Outfitted with an oversized aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C14-AF XLT 14" f/11 Schmidt-Cassegrain Telescope provides high power and portability. The coating system consists of anti-reflection coatings on the corrector plate, highly reflective index mirror coatings, and low-absorption/high-transmission glass components to ensure that the maximum amount of light is gathered and transmitted to your eye. This system ensures bright and clear high-contrast images with accurate color rendition across the entire visual spectrum without visible distortion at the edges. Celestron includes a standard-thread 2" visual back and reducer adapter to accept eyepieces and accessories such as the 1.25" 40mm eyepiece and 2" 90° diagonal supplied with the optical tube assembly (OTA). This OTA is offered here without a mount or tripod for users who already have a support system. Just ensure the mount's payload capacity exceeds 45 pounds to safely carry the weight and that the mount has a Losmandy-style saddle to match the OTA's CGE mounting plate.

Optical Tube

  • 14" (355.6mm) aperture
  • f/11 focal ratio
  • 3910mm effective focal length
  • Schmidt-Cassegrain design optical path
  • StarBright XLT optical coatings
  • 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

  • Optical tube only—mount and tripod required for proper use
  • Supplied with CGE dovetail plate, which is compatible with Losmandy-style saddles
  • Mount must have a payload capacity of over 45 pounds to safely support the OTA
