Polar Align The Mount; Basic Usage - Celestron CGX-L Mode D'emploi

Attach the Hand Control Holster
Wrap the hook & loop strap and holster around the tripod
leg and place the hand control in the holster
Plug in the Hand Control
Plug the supplied NexStar+ hand control into one of the
Aux ports
Warning: Do not plug the hand control into the
Autoguide Port. Damage to the mount or hand control
could occur. Similarly, do not plug an autoguider cable
into the Aux port or damage could occur.
Home Position
The mount is in the "home" position when the counterweight
shaft is pointing downward, and the telescope is pointing
along the polar axis of the mount as pictured in (Figure 7)
The mount's internal switches will take the mount to its
home position when you power it on (more on that in
"Basic Usage"), but you can still manually position it before
powering on the mount Simply unlock the two lock levers,
and move the telescope to the desired position

Polar Align the Mount

The computerized go-to is capable of locating objects
even if the mount is not perfectly polar aligned However,
polar alignment is necessary to achieve the best
tracking accuracy of your mount, and it's essential to
astrophotography When polar aligned, an Equatorial mount
tracks the sky in one motion, keeping the object centered in
the eyepiece or camera
CGX-L's polar alignment system consists of an altitude
adjuster and azimuth adjuster (Figure 8)
An optional polar alignment scope is available from Celestron
and attaches to the mount The optional polar axis scope
does not pass through the R A axis because that area is used
for internal cabling If you are not using the optional polar
alignment scope, you can achieve a rough polar alignment
by sighting through the viewfinder of your telescope, and
adjusting the mount until you center Polaris in the eyepiece
of your telescope This will get you to within about three-
quarters of a degree within the North Celestial Pole (NCP)

Basic Usage

With your mount assembled and polar aligned, proceed to
startup the mount:
Powering the Mount
The CGX-L mount can be powered by the supplied car
battery adapter to a 12VDC battery source that can deliver
at least 3 amperes of current Or you may use an optional
AC adapter that delivers at least 3 amperes of current
