Preparing The Telescope For Operation - Orion Observer 80ST Instruction Manual

Thread a leg lock thumbscrew onto each tripod leg as
shown, being careful not to overtighten.
screw seats in the groove of the gear shaft, as shown in
Figure 12, then firmly tighten the thumbscrew. If there is
a small rubber ball on the end of the shaft, you will have
to remove it in order to attach the cable. Also note that,
depending on your preference, you can attach the cable to
either the left or right side of the right ascension gear shaft.
Now the mount is properly attached to the tripod and outfitted
for use (Figure 13). Next, you'll attach the telescope optical
tube to the mount.
11. Remove the wing nuts and washers from the optical tube
mounting bolts that are pre-installed on the underside
of the telescope optical tube (R). Then lay the telescope
optical tube assembly onto the saddle plate (Figure 14),
passing the mounting bolts through the holes in the saddle
plate. Then place a washer on each bolt and re-attach the
wing nuts until tight. Be sure the focuser portion of the
optical tube is on the same side of the saddle as the slow-
motion control cable in Declination, as in Figure 14.
12. To attach the red dot finder scope (S) to the optical tube,
orient the finder scope as shown in Figure 15 and slide
the bracket foot into the finder scope base until it clicks.
(To remove the finder scope, press the small tab at the
back of the base and slide the bracket out.)
13. Insert the star diagonal (W) into the focuser drawtube and
tighten the two thumbscrews on the drawtube collar (Figure
16). Then insert the 25mm eyepiece (U) into the diagonal
and secure it by lightly tightening the thumbscrew on the
diagonal.
The telescope is now completely assembled! Before it can be
effectively used, however, there are a couple of things to do to
prepare the telescope for operation.

for Operation
Aligning and Using the Red Dot Finder Scope
Accessory tray Screw head
Figure 5.
Attach the accessory tray to each of the tripod three
leg brace supports using the provided hardware.
The included red dot finder scope (Figure 17) makes pointing
your telescope almost as easy as pointing your finger! It's a non-
magnifying aiming device that superimposes a tiny LED red dot
on the sky, showing exactly where the telescope is pointed. It
permits easy object targeting prior to observation in the higher-
power main telescope.
Before you can use the red dot finder scope, you must remove
the small plastic tab sticking out from the battery compartment
(Figure 17). Doing so will allow the pre-installed 3V CR-2032
