Description

The popular 6" Newtonian in the Advanced series is now available on our heavy-duty CG-5 computerized mount. The C6-NGT Newtonian scope uses diffraction-limited parabolic primary mirror for razor sharp star images across a wide field of view.  The optics of these heavyduty telescopes are manufactured to Celestron's uncompromising standards with star images that are classic textbook Airy disks.

Mounted on the Advanced GT Series computerized mount, this telescope has some high  performance software and hardware features.  Operated by our proven NexStar® computer control technology, the telescope has a 40,000+ object database with 100 user-definable objects and expanded information on over 200 objects. 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 stars; solar system objects and asterisms.

Using the RS-232 communication port on the hand control, you can control the telescope via a personal computer, and our new flash upgradeable hand control allow you to update your telescope's operating software via the Internet.  An Autoguider port is also included for astrophotography.  No matter at what level you are starting out, this precision instrument will satisfy your needs both visually and photographically.

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.
