Product description:

The EdgeHD optical system combines all of the compact power popularized by the SCT with an improved high definition optical system for wide field, astrograph quality images. As a visual instrument, EdgeHD optics deliver pinpoint images even with your widest field eyepiece. You can search for all of the Messier Catalog objects, and see hundreds of other NGC, IC and Caldwell objects with amazing clarity. For astro imaging, EdgeHD optics produce aberration-free images across your favorite CCD or DSLR camera. All EdgeHD optics are designed to produce an extremely flat focal plane precise enough to match the strict tolerances of the largest commercial CCD detectors, allowing stars to be in tight focus to the very edge of the chip.

CGX Equatorial Mount and Tripod:

For eight years, Celestron’s workhorse CGEM mount lineup has been the German Equatorial backbone for telescopes ranging from 6 to 11 inches of aperture. Since that time, many more astro-imagers and planetarium controlled setups have emerged as backyard telescope technology has evolved. Celestron’s engineering team applied their years of experience designing German Equatorial mounts to the all-new CGX EQ, a culmination of all the advancements made to our technologies, value, and ease-of-use.

All-new design:

  • Sturdier and more rigid with quicker dampening time
  • 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
  • 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
  • Adjustable EQ head position to optimize center of gravity over the tripod and fully utilize the increased 3º-65º latitude range
  • Dual-fit CG-5/Vixen and CGE/Losmandy dovetail saddle

New improved tripod:

  • 2" steel legs with height index marks for quick leveling
  • "Jack of all trays" can hold three 1.25" eyepieces, two 2" eyepieces, your smartphone, or other accessories
  • Tripod legs can be collapsed with accessory tray installed for faster setup and transport


  • All-new 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)

The new CGX was designed to better support your telescope for both visual and astro-imaging pursuits. Key design goals included a lower profile EQ head, which provides a more compact and therefore more stable setup; a better drive system; remote operation-friendly with home and limit optical sensors; easier polar alignment adjustments; and better cable management. In addition to that, we’ve made mechanical and ergonomic improvements throughout to make the mount sturdier, easier to use, and transport. The CGX is our new Equatorial backbone to support a wide range of telescopes.
