Product Highlights

  • 9.25" Schmidt-Cassegrain OTA
  • 2350mm focal length, f/10 Focal Ratio
  • StarBright XLT Optical Coatings
  • 25mm Eyepiece, 90° Diagonal
  • 6x30 Finderscope
  • CGE (Losmandy) Dovetail Plate
  • OTA Only; Mount and Tripod Required

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 the user's 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 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
  • Broad-band 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 that is compatible with Losmandy-style saddles
  • Mount must have a payload capacity of over 20 pounds to safely support the OTA
