Celestron Advanced VX 11" Schmidt-Cassegrain Telescope

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 has a Vixen-style saddle to match the OTA's CG-5 mounting plate.

Engineered and optimized for astrophotography with mid-sized optical tube assemblies, the Celestron Advanced VX GoTo German Equatorial Mount delivers the performance required for clear images through the use of dual-axis low-cog DC servo motors and backlash compensation. Added to this are encoders on the motors and Permanent Periodic Error Correction (PPEC) which help to improve positioning and tracking precision and ensure your target object stays centered for long-exposure photography techniques. Supporting the mount is a large 2" stainless steel tripod that has a wide stance for stability on most terrain, and a center tray that holds 1.25" and 2" eyepieces and accessories and acts as a leg-lock to further stabilize while helping to minimize vibrations.

The brain of the system is the NexStar+ computer controller which is equipped with a database of over 40,000 objects, including the planets, stars, nebulae, galaxies, and the complete Messier catalog; it can also be programmed with up 100 custom user-defined objects with filters to create custom object lists. Its intuitive menu-driven user interface makes observing the heavens fast and easy; features such as guided tours, extended information on 200 popular objects, and multiple alignment options make the NexStar+ controller an invaluable tool to new users and experienced star-gazers alike.
