Product description

• EdgeHD 14" f/11 Aplanatic Schmidt-Cassegrain Telescope (OTA Only)
  • CGX-L German Equatorial Mount - Product Tour
  Engineered to deliver sharp and clear distortion-free views, the Celestron EdgeHD 14" f/11 Aplanatic Schmidt-Cassegrain Telescope represents the largest aperture in the EdgeHD series and is an ideal choice for observation, astrophotography, and imaging objects beyond our solar system with exceptional sharpness and resolution, as well as magnification potential. It features an aplanatic Schmidt-Cassegrain optical system consisting of a corrector plate, a spherical primary mirror, and a secondary mirror along with a set of field-flattening lenses integrated into the baffle tube. Complementing the EdgeHD system is the proprietary StarBright XLT optical coating system, which improves light transmission and reflectivity across the entire visual spectrum. The combination of EdgeHD and StarBright XLT produces bright and clear high-resolution images with true color rendition across the entire field of view without distortion, aberrations, or off-axis comas.Optimized for imaging, the internal focusing system features a mirror support clutches to ensure proper alignment and mirror locks to avoid accidental defocusing during long-exposure astrophotography. The optical tube is outfitted with an oversized 2" visual back to ensure large imaging sensors are completely covered to avoid vignetting. For visual observations, a 2" star diagonal is included along with a 23mm wide-angle eyepiece that yields a respectable 170x power. A reducer adapter is provided to allow the use of smaller and more common 1.25" eyepieces and accessories. The EdgeHD 14 is offered here without a mount or tripod for users who already have a reliable support system and are looking to upgrade or add to their existing gear, but it comes with a large CGE dovetail plate that is compatible with Losmandy saddles.
  Optical Tube
  • • 14" (356mm) aperture
    • f/11 focal ratio
    • 3910mm effective focal length
    • Aplanatic Schmidt-Cassegrain optical design
    • EdgeHD field-flattener aplanatic design eliminates spherical aberration, field curvature, and off-axis star coma to improve resolution, sharpness, and clarity across the entire field of view, especially at the edges
    • Diffraction-limited SCHOTT glass reduces internal light loss to improve color, clarity, and sharpness
    • StarBright XLT optical coatings
    • Flexible tension clutches hold the primary mirror in place to reduce image shift without putting any force or pressure on the mirror assembly, keeping subjects centered
    • Internal mirror locks prevent accidental adjustment to focus—important during long-exposure astrophotography
    • Integrated 95-micron mesh filter allows hot air to be released from behind the primary mirror without dust getting in, to prevent mirror distortion due to uneven surface temperatures
    • Resolution: 0.39 arcsec (Rayleigh); 0.33 arcsec (Dawes)
    • Secondary mirror obstruction: 4.5" (114 mm); 32% by diameter; 10% by area
  StarBright XLT System
  • • Maximizes light transmission through optical path
    • Improves color rendition, contrast, sharpness, resolution, and brightness
    • Broadband system provides flat wavelength transmission across the entire visual spectrum
    • Multi-layer mirror coatings with layers of aluminum, SiO2 (quartz), and TiO2 (titanium dioxide)
    • Multi-layer anti-reflective corrector plate coatings with layers of MgF2 (magnesium fluoride) and HfO2 (hafnium dioxide); hafnium has a wider band-pass than the commonly used titanium
    • High-transmission water white glass corrector plate limits light loss due to internal absorption
  Mounting
  • • OTA only; mount and tripod required for proper use
    • Large CGE (Losmandy-style) dovetail plate
  Included Accessories

    • Parfocal with all Luminos eyepieces, allowing it to be changed out with other Luminos eyepieces without having to adjust the focus
    • Retractable eyecup for use with or without eyewear
    Reducer adapter:
    • 2"-to-1.25" reducer adapter allows the use of smaller eyepieces and accessories in visual back or diagonal

    • Threaded for direct connection to OTA without the need for the visual back
    • 2" eyepiece/accessory holder
    • Star diagonal corrects image horizontally, but not vertically
    Finderscope:

• CGX-L GoTo EQ Mount with Tripod With an upgraded payload capacity, tripod, and internal gears, the Celestron CGX-L GoTo EQ Mount improves on their venerable CGX platform to provide users with a heavy-duty research-quality mount for larger optical tube assemblies (OTAs), accessories, and imaging rigs. Engineered to carry a 75 lb payload, and outfitted with high-torque motors and a heavy-duty belt-drive system to improve tracking stability and reduce backlash, it is able to smoothly and accurately track near- and deep-sky objects for extended periods of time.The Vixen/Losmandy dual dovetail saddle has also been lengthened to 10.6" to improve stability and offer greater security for larger OTAs. To provide a solid platform for the mount and your OTA, a heavy-duty stainless steel tripod is included, sporting massive 2.75"-diameter legs, an accessory tray that doubles as a stabilizer, and an adjustment range from 35.75" to 52.75". The minimum height has been lowered almost a foot versus the earlier CGX model to accommodate a wider range of users and different observation positions.The brain of the CGX-L is the venerable NexStar+ computer controller. Equipped with a database of 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog, it can also be programmed with up 200 custom user-defined objects with filters added for custom object lists. Its intuitive menu-driven user interface gives you the power to observe the heavens with nine slew speeds, three tracking rates, anti-backlash compensation, and Permanent Periodic Error Correction (PPEC) for smoother movements in the motors and improved tracking over time. Features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller easy to use and invaluable to both new users and experienced stargazers.
