For a completely automated GoTo system, the C91/4-SGT (#11046) comes mounted on the CG-5GT 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 C91/4-SGT allows you to remotely slew your telescope to desired objects quickly and accurately. The 9 1/4" was specifically designed for visual infinity focus when using 2" eyepieces and has an optimized baffle system to benefit astrophotography by minimizing vignetting at the edge of the field of view. Its longer primary focal length and lower magnification secondary mirror contribute to a flatter field of view at the focal plane and helps to further reduce optical aberrations. No matter at what level you are starting out, this precision instrument is design to expand as your interest in astronomy grows.
CG-5 Mount, Precision engineered for stability.
The new German Equatorial mount has precision worm gears on both axes for extremely smooth stability. Th e 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 tha t offer excellent damping characteristics for more stable views. The CG-5 also h as 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. |
