1. Slightly loosen the knob that keeps the mount fixed to the tripod base to allow its 

Azimuth rotation, while still keeping it safely on the tripod. 

2. Slightly loosen the black knurled side knobs to allow the Latitude (altitude) movement. 
3. Put the polar scope’s star diagonal in a comfortable position and tighten all 

knobs

 in this 

position. 

4. Once you are confident that the polar scope is correctly oriented, use small movements of

the Azimuth and Altitude adjustment knobs

 

to place Polaris exactly in the center of the 

classical reticle’s corresponding small circle in or in the defined hour position for the 
newer type reticle. 

5. When finished, firmly re-tighten the Altitude and Azimuth knobs as well as those fixing 

the mount to the tripod. The mount is now aligned to the celestial North Pole. 

In case of use of the new reticle (on the right figure) the only difference is that, being missing
the small circle correspondent to the Polaris, the star must be brought to the position in the
graduated circle defined by the specific application.

5.3.2  Polar Alignment with a Losmandy polar scope

he Losmandy polar scope, which is provided
as an option, allows a more precise
alignment because it is based upon the 
positioning of three stars (Polaris, 

UMi,

OV Cep ) in concurrence with the
corresponding locations in the scope reticle
which looks like the illustration on the right.
If you are located in the northern
hemisphere, ignore the dotted lines because
they pertain only to the Southern
Hemisphere.
The alignment operations with this kind of
polar scope are the following:
1. Slightly loosen the knob that keeps the

mount attached to the tripod base to allow its Azimuth rotation, while still keeping it safely 
on the tripod. 

2. Slightly loosen the black knurled side knobs to allow the Latitude (altitude) movement. 
3. Put the polar scope’s star diagonal in a comfortable position and tighten its latches in this 

position.

4. Rotate the polar scope around its axis until the gap related to Polaris is oriented at the hour 

angle previously determined. To help to make this operation more precise, the dial attached
