A superior choice for astronomy enthusiasts the C6-A 6 Schmidt-Cassegrain Optical Tube Assembly is designed to seamlessly fit CG-5 Mounts. This high-quality durable optical tube assembly is a part of Celestron s innovative range of telescopes renowned for their advanced technology and sturdy construction. The C6-A features the multicoated Starbright XLT Coatings a unique feature that sets it apart from ordinary 8 optical tube assemblies. These highly reflective coatings are meticulously applied on the mirrors while anti-reflective coatings are employed on the correcting lens. This strategic use of coatings significantly enhances light transmission allowing for a brighter and clearer image of celestial objects. Celestron s optical systems are designed with internal baffling to ensure the highest contrast levels providing you with an unparalleled viewing experience. This advanced design element contributes to the C6-A s ability to bring the faintest objects your scope can resolve into greater detail. Regardless of their size or configuration all Celestron Schmidt-Cassegrain optical assemblies utilize the same superior optics maintaining the company s commitment to consistently high performance and customer satisfaction. The StarBright XLT coatings dramatically decrease the total percentage of light loss incurred by the scope s system of lenses & mirrors by a measure of 43%. This reduction in light loss can have a particularly dramatic effect on the visibility of deep space objects. The C6-A 6 Schmidt-Cassegrain Optical Tube Assembly is not just an addition to your astronomy equipment but a gateway to exploring the wonders of the night sky with enhanced clarity and detail.
