Reference : How to Collimate
1 Point the telescope toward the light. Turn the diopter ring and adjust the diopter so that the cross
hairs are clearly observed.
(Turn the diopter ring toward you first and then backward to focus.)
2 Aim the target at the peak of the triangle mark of the sighting collimator. Allow a certain space
between the sighting collimator and yourself for collimating.
3 Focus the target with the focusing knob.
*If parallax is created between the cross
hairs and the target when viewing
vertically or horizontally while looking
into the telescope, focusing is incorrect
or diopter adjustment is poor.
This adversely affects precision in
measurement or survey. Eliminate the
parallax by carefully focusing and using
diopter adjustment.
