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.
The EdgeHD 14 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 mirror support knobs 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 and prevent 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
Visual Back:
- Standard Schmidt-Cassegrain telescope (SCT) threads
- 2" eyepiece/accessory holder
- Use for prime focus or projection astrophotography with optional adapters
Eyepiece:
- Luminos-series wide-angle
- 82° field of view
- 2"-diameter barrel
- Accepts most 2" eyepiece filters
- 23mm focal length yields 170x power
- 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
Diagonal:
- 90° angle puts head in comfortable viewing position
- 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:
- Low 9x magnification preserves wide field of view to more easily find alignment or guide stars
- Large 50mm aperture helps to see dimmer objects and stars for easier star-hopping navigation
