Astrozap Dew Shield for Celestron 11" SCT, Flexible Black Plastic

AstroZap Flexible Dew Shield for Celestron 11" SCT – Black Plastic

The Celestron 11" Schmidt-Cassegrain is a true staple in amateur astronomy—big enough for serious planetary and deep-sky work, yet portable enough to travel. But that wide corrector plate is also a magnet for dew and glare. The AstroZap Flexible Dew Shield gives your C11 a lightweight, field-friendly layer of protection, helping you stay clear and contrast-rich throughout your observing session.

Made from rugged, lightweight black plastic, this dew shield wraps around the front cell of your OTA and fastens securely with a Velcro strip. Inside, a felt-lined interior acts as a barrier against radiative cooling while absorbing ambient light—greatly reducing dew buildup and improving visual and imaging contrast under light-polluted skies.

Tailored for the Celestron 11" SCT, this model provides a snug fit with no interference from mounting rails or accessories, and rolls up compactly when not in use. Whether you’re imaging, viewing, or doing both, this shield is a must-have for maintaining optimal performance in the field.

Features:

• Designed for Celestron 11" Schmidt-Cassegrain Telescopes

• Constructed from flexible black plastic for lightweight durability

• Felt-lined interior helps block stray light and reduce dew formation

• Velcro closure for quick, tool-free setup and removal

• Rolls up easily for storage and travel

• Improves optical contrast and keeps your corrector plate dry longer

Observing Tip:

Even if dew isn't an immediate concern, the light-blocking benefit of a dew shield can significantly enhance your views—especially in suburban or semi-lit environments. It’s a small upgrade that makes a big difference.
