4. Next, thread the second latitude adjustment T-bolt (D) into
the hole in the mount base. (One T-bolt comes pre-installed;
the other one you must install yourself.)
Figure 3
shows the
two installed latitude adjustment T-bolts.
5. Install the counterweight shaft by threading it into the coun-
terweight shaft collar. (
Figure 4A
).
6. Now remove the safety stop at the end of the shaft and
slide the counterweight onto the shaft (
Figure 4B
). You may
have to loosen the counterweight lock knob to allow the
weight to slide onto the shaft. Once the counterweight is on
the shaft, replace the safety stop.
7. Attach the two slow-motion cables to the RA and Dec gear
shafts by threading the collar on the gear shaft onto the
cable until tight (
Figure 5
).
The EQ mount is now fully assembled. To install the optical
tube on the mount, proceed through the following steps.
8. Ensure that the right ascension and declination lock knobs
(
Figure 6
) are tightened so that the mount won’t swivel
accidentally when you’re attaching the tube rings or the
optical tube. And of course make sure the counterweight is
installed on the counterweight shaft.
9. Back out the two saddle clamp knobs enough to allow the
dovetail bar to seat properly. Then lift the optical tube and
set the dovetail mounting bar into the mount’s saddle.
10. When the dovetail bar is seated in the saddle, tighten the
saddle clamp knobs until tight.
11. One of the two tube rings has a piggyback camera adapter
on top (the knurled silver ring and thread); it can be used to
mount a camera for “piggyback” astrophotography.
Final assembly includes attaching the eyepieces and finder-
scope
12. The 1.25" visual back should be threaded onto the end of
the focuser drawtube (
Figure 7
).
13. Eyepieces can then slip into this visual back and are
secured by gently tightening down the eyepiece setscrew
on the side of the visual back. See the section at the end of
this manual for eyepiece selection.
