The new Advanced Series family of computerized GoTo telescopes was designed to offer the novice or more advanced user a selection of models with the features and quality that serious amateurs can appreciate. These scopes come on NEW heavy-duty German Equatorial mounts with NEW ultra-sturdy 2" stainless steel legs and center tray for superior rigidity and vibration dampening. The Advanced Series comes in refractor, reflector and Schmidt-Cassegrain models. The refractor models range from a 4" to an impressive 6" aperture. For even more light gathering power there are 6", 8" and a NEW 10" Newtonian Reflector. There are also 5", 8" and 9 1/4" Schmidt-Cassegrain optical designs that feature Celestron's precision matched and hand-figured optical systems.
CG-5 Mount - Precision engineered for stability.
Our new German Equatorial mount has precision worm gears on both axes for extremely smooth stability. The key element that makes this system the most stable in its class is the NEW heavy-duty tripod with larger and more substantial legs that offer excellent damping characteristics for more stable views. The CG-5 also has a convenient latitude scale for easier alignment and an optional polar finder scope for the ultimate in precision alignments.
GoTo convenience and GPS compatibility for precision accuracy.
We are proud to offer the GT versions
of the Advanced Series on a computerized GoTo version of Celestron's sturdy
CG-5 mount. Couple this solid mount with the included computerized control system
to utilize many of the same functions and features-like the NexStar computer
control system and an Autoguider port for long exposure deep sky astrophotography-as
Celestron's most advanced GoTo telescopes. GoTo models are also upgradeable
to GPS with the optional CN16 GPS Accessory (#93963) allowing your telescope
to pinpoint your position on the earth, the date and time, making the alignment
process faster and easier than ever before! These GoTo versions of the Advanced
Series also come loaded with new software features and over 40,000 database
objects. Capable of holding over 35 lbs of payload and slewing at 4º per
second, you will be able to instantly point to any of the celestial objects
in the database.
The Advanced GT Series telescopes include these high performance features:
- GPS-compatible with optional CN16 GPS Accessory (#93963)
- Proven NexStar® computer control technology
- RS-232 communication port on hand control to control the telescope via a personal computer
