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'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 adjust-
ing 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)
