Adjusting the Cylinder Assembly During Telescope Installation
The side of the fork opposite the declination gear incorporates a sliding cylindrical assembly that can
adjusted to match the width of the telescope. Ideally, the distance between the two mounting plates
attached to the fork is identical to the distance between the two scope plates that are mounted on the
telescope. The adjustable cylinder assembly provides ample adjustment if the distances between the
two are not exact.
The ½-13 setscrew clamp located on the bottom half of the fork (with the arms orientation from Figure
45) can be loosened (see Figure 46) to permit lateral motion of the cylinder assembly as shown in Figure
47.
1. Loosen the setscrew clamp so that cylinder assembly can be adjusted freely.
2. Orient the fork mounting plates with the dovetail facing into the arms and the holes facing to
the outside as shown in Figure 46, Figure 47 and Figure 48.
