Celestron C11 SC

1. Advanced Optical Design: The Celestron C11 SC is a Schmidt-Cassegrain (SCT) telescope, a catadioptric design that merges mirrors and a corrector plate to produce a remarkably compact optical tube with a long focal length. This closed-tube system minimizes internal air currents and dust intrusion, reducing maintenance needs and providing excellent image stability. It is intended for serious amateur astronomers and astrophotographers seeking high performance across various observing fields.

2. Superior Light Gathering: With a substantial 11-inch (279.4 mm) aperture, the C11 SC excels at gathering vast amounts of light, making it ideal for observing faint deep-sky objects like nebulae and galaxies, as well as providing incredibly detailed views of the Moon and planets. Its large primary mirror effectively captures more photons, translating into brighter and clearer images.

3. StarBright XLT Coatings: Each optical surface is meticulously coated with Celestron's proprietary StarBright XLT coatings. This multi-layer system dramatically increases light transmission across the visual spectrum, ensuring maximum image brightness and contrast. The result is consistently sharp, high-fidelity views with accurate color reproduction, crucial for both visual astronomy and demanding astrophotography.

4. Versatile f/10 Focal Ratio: The C11 SC features a 2800mm focal length, equating to a versatile f/10 focal ratio. This makes the telescope well-suited for a wide range of applications, from high-magnification planetary observation to capturing detailed astrophotographs of smaller celestial targets. Its optical precision and adaptable focal length offer exceptional performance for both visual and imaging pursuits.

ABOUT THE CELESTRON C11 SC

The Celestron C11 SC stands out as a highly versatile and powerful Schmidt-Cassegrain (SCT) telescope, designed to deliver exceptional performance for both astrophotography and advanced visual observation. As a catadioptric instrument, it ingeniously combines mirrors and lenses to fold a long focal length into a remarkably compact and portable tube. This design minimizes aberrations while maintaining a wide field of view, making it unique among its peers. Its 11-inch aperture provides immense light-gathering power, revealing faint nebulae and distant galaxies with stunning clarity, while also offering razor-sharp, high-contrast views of the Moon and planets when observing from terrestrial locations or during special celestial events. Constructed with a robust aluminum tube and featuring premium optics enhanced with StarBright XLT coatings, the C11 SC ensures maximum light transmission and superior image brightness. While primarily intended for deeper space exploration and detailed planetary studies, its compact form factor also makes it suitable for advanced amateur astronomers with limited storage or transportation options. The mirror support system further enhances its stability for critical astrophotography by minimizing mirror shift.
