11.3 Reticule of the telescope
Check
1. Aim at a target A from the telescope after leveling the
instrument the cross wire on the reticule. Lock the instrument
with vertical and horizontal locking knob after aiming at A.
2. Rotate the vertical slow motion knob, move A point to the
edge of the field of view (A 'points).
3. If „ A‟ moves along the vertical line of the crosshair, but
is still in the vertical line as the left picture, the crosshair doesn't
need to calibrate. If A point deviate from vertical line center, as
the right picture, the crosshair is slant, so need to calibrate the
reticle.
Calibration
1. First, take down the reticule cover between telescope
eyepiece and focusing handwheel, and you can see four fixed
screw of the reticle bed (sees attached figure).
2. Unscrew the three fixed screw evenly with screwdriver ,
rotate the reticle around collimation axis, to make A point on the
vertical line of the reticle.
3. Tighten the screw evenly, test the calibration results with
the above methods.
4. Cover the reticule.
