Inspection and Adjustment
Collimation Error C = (HRnorm - HRrev ± 180°)/2
If C <10", no adjustment is required; if C >10", adjustment is required.
Adjustment
1. Adjust the horizontal fine motion in the reverse position of the telescope so that the
reverse reading HRrev
′
= HRrev + C.
2. Remove the protective cover of the reticle of the telescope and adjust both the left and
right adjusting screws so that the vertical hair of the reticle coincides with object A.
3. Repeat the steps in "Inspection" and "Adjustment" until acceptable condition is
reached.
