Recognized For Superior Stability
An improved Super HD Tripod supports the CGE mount. This fully
extendable tripod is made from the finest cold rolled carbon steel
and can be raised to a height of 124cm (50"). The tripod uses a dual leg
support for maximum rigidity with an upper leg brace to provide
an outward preload and a lower leg brace providing inward tension.
CGE Equatorial Mounts Can Easily be Balanced on Both Axes
Balancing the weight of camera equipment and other visual accessories
is accomplished by simply sliding the counterweight for Right
Ascension and moving the optical tube along its dovetail mounting
for Declination. This means that no additional weight needs to be
added to balance the telescope when additional accessories are added.
Clearance For Accessories
CGE mounts support their tubes at a single contact point allowing the
tube to move freely around its polar axis without making contact with
the telescope’s mount. This is particularly useful when adding
photographic and CCD instruments that extend from the rear of the
telescopes.
GPS Compatible
All CGE mounts are compatible with Celestron’s CN16 GPS accessory
(Item #93967). Combine the GPS and built-in Hibernate mode and these
mounts will keep track and remember their exact location and time
without the need to re-enter the information into the remote hand
control.

Computerised
|
- 40,000 object database with 400 user-definable objects and expanded information on over 200 objects.
- Proven NexStar computer control technology.
- GoTo system is precision accurate to 1.5 arcminutes.
- Software Features include: Compass Calibration, Polar Alignment routine, Database Filter Limits, Hibernate, Auto North and Level, Quick Align, and user-defined slew limits.
- Flash upgradeable hand control software and motor control units for downloading product updates over the Internet.
- Custom database lists of all the most famous deep-sky objects by name and catalog number; the most beautiful double, triple and quadruple stars; variable star; solar systems; objects and asterisms.
- Permanent programmable periodic error correction (PEC) - corrects for periodic tracking errors inherent to all worm drives.
- Precision Bronze Worm Gear - 32 pitch, 5.625" pitch diameter, 180 tooth bronze gear manufactured in the U.S.A. by W. M. Berg, Inc. Manufactured to AGMA Quality Class 10 standard, which minimizes total composite error and backlash.
- Drive Motors - Made in the U.S.A., Pittman® LO-COGT brush-commutated DC motors offer smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging which is required for low speed tracking.
- Bearing and Shaft - Stainless steel worm shaft has 0.4375 pitch diameter and is preloaded with two ball bearings. The worm is made from a single piece of steel (rather than a two-piece worm-and-shaft assembly) to minimize run-out, which is a source of PE.
- 12VDC Servo Motors with integrated optical encoders with 0.11 arcsecond resolution.
- No-slip clutch system for pointing precision.
- Autoguide port, PC port and auxiliary ports located on the electronic pier for long exposure astrophotography.
- Double line, 16-character Liquid Crystal Display Hand Control with backlit LED buttons for easy operation of goto features.
- RS-232 communication port on hand control to control the telescope via a personal computer.
- Includes NexRemote telescope control software, for advanced control of your telescope via computer.
- GPS-compatible with optional CN16 GPS Accessory (93967).

Auto-Guiding
|
You can use this mount as part of an auto-guiding system for astrophotography.
Other components that you will need are:
- A computer to control the telescope mount (e.g. Windows 2000/XP/Vista).
- Auto-guider control software such as:
-
AstroArt is a good commercial solution, because it can control multiple
CCD cameras (e.g. for guiding and imaging) and it can be used for image stacking, processing,
photometry, etc.
- A computer interface and cables to connect the computer to the telescope mount:
- Shoestring GPUSB auto-guider USB Connectivity Kit, through the computer's USB port.
- Shoestring GPINT-PT auto-guider Parallel Port Connectivity Kit, through the computer's Parallel Port.
- CCD camera for auto-guiding :
