Celestron C6-A-XLT CG-5 6" f/10 Schmidt-Cassegrain Telescope (OTA Only)
Key Features
  • 6" (150mm) Schmidt-Cassegrain OTA
  • 1500mm Focal Length, f/10 Focal Ratio
  • StarBright XLT Optical Coating System
  • 25mm Eyepiece and 90° Star Diagonal
Striking a comfortable balance between power and portability, the Celestron C6-A-XLT CG-5 6" f/10 Schmidt-Cassegrain Telescope is an ideal choice for observing objects within or beyond our solar system. It features a Schmidt-Cassegrain optical system consisting of a corrector plate, spherical primary mirror, and secondary mirror that work together to reduce spherical and chromatic aberrations for crisp and clear high-resolution images with accurate color representation without distortion, especially at the edges. Complementing the optical system is the proprietary StarBright XLT optical coating system, which improves light transmission and reflectivity across the entire visual spectrum.

Striking a comfortable balance between power and portability, the Celestron C6-A-XLT CG-5 6" f/10 Schmidt-Cassegrain Telescope is an ideal choice for observing objects within or beyond our solar system. It features a Schmidt-Cassegrain optical system consisting of a corrector plate, spherical primary mirror, and secondary mirror that work together to reduce spherical and chromatic aberrations for crisp and clear high-resolution images with accurate color representation without distortion, especially at the edges. Complementing the optical system is the proprietary StarBright XLT optical coating system, which improves light transmission and reflectivity across the entire visual spectrum.

The optical tube is outfitted with a standard 1.25" visual back to make it easier to find eyepieces, accessories, and imaging gear. For visual observations, a 1.25" star diagonal is included along with a 25mm eyepiece that yields 60x magnification. The C6-A-XLT 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 comes with a standard-sized CG-5 dovetail plate that is compatible with Vixen-style saddles.

Optical Tube

  • 6" (150mm) aperture
  • f/10 focal ratio
  • 1500mm effective focal length
  • Schmidt-Cassegrain catadioptric optical design
  • StarBright XLT optical coatings
  • Resolution: 0.93 arcsec (Rayleigh); 0.77 arcsec (Dawes)
  • Secondary mirror obstruction: 2.2" (69mm); 37% by diameter; 14% 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

  • Optical tube assembly (OTA) only, mount and tripod required for proper use
  • Standard CG-5 (Vixen-style) dovetail plate for compatible saddles
  • OTA weight: 10 pounds

Included Accessories

  • Visual back:
  • Standard Schmidt-Cassegrain telescope threads
  • 1.25" eyepiece/accessory holder
  • Use for prime focus or projection astrophotography with optional adapters
  • Eyepiece:
  • 1.25"-diameter barrel
  • Accepts most 1.25" eyepiece filters
  • 25mm focal length yields 60x power
  • 0.83° apparent angle of view
  • 44' field of view at 1000 yards
  • Diagonal:
  • 90° angle puts head in comfortable viewing position
  • Threaded for direct connection to OTA without the need for the visual back
  • 1.25" snout and eyepiece/accessory holder
  • Star diagonal corrects image horizontally, but not vertically
  • Finderscope:
  • Low 6x magnification preserves wide field of view to more easily find alignment or guide stars
  • 30mm aperture helps to see dimmer objects and stars for easier alignment and star-hopping navigation

Is the dovetail compatible with an Orion Starseeker IV mount?
Asked by: Ken
The Celestron C6-A-XLT CG-5 6" f/10 Schmidt-Cassegrain Telescope has a standard Vixen dovetail rail so it will fit any brand mount that uses a Vixen dovetail. We do not sell Orion brand mounts but based on the specs on Orion's website, the Celestron telescope not will fit. Plus the Orion mount only supports 13 pounds. The Celestron scope weighs 10. I would recommend using a stronger mount for the Celestron such at this scope and mount kit: https://bhpho.to/2YyNBqG
