Center of the polar alignment scope’s field of view
(Center of the rotational axis of the equatorial)
Set Polaris to an approximate position that is corresponding to the year of your observation.
While looking into the eyepiece of the
polar alignment scope, turn the altitude
adjustment handles and azimuth
adjustment knobs so that Polaris comes
to the gap between the two segments of
the lines marked 2014 and 2040.
Note :
Correcting the position of Polaris with the altitude adjustment handles and azimuth
adjustment knobs.
Correcting the position of Delta UMi and 51 Cep with a rotation of the polar scope boy.
Repeat the procedures 11 and 12 until Polaris, Delta MUi and 51 Cep come to
the proper locations on the designated position scales respectively. Tighten
the azimuth adjustment knobs at both sides to finish the polar alignment.
As an illustration here, Polaris is set to the edge of the line on the side of 2014, and both Delta UMI and 51 Cep are 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)
