alignment scope, turn the altitude adjustment
bolt and azimuth adjustment knobs so that
Polaris comes to the gap between the two
segments of the lines marked 2014 and
2040.
Correcting the position of Polaris with the altitude adjustment bolt and azimuth adjustment
knobs
Correcting the position of Delta UMi and 51 Cep with a rotation of the polar alignment
scope
Set Polaris to an approximate position that is corresponding to the year of your observation.

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)
