Roughly Polar Align the Mount
Before more weight is added to the mount and tripod,
roughly position the mount so that it’s pointing north
(or south if in the southern hemisphere), and set to your
latitude. Loosen the two altitude lock knobs, then turn the
altitude adjustment knob (Figure 1.1) until you are roughly
set to your latitude indicated on the latitude scale (Figure
1.2), then retighten the altitude lock knobs. The scale is
intended for rough polar alignment only. A more precise
polar alignment can be achieved later with the assistance
of the computerized hand control.
Add the Counterweights
Remove the stop nut at the end of the counterweight shaft,
add the counterweights, then thread the stop nut back on.
Keep the Counterweight shaft pointed downward.
(Figure 1.1)
Attach the Telescope to the Mount
1. Make sure both R.A. and DEC clutch levers are tightened.
2. Loosen the dovetail saddle lock knobs enough to allow
the dovetail to fit into the saddle. Note the arrow should
be pointing to the same side as the front handle (Figure 4).
3. Slide the telescope’s dovetail bar into the dovetail saddle
of the mount. Tighten the telescope in place with the two
lock knobs (Figure 5).
The CGX fits the large Celestron CGE-style dovetail and the
smaller CG-5-style dovetail, also common to the Losmandy D

and Vixen-style

dovetail.
1
Test fit your Losmandy dovetail bar before securing your
telescope to the mount. Sizes and dovetail angles across
different manufacturers can vary.
2
Test fit your Vixen dovetail bar before securing your
telescope to the mount. Be aware that some of the
Vixen-style dovetails are not flat and have different
heights along the bar. Depending on the length of the
flat, it can affect the fit onto the dovetail saddle of
the mount.
Balance the Mount
Right Ascension Axis: Carefully unlock the clutch lever for R.A.
and position the counterweight shaft so that it’s horizontal.
Without letting go of the telescope, check to see which side
the balance is in favor of. Slide the counterweights as needed
so the R.A. axis does not move when the clutch is unlocked.
Declination Axis: With the counterweight shaft still positioned
horizontally, carefully unlock the clutch lever for DEC
and check which way the optical tube is balanced (Figure 6).
Slide the optical tube forward or backward as needed to
achieve balance. For large and heavy telescopes, return
the telescope to the home position before loosening the
dovetail saddle lock knobs.
