2. Remove the counterweight safety screw on the bottom
end of the counterweight bar by turning it counterclock-
wise. This screw prevents the counterweight from falling
off the mount in the case the counterweight locking screw
comes loose.
3. Loosen the locking screw on the side of the counterweight.
4. Slide the counterweight over the counterweight bar and
move it about halfway up the bar.
5. Tighten the locking screw on the side of the counterweight
to hold it in place.
6. Replace the counterweight safety screw.
Tip: The hole in the center of your counterweight is slightly
larger on one side. When you slide the counterweight
onto the counterweight bar, make sure that the smaller
hole is facing the equatorial head. This allows you to
slide the counterweight over the safety screw at the
bottom of the counterweight bar in case you need
a little bit more adjustment to balance additional
accessories mounted on your optical tube. The smaller
hole prevents the counterweight from completely
sliding over the safety screw.
Attaching the Hand Control Holder
The Advanced VX telescope models come with a hand
control holder that attaches to a tripod leg. The hand control
holder comes in two pieces: the leg clamp that snaps
around the tripod leg and the holder which attaches to
the leg clamp. To attach the hand control holder:
1. Place the leg clamp up against one of the tripod legs
and press firmly until the clamp wraps around the leg.
2. Slide the back of the hand control holder downward into
the channel on the front of the legs clamp until it snaps
into place.
Attaching an Optical Tube to the Mount
The telescope attaches to the mount via a dovetail slide
bar, which is mounted along the bottom of the telescope
tube. Before you attach the optical tube, make sure that the
declination and right ascension clutch knobs are tight and
the counterweight(s) are securely installed. This will ensure
that the mount does not move suddenly while attaching the
telescope. To mount the telescope tube:
1. Loosen the two mounting screws on the side of the
telescope mounting platform. This allows you to slide
the dovetail bar onto the mount.
2. If your telescope is equipped with one, remove the safety
screws located beneath the dovetail bar.
3. Slide the dovetail bar on the telescope tube into the
mounting platform of the mount. Slide the telescope so
that the back of the dovetail bar is close to the back of
the mounting platform.
4. Tighten the mounting screws on the side of the mounting
platform to hold the telescope in place.
Now that the optical tube is securely in place, the visual
accessories can be attached to the telescope. This is
covered in detail in the section of this manual dealing
with the use of optical tubes.
Using the Dual Saddle Plate
Your Advanced VX mount comes with a dual saddle plate,
allowing you to use any optical tube using a 1.75” V-plate
dovetail bar (Synta, Vixen) or the wider 3” (75mm) D-plate
style dovetail bar (CGEM, CGX, CGX-L).
Your Advanced VX mount should already be set up to use
the smaller V-plate. To convert the mount for use with the
larger D-plate, simply remove the two bolts from the left
side of the dovetail saddle using a 6mm Allen-key.
Remove the two hand knobs and transfer them over to the
threaded holes you just uncovered.
