While looking into the eyepiece of the polar
alignment scope, adjust the direction of the
mount by turning the altitude adjustment
bolt and azimuth adjustment knobs so that
Sigma Octantis comes as close as possible
to the designated position on the reticle.
Set Sigma Octantis to the gap between the two segments of the lines
marked 2014 and 2040 adjacent to a mark „σ Oct" as shown in the
figure.

As Sigma Octantis shifts to the designated position on the reticle, both
Tau Octantis and Chi Octantis come close to their own designated
position scales respectively. While looking into the eyepiece of the polar
alignment scope, turn the polar alignment scope body so that each of
the position scale for Tau Octantis and Chi Octantis come to the closest
to actual Tau Octantis and Chi Octantis respectively.
The numbers 15 and 40 on the position scales for Tau Octantis and Chi
Octantis show the years 2014 and 2040 respectively.
