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 1/4inch was specifically designed for visual infinity focus when using 2inch 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. 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. The Advanced GT Series telescopes include these high performance features: GPS-compatible with optional CN16 GPS Accessory (#93966). Proven NexStar computer control technology. RS-232 communication port on hand control to control the telescope via a personal computer. Auto guider port for long exposure astrophotography. 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 catalogue number; the most beautiful double, triple and quadruple stars; variable star; solar systems; objects and asterisms. Double line, 16-character Liquid Crystal Display Hand Control with 19 fibre optic backlit LED buttons. DC Servo motors with encoders on both axes. The CG-5 GT computerized mount features Celestron's sleek integrated design.
