Product Description

Celestron CGX-L Equatorial 14" EdgeHD Telescope

CELESTRON • EdgeHD 14" Optical Tube Assembly (OTA)

This 14" EdgeHD is an aplanatic, flat field Schmidt-Cassegrain telescope that produces aberration-free images across a wide visual and photographic field of view. The optical system was designed to reduce more than just off-axis star coma; it also provides an astrograph-quality flat focal plane all the way to the edge of the field of view. The EdgeHD optics consist of a zero power corrector plate, a spherical primary mirror, and a secondary mirror along with a set of field flattening lenses which reside in the baffle tube. The optics of an EdgeHD telescope feature StarBright XLT multi-layer coatings on the primary and secondary mirrors for increased reflectivity. The corrector is also multi-layer coated to ensure enhanced anti-reflection characteristics.

TRUE ASTROGRAPH QUALITY
Many optical designs that advertise themselves as "astrographs" actually only produce pinpoint stars across a curved focal plane. While this may be acceptable for some visual observing, stars will appear out of focus at the edge when used with the flat chip sensor of a digital camera. EdgeHD optics produce a focal plane more than three-times flatter than a standard Schmidt-Cassegrain telescope and dramatically flatter than competing coma-free designs. This guarantees you visibly sharp stars across some of the largest CCD chips available today.

IMPROVED PERFORMANCE
Superior edge performance not only creates rounder, more pleasing stars, but actually improves the resolution and limiting magnitude when compared to telescopes of equal aperture. With Celestron’s StarBright XLT Multi-Layer optical coatings on every surface, EdgeHD optics gives you maximum light throughput across the widest visual and photographic spectrum.

MECHANICAL FEATURES
In addition to EdgeHD’s optimized optical design, the telescope tube has been redesigned to make sure you get the most from your optics each and every night. Normal image orientation for the EdgeHD design is upside-down and reversed. The 2.0" diagonal inverts this image so it is right-side-up, but reversed. This diagonal directly accepts 2.0" eyepieces, and a 1.25" eyepiece adapter is included.
MIRROR CLUTCHES - Flexible tension clutches hold the mirror in place and reduce image shift when taking long exposure astro-images. Once focused, the flexible rods allow the mirror to be held in place without putting any force or pressure on the mirror assembly, keeping the image centered in the eyepiece (or on the sensor).
TUBE VENTS - Cooling vents located on the rear cell allow hot air to be released from behind the primary mirror. Each vent has an integrated 95-micron micromesh filter guaranteed to let warm air out without letting dust in.
FASTAR VERSATILITY - EdgeHD is the most versatile imaging telescope available today. At its native f/10, you can achieve the image scale necessary to capture the smallest of deep sky objects. Add the optional reducer lens—custom-designed for your size EdgeHD tube—and you can increase your field of view without sacrificing optical performance. A Barlow gives you added power for high-resolution planetary, lunar and solar imaging. All EdgeHD optical tubes are Fastar-compatible, allowing the secondary mirror to be removed and replaced with a third party lens accessory for ultra-fast f/2 wide field imaging.

INDIVIDUALLY TESTED
Every EdgeHD that ships has been tested not only for the surface quality of each optical component, but also with a camera and artificial star to ensure the imaging system meets Celestron's rigid performance quality. This “final acceptance test” confirms the EdgeHD will perform in the field and deliver high-quality astroimages.

 Standout Features:

  • A step up from traditional Schmidt-Cassegrains
  • EdgeHD creates pinpoint stars throughout the entire field of view
  • 2580x light gathering power compared to the naked eye
  • Normal focal ratio of f/11
  • Fastar focal ratio of f/2
  • StarBright XLT coatings for improved light transmission
  • Includes a 23mm 82° 6 element Axiom LX eyepiece
  • Also Includes a Wide Field 9x50 Finderscope
  • Plus a 90° Diagonal w/ StarBright XLT coatings

Celestron CGX-L Equatorial Mount

Part of the next generation of equatorial mounts from Celestron, the CGX-L features a robust load capacity of 75 pounds with an excellent load to weight ratio.  Designed with imaging in mind, you will find additional auxiliary ports and an autoguiding port on the dec for improved cable management.   Worm gears have been upgraded to a larger (compared to previous models) 144mm gear for excellent tracking and slewing with heavy loads and smart design improvements like a longer saddle plate and 2.75" provide a highly stable and secure platform for your large aperture telescope.  

With a shorter, more compact mount head and built in handles, the CGX-L is surprisingly easy to carry and assemble.  As part of it's ergonomic design, the adjustment knobs are designed for reduced friction and a stationary latitude knob with a newly-designed linkage system greatly reduces the amount of friction when polar aligning the mount. Teflon bearings on the azimuth adjustment allow you to adjust even with a full load on the mount and an the latitude scale is large, clear and easy to read. 

CGX-L Features:

  • 75 pound load capacity
  • A shortened mount profile creates a more compact mount that is easier to carry and assemble but also improves the mounts central gravity boosting load capacity.
  • High torque motors with better slewing and tracking ability.
  • A belt driven motor minimizes backlash but remains smooth even when handling a large telescope.  A clear window allows you to easily monitor the motor.  
  • Spring loaded brass worm wheel and stainless steel worm gear.  By spring loading the motor worm and gear, gear friction is greatly reduced and optimal gear mesh is maintained. 
  • Internal cabling keeps your mount free from cable clutter and reduces the chance of snagging wiring.  The power input port and accessory ports stay in one position at all times.  
  • The CGX-L has built-in physical hard stops and optical hard stops eliminating the chance that the counterweight shaft will strike the leg.   
  • Designed for easy remote control, home sensors allow you to start in the index position no matter what position the mount was in when it was powered off. 
  • Includes a USB 2.0 Nexstar+ hand controller equipped with Celestron's PWI telescope control software designed in partnership with PlaneWave Instruments, featuring multi-point mount modeling for precision pointing accuracy. 
  • Includes Celestron's All Star Polar Alignment for incredibly accurate guided polar alignment allowing you to align with any bright fixed object in the night sky.  There's no need for additional polar finders or accessories.  
  • The head of the Celestron CGX-L is fully adjustable allowing you to slide the telescope perfectly over the center of gravity and take full advantage of the 3º-65º latitude range.
  • Includes a dual saddle plate to accommodate both D and V series dovetail plates. 
  • +20º of additional tracking past the meridian on either side
  • The 2.75" steel tripod has been newly designed for the CGX-L with a wider stance and a lower minimum height than it's predecessors.  
  • 2 autoguider ports for better cable management.  
  • PEC sensor and PPEC ready. 
  • A threaded power connector to ensure your mount never comes disconnected at the base. 
  • A red lit on/ off switch makes it easy to find in the dark. 
  • Internal Real Time Clock.
