means northern/southern hemisphere; "d" means
degree; "m" means minute; and "s" means second.
Move the cursor to the bottom of the screen to select
Northern or Southern Hemisphere.
10. Polar Alignment: Remove both Polar Scope and
polar axis covers. Look through the polar scope to
locate Polaris (or Sigma Octantis at southern
hemisphere). Slightly loosen the Azimuth Locking
Screws and Latitude Locking Screws. Use the two
Azimuth Adjustment Knobs to center the pole star in
the azimuth direction. Use the Latitude Adjustment
Knob for the latitude adjustment. Tighten the screws
after adjusting.
Quick Polar Alignment:
Fast and accurate polar alignment can be performed
with iOptron's AccuAlign
a. Thread the dark field illuminating LED into the
thread-in hole on a polar scope. Plug the LED
cable into the LED and the Reticle socket
located on the main control board.
b. Turn the mount power on. Use Hand Controller
("Settings" => "Set Eyepiece Light") to set the
illumination intensity.
c. Use the " or "
▲"
unblock the Polar Scope view (there is a hole on
the DEC axis).
d. Use the "◄" or "►" button to turn the RA axis to
rotate the Polar Scope dial to a clock position
where 12 is at the top, as shown in Figure 13.

e. Use Hand Controller (MENU => "Alignment" =>
"Pole Star Position") to display the Polaris
Position on the LCD screen, as indicated in
Figure 14 (a). For example, June 22, 2014,
20:19:42 in Boston, US (alt N42º30'32" and long
W71º08'50"), UTC-300 minutes, the Polaris
Position is 0h45.8m and 40.4m.

f. Use the Azimuth and Latitude Adj. Knobs to
adjust the mount in both directions and put the
Polaris in the location on the Polar Scope Dial
(same as indicated on the HC LCD), as shown
in Figure 14 (b).
Polar Iterate Alignment (BrightStar Alignment)
When 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. If a finder scope is used, adjust it to be
parallel to the telescope optical axis. An eyepiece
with crosshairs is recommended.
(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 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 the 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 the above steps. The iterations can be
stopped when it is determined that the alignment
error has been minimized. Press the BACK
button to exit the alignment procedure at anytime
that the result is acceptable.
11. Setting Zero Position: The Zero Position is the
position where the counterweight shaft points to
ground, telescope is at the highest position with its
axis parallel to the polar axis and the telescope is
pointing to the Celestial Pole. It needs be set. Use
Hand Controller (MENU => "Zero Position" => "Set
Zero Position") to bring up menu. Loosen the DEC
and R.A. Clutches to manually adjust the mount to
