on should be able to see the star cleared as well. If one cannot have both focused at the same
time, please see Appendix for Polar Scope adjustment.
(5) Slightly release R.A. Clutch Screw. Press the LFTT or RIGHT button on the hand controller to
rotate the polar scope to align the 12 o'clock position of the dial on the top, as shown in Figure 17.
(6) Make sure that the time and site information of the hand controller is correct. Press MENU =>
"Alignment"=> "Pole Star Position" to display the current Polaris position. For example, on June
22, 2014, 20:19:42 in Boston, US (alt N42º30'32" and long W71º08'50"), UTC -300 minutes,
DST:Y, the Polaris Position is 0h45.8m and 40.4m,.as shown in Figure 18a.
(7) Look through the polar scope to find the Polaris. Using Azimuth Adjustment Knob and Latitude
Adjustment Screw to adjust the mount in altitude and azimuth directions and put the Polaris in the
same position on the Polar Scope Dial as indicated on the HC LCD. In this case, the Polaris will be
located at a radius of 40.4' and an angle of 0 hour 45.8 minute, as shown in Figure 18b.

NOTE: If you are located in southern hemisphere, Sigma Octantis will be chosen for Polar
Alignment. For example, on May 20, 2010, 20:00:00 in Sydney, Australia (Lat S33º51'36" and Long
E151º12'40"), 600 min ahead of UT, the Sigma Octantis Position is 1hr21.8m and 64.4m.
BrightStar Polar Alignment/Polar Iterate Align
BrightStar Polar Alignment allows you to polar align the mount even if you cannot view the
Celestial Pole.
(1) Level the SmartEQ pro+ mount and set it at Zero Position. Make sure the telescope is parallel to
the pole axis (R.A. axis) of the mount. If a finder scope is used, adjust it to be parallel to the
telescope optical axis. Turn the mount power on.
(2) Pressing MENU=>Alignment=>Polar Iterate Align. The HC will display the azimuth and altitude
position of several bright stars near meridian. Select one that is visible with high altitude as
Alignment Star A. Follow the HC instruction to move the Star A to the center of the eyepiece with
the combination of Latitude Adjustment Knob and "◄" or "►" button. Press ENTER to confirm.
Next, select a bright star that is close to the horizon as the Alignment Star B. Center it using the
Azimuth Adjustment Knob and "◄" or "►" button (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
alignment procedure.
NOTE: The movement of the alignment star in your eyepiece may not be perpendicular but crossed,
depends on its location in the sky.
