Basic Information about the CGE Pro Series
In January of 2009, Celestron introduced a new line of computerized
scopes - the CGE Pro Series. CGE Pro is a step up on capacity and stability
from the original CGE series. Utilizing a NexStar hand control, the
CGE Pro
series consists of a German equatorial mount (GEM) on a steel-legged tripod. The series includes 9 1/4, 11
and 14 inch SCT models. The 14 inch model is also available with a
Fastar optical tube making it compatible with Starizona's
HyperStar system. The mount
is also sold without an optical tube. The computerized hand control is a version of the NexStar hand control
with the latest GEM-specific firmware. This hand control responds to the same
PC commands (via the RS-232 port on the bottom) as other NexStar-driven
scopes and thus could be used with any program offering a setting for
the NexStar GPS, for example. The mount includes a real-time clock
to keep the date/time settings required for alignment and can also use the CN-16 GPS module for precise
time and location information. The mount also includes a standard autoguider port.

The CGE Pro series provides a very stable platform for a wide
variety of optical tubes. It is an excellent platform for both visual and
photographic work and is an excellent choice for a permanent observatory
setup. For those looking for a more stable
astrophotography platform, particularly for imaging with a larger SCT
optical tube with many accessories, the CGE Pro is recommend over the CGE
and CGEM.
