iOptron iEQ30 Pro Instruction Manual page 19

As indicated in Figure 18, the Polar Scope reticle has been divided into 12 hours along the
angular direction with 10 minute tics. There are 6 concentric circles in 2 groups of 3 marked from 36' to
44' and 60' to 70', respectively. The 36' to 44' concentric circles are used for polar alignment in
Northern Hemisphere using Polaris, while the 60' to 70' circles are used for polar alignment in Southern
Hemisphere using Sigma Octantis.
Quick Polar Alignment
(1) Level the iEQ30 Pro mount. Make sure the telescope optical axis is parallel to the polar axis (R.A.
axis) of the mount. If using a finder scope, adjust it to be parallel to the telescope optical axis.
Remove both the Polar Axis Cover and Polar Scope Cover.
(2) Thread the polar LED into the threaded hole located on the Polar Scope. Connect one end of the
polar scope power cable to the illumination LED and the other end to the Reticle socket located on
main control board. Turn the mount power on. Use the Hand Controller ("Settings" => "Set
Eyepiece Light") to set the illumination intensity.
(3) Use the ▲ or ▼ key to turn the DEC axle to unblock the Polar Scope view.
(4) Adjust polar scope eyepiece shown in Figure 20 to bring the polar scope dial in focus.
