CELESTRON - CGEM DX 1400 Schmidt-Cassegrain 14" Computerized Telescope (#11101)

The Celestron CGEM DX 1400 Schmidt-Cassegrain Computerized Telescope includes both the 14" OTA and the CGEM DX Equatorial Mount. The optical tube assembly is a classic Schmidt design, meaning it uses aspects and features from both refractors and reflectors. The use of a correcting lens and a primary mirror system results in a focal ratio of around f/11,but can be reduced to with an optional reducer. It is also coated with the StarBright XLT coatings from Celestron which improve light reflectivity.

Equatorial mounts are almost always preferred by professional astrophotographers, mainly because of their adjustable altitude and azimuth features as well as payload capacity. The Celestron DX Equatorial Mount is suitable for astrophotography, holding optical tubes of up to 40 pounds! The All-Star Polar Alignment makes it easy for the user to precisely align the mount to the north celestial pole for accurate slewing and tracking of stars. This comes in especially handy for astrophotography. In order to precisely align the mount, the user must follow the standard two star alignment and then select a star on the hand controller to slew to. Once polar align is selected, the telescope with point to the coordinates assuming the mount was already polar aligned. Once the user centers the star by adjusting the azimuth and altitude, the mount is aligned to the north celestial pole. The tracking in this mount is another great astro-imagining feature because the CGEM DX tracks past the meridian to render the clearest images possible.



  • 14" Schmidt-Cassegrain telescope
  • New CGEM DX Computerized Equatorial Mount
  • FASTAR compatible optical tube for f/2 imaging
  • Schmidt-Cassegrain mechanism that moves the primary mirror to adjust focus is supported by two pre-loaded ball bearings, minimizing the "mirror flop" typical of bushing focus mechanisms
  • Celestron's premium StarBright XLT coatings
  • 9x50 finderscope to help accurately find objects
  • Ultra sturdy 2.75 inch steel tripod with Accessory Tray
  • Star diagonal provides more comfortable viewing position when observing objects that are high in the sky


  • Secure power plug ensures that the mount's power source is not accidentally disconnected
  • 40,000 object database with over 100 user-definable objects and expanded information on over 200 objects
  • Proven NexStar computer control technology
  • New "All-star" Polar alignment uses any bright star for a quick and accurate Polar alignment
  • Software Features include: Mount Calibration, Database Filter Limits, Hibernate, five Alignment Procedures
  • Flash upgradeable hand control software and motor control units for downloading product updates over the Internet
  • Custom database lists of all the most famous deep-sky objects by name and catalog number: the most beautiful double, triple and quadruple stars; variable stars; solar system objects and asterisms
  • Permanent Programmable Periodic Error Correction (PEC) - corrects for periodic tracking errors inherent to all worm drives
  • Drive Motors - Low Cog DC Servo motor with integrated optical encoders offer smooth, quiet operation and long life. The motor armatures are skewed to minimize cogging which is required for low speed tracking
  • Internal Cable wiring for trouble-free setup and transportation
  • Designated six-pin RJ-12 modular jack, ST-4 compatible guide port
