[Target sighting by Manual focus]
q Loosen the telescope clamp and horizontal clamp screws.
w Point the telescope at the target using a collimator.
e Tighten the above two screws.
r Adjust the eyepiece.
t Look through the telescope and then rotate the AF ring and stop it where the
target can be seen clearly and the target image does not move in relation to
reticle even if your eye is vertically and horizontally moved.
y Aligh the reticle accurately on the target using telescope and horizontal
tangent screws.
The AF ring rotation "clockwise" makes it possible to focus on closer objects
and "counterclockwise" will focus on further objects.
