Turn the Polar Scope Lock Screw until it does not intrude into the Polar Scope Mounting Hole. The flat
surface inside the mounting hole is for polar scope alignment and the LED acts as both the power
indicator and the illuminating light for the polar scope reticle, as shown in Figure 11. Gently insert the
polar scope into the Polar Scope Mounting Hole with the flat platoon on the polar scope face down.
Push the polar scope all the way in so the flat surfaces inside the hole will align to the flat platoon on
the polar scope and the LED will sit right to the little opening on the flat platoon. Finger tighten (not too
tight) the Polar Scope Lock Screw (Figure 12).

70', respectively. The 36' to 44' concentric circles are used
for polar alignment in the northern hemisphere using Polaris.
While the 60' to 70' circles are used for polar alignment in
the southern hemisphere using Sigma Octantis.
To maximize the benefits of the iOptron polar scope for
polar alignment, you need to know where the Polaris is in
the northern hemisphere. You may find this information via
an iPhone/iPad app (iOptron Polar Scope in Apple iTune
store). Shown in Figure 14 is a screen shot of an iPhone
