4.9. Focusing and Collimating
General focus and collimate process:
1. Diopter adjustment
Looking through telescope at a brigh monochromatic background. Turn the eyepiece’s diopter ring
clockwise to the end, observe the reticle, slowly turn the ring counterclockwise until the reticle image is
sharp and clear.
2. Rough targeting
Release the horizontal and vertical lock triggers counterclockwise, rotate the telecope to aim for the
target with the optical sight, observe from the eyepiece to confirm that the target is in the field of view,
then lock both triggers clockwise.
3. Focusing
Observe the target from the eyepiece, slowly turn the focusing ring until the target image is sharp and
clear.
4. Precisely collimating
Observe the target from the eyepiece, adjust the horizontal and vertical drive to aim the reticle
precisely at the center of the target. The final direction of rotation of the drives are always
recommended to be clockwise.
5. Repeat 3 and 4 until the target and reticle image are all clear, and both centers are precisely aligned.
6. Start measuring.
