HOW TO USE

III. Practice (Taking Photography)

Align to the Celestial Pole

Procedure to start up photographing:

Set up the POLARIE U so that it turns to  
follow the diurnal motion of stars. To do 
this, the rotational axis of the POLARIE 
U must be set to be parallel to the axis 
of the diurnal motion of stars.  
The process is called polar alignment.

The process of the polar alignment 
differs between the northern hemisphere 
and the southern hemisphere. The polar 
alignment in the northern hemisphere is 
explained as an example here.
 

In case of the polar alignment in 
the southern hemisphere, use a 
conspicuous pattern of 3 stars in the 
constellation Octans. It is recommended 
to use an optional Polar alignment 
scope PF�LII.
