Engineered to deliver sharp and clear distortion-free views, the Celestron EdgeHD 11" f/10 Aplanatic Schmidt-Cassegrain Telescope is an ideal choice for observation, astrophotography, and imaging objects within or beyond our solar system. 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 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 122x power. A reducer adapter is provided to allow the use of smaller and more common 1.25" eyepieces and accessories. The EdgeHD 11 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.

Celestron EdgeHD 11" f/10 Aplanatic Schmidt-Cassegrain Telescope (OTA Only)

Optical Tube

11" (280mm) aperture
f/10 focal ratio
2800mm 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: 0.5 arcsec (Rayleigh); 0.42 arcsec (Dawes)
Secondary mirror obstruction: 3.75" (95 mm); 34% by diameter; 12% 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 122x 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

Celestron CGX-L GoTo EQ Telescope Mount Head

The Celestron CGX-L GoTo EQ Telescope Mount Head improves on the 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 heavy 75-pound 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 brain of the CGX-L is the 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 to 200 custom user-defined objects with filters added to 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.

Celestron offers this version of the CGX-L mount without a tripod for users who already have a tripod or pier. The Vixen/Losmandy dual dovetail saddle has also been lengthened to 10.6" to improve stability and offer greater security for larger OTAs.
