Celestron CGX 925 Schmidt-Cassegrain Telescope


The Celestron CGX 925 SCT Telescope is a 235 mm (9.25-inch) Schmidt-Cassegrain Telescope on a CGX Mount and is capable of gathering 1127X more light than the human eye. It has a precise f/10 optics that offers an incredible 0.49 arc seconds of resolution spread out over a 0.53-degree angular field of view. With a limiting magnitude factor of 14 and a practical magnification limit of 555X, it delivers remarkable planetary and lunar views.

When sky permits, you can expect to see details like delicate divisions in Saturn's ring structure, details on Mars, and follow Jupiter events, (like shadow transits and Great Red Spot appearances,) with ease. Star clusters will transform into well-resolved facets, galaxies will take on structure, and difficult double stars will yield their companions. With a low-end magnification limit of 34X, just add a wide field eyepiece, or open both eyes wide with Celestron Stereo Binocular Viewers, and enjoy panoramic vistas of extended nebulae and sweep the heavens for every last photon!

Celestron CGX 925 SCT Features

  • Large Altitude and Azimuth adjustment knobs for quick and easy procedures and adjustments.
  • All-Star system allows you to choose any bright star from the NexStar hand control, while the software calculates and assists with polar alignment.
  • The CGX-925 database will provide over 40,000 objects, 100 user-defined programmable objects and enhanced information on over 200 objects for your celestial viewing pleasure.
  • The CGX is simply more responsive, with spring-loaded worm gears and belt drives that minimize backlash. Internal cabling means power and accessory ports do not move with the mount, and there are also home and limit switches, as well as internal hard stops for both RA and Dec to prevent cable wrap and tripod strike.
  • A clear window built into the motor covers, letting you keep an eye on the pulleys and belts.


  • Focal Length of Eyepiece: 25 mm (.98 inches).
  • Magnification of Eyepiece: 94x.
  • Finderscope: 6x30.
  • Star Diagonal: 1.25-inch Star Diagonal.
  • Optical Tube: Aluminum.
  • Lowest Useful Magnification: 34x.
  • Resolution (Rayleigh): 0.59 arc seconds.
  • Secondary Mirror Obstruction by Diameter: 36%.
  • Secondary Mirror Obstruction by Area: 13%.
  • Optical Coatings: StarBright XLT.

    CGX Computerized Equatorial Mount Features 

    • 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.
    • 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.
    • Celestron PWI developed in conjunction with PlaneWave Instruments 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 astro-imaging.
    • Wider tripod stance for improved stability. 


    • Height adjustment range (includes mount and tripod): 1200.15 - 1968.5 mm (47.25 - 77.5 inches).
    • Tripod Leg Diameter: 50.8 mm (2-inch) Steel tripod with graduated markings on the lower section.
    • Accessory Tray: Yes.
    • Tripod Weight: 19.2 pounds (8.7 kg).
    • Weight of Counterweights: 2 x 11 pounds.
    • Slew Speeds: 9 slew speeds
    • Tracking Rates: Sidereal, Solar and Lunar.
    • Dovetail Compatibility: Dual saddle plates (Vixen and CGE saddle).
    • Motor Drive: Low cog DC servo motors.
    • Alignment Procedures: 2-Star Align, Quick Align, 1-Star Align, Last Alignment, Solar System Align.
    • Computer Hand Control: Double line, 16 character Liquid Crystal Display; 19 fiber optic backlit LED buttons, USB 2.0 port for PC connection.
    • Database: 40,000+ objects, 100 user-defined programmable objects. Enhanced information on over 200 objects.
    • Software: PWI Telescope Control Software, Starry Night Special Edition.

    Included Technology

    All-Star Polar Alignment

    Get ready for a night of astroimaging with your mount faster than previously thought possible with All-Star Polar Alignment. This innovative software solves the time-consuming problem of trying to pinpoint the North Celestial Pole.

    Compatible Technology


    The new Lithium Phosphate (LiFePO4) battery chemistry has significant advantages over other battery chemistries, great for those Astronomers on the go.

    Starsense Technology

    Celestron’s patented StarSense Technology makes it easier than ever to locate objects in the night sky, even if you’ve never used a telescope before. Turn it on and push ‘Align.’ In about three minutes, you’re ready to observe!


    WiFi technology encircles the globe in a web of connectivity, knowledge, and information. Now, Celestron is using that same technology to allow stargazers to connect to the night sky and enhance their experience of the cosmos in fun and unique ways.
