Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope (OTA Only, CGE Dovetail)

Outfitted with a large aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C9 1/4-A XLT 9.25" f/10 Schmidt-Cassegrain Telescope provides 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 1.25" visual back to accept eyepieces and accessories such as the 25mm eyepiece and 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 20 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

  • 9.25" (235mm) aperture
  • f/10 focal ratio
  • 2350mm effective focal length
  • Schmidt-Cassegrain design optical path
  • StarBright XLT optical coatings
  • Resolution: 0.59 arcsec (Rayleigh); 0.49 arcsec (Dawes)
  • Secondary mirror obstruction: 3.35" (85 mm); 36% by diameter; 13% 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 20 pounds to safely support the OTA

Included Accessories

  • Visual back:
  • Standard threads for Schmidt-Cassegrain telescope optical tubes
  • 1.25" eyepiece holder accepts 1.25" eyepieces and accessories
  • Eyepiece:
  • 1.25"-diameter barrel
  • Accepts most 1.25" astronomical filters
  • 25mm focal length produces 94x magnification
  • Diagonal:
  • 1.25"-diameter barrel
  • 90° angle places head in comfortable viewing position when scope is aimed at or near the zenith
  • Star diagonal corrects view horizontally, but not vertically
  • Finderscope:
  • 6x magnification
  • 30mm aperture
  • Mounting bracket included
