IntelliScope port (Figure 25). Thread the knob into the
optical tube’s altitude bearing until the knob pulls the alti-
tude bearing against the CorrecTension pads on the inte-
rior surface of the left panel.
3. Take the other tensioning knob and push it through the alti-
tude encoder’s aluminum shaft (now protruding from the
right side panel) and into the tube’s other altitude bearing
(Figure 26). You can move the altitude encoder up-and-
down a bit with the knob in order to have the knob’s shaft
line up with the threaded hole in the tube’s altitude bear-
ing. Make sure this knob is always fully tightened, or else
the IntelliScope’s altitude encoder will not work properly.
The telescope tube is now connected to the base. If you wish
to remove the optical tube from the base, you will first need to
unthread and remove both the tensioning knobs.
installing the Finder scope and Eyepieces
These accessories can be found in the optical tube assembly
box.
1. To install the finder scope into its bracket, first remove the
O-ring from the bracket and place it over the body of the
finder scope until it seats into the groove in the middle of
the finder. Unthread the black nylon alignment screws on
the bracket until the screw ends are flush with the inside
diameter of the bracket. Slide the eyepiece end (narrow
end) of the finder scope into the end of the bracket’s cyl-
inder opposite the alignment screws while pulling the
chrome, spring-loaded tensioner on the bracket with your
fingers (Figure 27). Push the finder scope through the
bracket until the O-ring seats just inside the front open-
ing. Release the tensioner and tighten the two black nylon
screws a couple of turns each to secure the finder scope
in place. The tips of the tensioner and nylon screws should
seat into the wide groove on the finder scope’s body.
2. Insert the base of the finder scope bracket into the dovetail
holder located adjacent to the telescope’s focuser (Figure
28). Lock the bracket into place by tightening the thumb
screw on the dovetail holder.
3. The final step in the assembly process is to insert an eye-
piece into the telescope’s focuser. First, take the cover
cap off the focuser drawtube. To use the 2" Deep View
eyepiece, loosen the two thumb screws on the 2" adapt-
er (on the end of the focuser drawtube) and remove the
1.25" adapter. Then place the 2" eyepiece directly into the
Figure 27. Pull-back on the tensioner and slide the finder scope
into its bracket until the O-ring is seated in the bracket ring.
