Celestron CGX-L Mode D'emploi page 7

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 and 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 Counterweight(s)
Remove the stop nut at the end of the counterweight shaft,
add the counterweight(s), then thread the stop nut back on
Keep the Counterweight shaft pointed downward
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 handle labeled
"Celestron" (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-L fits the large Celestron CGE-style dovetail
and the smaller CG-5-style dovetail, also common to the
Losmandy D(1) and Vixen-style(2) 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 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 (Figure 6)
