Focusing telescope
1. Aim telescope against a
bright background (e.g. white
paper).
2. Turn eyepiece until reticule is
sharp-focussed and deep
black. Now the eyepiece is
adapted to your eye.
3. Aim telescope on staff using
the optical sight.
4. Turn focussing knob until
image of staff is sharply
focussed. If the eye is moved
up and down behind the
eyepiece the image of the staff
and the reticule may not be
displaced against each other.
For possible centring over a
ground point:
1. Attach plumb bob.
2. Loosen central fixing screw
slightly and shift instrument
parallel on tripod until the
plummet is exactly over the
point.
3. Tighten central fixing screw.
