    The CGX 700 Mak is a specialized instrument designed for detailed, high-contrast views of smaller celestial objects like planets, and up-close views of the lunar surface (including craters and maria). Maks are also well suited for hunting smaller, fainter, deep sky objects such as globular clusters and planetary nebulae.  Astronomers located in urban areas will highly appreciate the Mak’s ability to bring out more contrast in celestial objects.

    Transporting the entire telescope package to a dark site is not a problem either. The kit disassemble into separate manageable pieces with no tools required!

    Maksutov-Cassegrain Optical Design:

    As a catadioptric/cassegrain telescope, the light coming through a Mak passes through the corrector lens to the primary mirror and back to a spherical secondary mirror before it hits your eyepiece. Images are bright, sharp, and virtually free of chromatic aberration! Due to the secondary "spot" of reflective coating applied directly to the inside of the corrector plate, the telescope does not require frequent collimation like a Schmidt-Cassegrain. The spot is also significantly smaller than a traditional Schmidt-Cassegrain secondary mirror, giving the Mak its signature high-contrast views.

    Note that you will need to allow more time for the larger, heavier Maksutov corrector plate to cool down and adjust to the ambient air temperature compared to a SCT of the same aperture. 

    CGX Mount and Tripod Features:

    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

      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
