adjusters are used as the last step to
lock, and the first step to release the gears. Never
fully tighten them during operations. The optimum
position is one just deep enough to rid any plays.
Hesitation in turning the Gear Switch by 90° means
the Tension Adjuster has not been loosened enough.
