Celestron C11-A XLT 11" f/10 Schmidt-Cassegrain Telescope (OTA Only, CGE Dovetail)
Key Features
  • 11" Schmidt-Cassegrain OTA
  • 2800mm Focal Length, f/10 Focal Ratio
  • StarBright XLT Optical Coatings
  • 40mm Eyepiece, 90° Diagonal
Outfitted with an over-sized aperture, long effective focal length, and their proprietary StarBright XLT optical coatings, the Celestron C11-A XLT 11" 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 40mm 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 27.5 pounds to safely carry the weight and that the mount has a Losmandy-style saddle to match the OTA's CGE mounting plate.

Can you see planets close up with this telescope ...

Can you see planets close up with this telescope or are they far away?
Asked by: Valeria
The C11 optical tube will show surface features of Mars during favorable oppositions, Jupiter's cloud bands and it's Great Red Spot. Saturn's Cassini ring division is easily viewable. Mercury is too small and too close the sun to see much detail. Venus is covered in clouds, so it appears featureless, but you can observe its phases. Uranus and Neptune are too far away and will resemble bluish dots.

Can I attach a DSLR to this for astrophotographery?
Asked by: Juan
Yes, you can. You will need the Celestron T-Adapter for SCT telescopes #93633-A, which attaches an SLR or DSLR camera to a Schmidt-Cassegrain telescope for prime focus photography. You will also need a camera specific T-Ring (Canon or Nikon). Inquire with B&H for availability. An optional Focal Reducer #94175 is also available if you so choose.
