Sighting - Nikon DTM-502 Series Instruction Manual

2-6. Sighting

"Sighting" refers to the aiming of the telescope at
the target, bringing the target image into focus,
and aligning it with the center crosshairs of the
reticle.
WARNING
Never view the sun through the telescope. Doing so may cause the
loss of your eyesight.
Notes on sighting are as follows:
• Diopter Adjustment
NOTE
Direct the telescope towards a blank area, such as the sky or a piece of
paper. Looking through the eyepiece, rotate the diopter ring to bring
the reticle crosshairs into sharp focus.
• Elimination of Parallax
Rotate the focusing ring to bring the target image into focus on the
reticle crosshairs. Move your eye vertically and laterally to see if the
target image moves in relation to the reticle crosshairs. If the target
image does not move, there is no parallax. If it moves, rotate the
telescope focusing ring to eliminate the parallax.
