CGEM DX 1400 HD Computerized Telescope
Item #: 11004
Includes These Celestron Technologies
Description
The CGEM DX 1400 HD combines Celestron's newly designed CGEM DX Computerized Equatorial mount with its new EdgeHD optical system. With more than 60% more light gathering power than the 11" telescope, the CGEM DX 1400 is Celestron’s largest optical system in its class. Featuring our premium StarBright XLT coatings and 14" of aperture, this telescope gives you the brightest, clearest views whether observing planetary or deep-sky objects.
CGEM DX Mount
The CGEM DX™ mount is the newest member of our fully computerized Equatorial mount series capable of carrying Celestron’s high-end 11" and 14" optical tubes. The CGE PRO style, 2.75" leg tripod holds even our 14" optics securely while dampening vibration, which is ideal for both imaging and visual observing. Capable of holding 50 lbs of payload and slewing at 5° per second, you will be able to instantly point to any of the celestial objects in the database.
German Equatorial mounts are recognized for their rock solid stability, simple balancing and easy accessibility for attaching accessories. With sophisticated software features like the Hibernate function, the CGEM DX can maintain its star alignment night after night without needing to be re-aligned, making it an excellent choice for a permanent observatory facility.
Ergonomic Design - CGEM DX was designed to be ergonomically friendly with large Altitude and Azimuth adjustment knobs for quick and easy polar alignment adjustment. The internal RA and DEC motor wiring provides a clean look and an easy and trouble free set up.
Innovation - The CGEM DX series has a new innovative Polar alignment procedure called All-Star™. All-Star allows users to choose any bright star, while the software calculates and assists with polar alignment. Another great feature of the CGEM DX sure to please astroimagers, is the Permanent Periodic Error Correction (PEC) which will allow users to train out the worm gears periodic errors, while the mount retains the PEC recordings.
Performance - For objects near the Meridian (imaginary line passing from North to South), the CGEM DX will track well past the Meridian for uninterrupted imaging through the most ideal part of the sky. The CGEM mount has a robust database with over 40,000 objects, 100 user defined programmable objects and enhanced information on over 200 objects.
Power Management - Redesigned electronics deliver constant regulated power to the motors making them capable of driving the telescope even when not perfectly balanced. This allows the CGEM DX to have the payload capacity of that of much larger mounts without sacrificing smooth tracking motion and pointing accuracy across the entire sky.
New Optical Design
The EdgeHD optical system takes all of the compact power popularized by the Schmidt Cassegrain Telescope (SCT) and combines it 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 equally interesting NGC, IC and Caldwell objects with amazing clarity. For astroimaging, the 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 all stars to be in tight focus to the very edge of the chip.
EdgeHD WhitepaperThe Celestron Product Development team has released a whitepaper outlining the technology behind EdgeHD. This paper describes the development goals, design decisions, optical performance, and their practical realization in 8-, 9.25-, 11-, and 14-inch apertures. We include cross-sections of the EdgeHD series, comparative spot diagrams for the EdgeHD and competing “coma-free” Schmidt-Cassegrain designs, a table with specifications for visual and imaging, graphics showing how to place sensors at the optimum back-focus distance, and details on the construction and testing of the EdgeHD telescope series.

Diffraction Limited
Some companies boast that their telescopes give diffraction limited stars in the very center of the field of view. EdgeHD optics not only produce diffraction limited stars on axis, but maintain diffraction limited stars across the entire field of view of many of the most popular astrophotography cameras. Even at the very edge of a full frame camera chip, the EdgeHD 14" delivers star sizes of only 1 arc second!
Along with the newly designed optics, the EdgeHD also has re-designed mechanics guaranteed to help you get the maximum performance from your instrument.
Features Include:
Mirror Locks – To hold the mirror in place and reduce image shift during imaging.
Tube Vents - Each vent has an integrated 60 micron micro-mesh filter allowing hot air to be released from behind the primary mirror.
Fastar Versatility – All EdgeHD optical tubes are equipped with a removable secondary mirror for fast f/2 CCD imaging. Not only does imaging in the FASTAR configuration allow for exposure times that are 25 times faster than at f/10, but also yields a field of view five times wider. The perfect combination for imaging your favorite wide field objects in a fraction of the time. (FASTAR imaging requires a third party lens assembly in place of the secondary mirror).
82° Eyepiece - EdgeHD 14" optical tubes come with Celestron's top of the line 2" barrel eyepiece. With a 23 mm focal length and 82° AFOV, you get an incredible combination of power and wide field of view. Plus this 6-element eyepiece is optimized to deliver pinpoint images when used with a flat field telescope.

The EdgeHD 14" optics produce a focal plane three-times flatter than the standard equivalent SCT telescope with diffraction limited stars to the very edge of the SBIG STL6303 field of view!
