- Observe the target with sighting collimator. Allow a
certain space between the collimator and yourself, if for
collimating.
- Focus the target with the focusing knob (pic.2).
Note:
If the focus of the telescope is incorrect the parallax is
created between the cross-hair and target when viewing
vertically or horizontally. This will affect precision in
measurement or survey. The parallax should be elimi-
nated by carefully focusing.
