Available again soon - The optics and mechanics of this fine C8-NGT telescope are manufactured to Celestron‘s uncompromising standards. The C8-N uses diffraction-limited parabolic primary mirrors for razor sharp star images across a wide field of view. These telescopes are mounted on the very rigid computerized CG-5 German Equatorial mount meaning it is ready for advanced visual or imaging applications right away. The larger aperture of this instrument means deep sky objects reveal far more detail than smaller models and resolving power on Solar system objects is increased.
A counterweight, latitude scale, setting circles, and slow motion controls on both axes are standard. Includes premium accessories including a 9x50 finderscope with bi-directional alignment screws and a spring loaded pivot support, 20mm Plössl 1-1/4" eyepiece, 2" focuser, accessory tray and more, so you have a fully capable telescope system right from the start.
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 400 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 star; solar systems; objects and asterisms.
Using the RS-232 communication port on the hand control, you can control the telescope via a PC and our new flash upgradeable hand controls allow you to update your telescope's operating software via the internet. An autoguider port is also included for astro imaging.
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.
