About Celestron

For a completely automated GoTo system, the C8-SGT (#11026) comes mounted on the CG-5 GT computerized EQ mount and allows access to features like automatic star alignment capability and GoTo slewing to over 40,000 objects. Equipped with high speed motors and hand control, the C8-SGT allows you to remotely slew your telescope to desired objects quickly and accurately. 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
The 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 2" Stainless Steel heavy-duty tripod legs 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.

StarBright XLT high transmission optical system design:
There are three major components that make up the Star Bright XLT high transmission optical system design:
1. Unique enhanced multi-layer mirror coatings
2. Multi-layer anti- reflective coatings
3. High Transmission Water White glass.
These three components of the StarBright XLT coatings result in one of the finest coatings available.
