HOW TO USE
Now, Sigma Octantis gets out of place from the designated position but it is not necessary to correct for it at this stage.
Since there is no mark that points at the South Celestial Pole, you need to
match the polar axis of the POLARIE U with the S.C.P using the relatively dim
Octantis stars in the neighborhood.
As an illustration here, Sigma Octantis is set to the edge of the line on the side
of 2014, and both Tau Octantis and Chi Octantis are to set to the middle of
the curved lines of the position scale at the protruded edge on the side of 15
respectively. (In case of the year 2014)
Turn the polar scope body so that Tau Octantis comes near to the location of
the year 2014 on the scale. And then, Sigma Octantis will get out of position
from the gap between the lines.
Adjust the red�light illumination to be dimmer if the reticle is too bright to see the
5th magnitude Tau Octantis.
