    Celestron's CGX Equatorial 1100 HD combines the innovative CGX computerized equatorial mount with its acclaimed EdgeHD optical system.

    With the optical tube assembly (OTA) weighing only 13kg, this telescope is a great companion for trips. This CGX instrument has 89% more light-gathering power than an 8" telescope and 40% more than a 9.25". For astrophotography, the CGX mount offers a sturdier platform with a smoother, heavy-duty belt drive system. It also features advanced software and new electronic and ergonomic features for the best starry night adventures! 

    See the Universe in HD | True Astrograph Quality:

    EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce off-axis star coma and provide an astrograph-quality flat focal plane all the way to the edge of the field of view.

    • Experience amazing optical performance with EdgeHD’s flat-field and coma-free optics for pinpoint stars all the way to the edge of today’s largest imaging sensors and widest eyepieces
    • Aluminum optical tube with tube vents featuring an integrated 95-micron mesh filter allows hot air to be released from behind the primary mirror. Sturdy mirror support knobs hold the mirror in place and reduce image shifts during imaging
    • Versatile design accommodates 3 focal ratios: native f/10, f/7 with the addition of a focal reducer, or ultra-fast f/2 imaging with a removable secondary mirror and third-party accessories

    CGX Mount and Tripod Features | Improved Performance:

    The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits. It is Celestron's new equatorial backbone to support a wide range of telescopes.

      • Sturdier and more rigid with quicker dampening time
      • Increased load capacity to 25kg
      • Improved motors provide more torque, better slewing and tracking under heavy loads
      • Heavy duty belt-drive system minimizes backlash while providing smooth motor operation under heavy loads
      • Spring-loaded brass worm wheel and stainless steel worm gear reduce friction and provide optimum gear mesh
      • Internal cabling for worry-free remote operation. Power input and accessory ports remain stationary while the mount slews to avoid snags
      • Internal hard stops for both axes prevents cable tension and tripod strike
      • Internal optical sensors on both axes for simple and safe remote operation
      • Home sensors allow the mount to always start in the index position regardless of orientation before a power reset
      • Limit sensors automatically shut off slewing or tracking before reaching the hard stop fail safe
      • Brand new control software developed for professional level control operation and imaging
      • Software includes multi-point mount modeling for extremely precise pointing accuracy and many more additional features for remote astroimaging
      • Wider tripod stance for improved stability
      • Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3°-65° latitude range
      • Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle

      Improved tripod includes:

      • 2" steel legs with height index marks for quick leveling
      • "Jack of all trays" to hold three 1.25" eyepieces, two 2" eyepieces, your smartphone, or other accessories
      • +20° of additional tracking past the meridian on either side
      • Tripod legs can be collapsed with accessory tray installed for faster setup and transport

      Mechanical features:

      • Mirror clutches - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
      • Tube vents - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
      • Fastar versatility - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.

      Improved Ergonomics:

      • Two handles for easy pickup and transport
      • New ergonomically designed dovetail clamping knobs
      • Innovative and improved polar alignment adjustment system
      • All-new ergonomic adjustment knobs with reduced friction for smooth and easy positioning under full loads 
      • Optional add-on polar axis finderscope


      • NexStar+ hand control with USB port
      • Two AUX accessory ports to support wireless/WiFi alignment and operation with StarSense AutoAlign and SkyPortal WiFi Module accessories (sold separately)
      • USB 2.0 port, used to connect directly to PC with included software
      • Autoguider port
      • PPEC ready
      • Threaded 12VDC power input barrel connector
      • Internal Real Time Clock (keeps time and site information saved
