Astrozap For Celestron 11" SCT, Texture Black Finish Aluminum

AstroZap Aluminum Dew Shield for Celestron 11" SCT – Textured Black Finish

The Celestron 11" SCT strikes a perfect balance between portability and power—but like all Schmidt-Cassegrains, it has one Achilles’ heel: dew. The AstroZap Aluminum Dew Shield offers observatory-grade protection for your optics with the added durability and polish of a textured black powder-coated finish that looks as good as it performs.

Made from lightweight yet rigid aluminum, this shield won’t warp, sag, or lose shape over time like plastic alternatives. The interior is lined with light-absorbing black felt, which helps prevent dew formation by reducing radiative heat loss and cuts down on stray light from street lamps, moonlight, and other ambient sources.

Designed specifically for the Celestron 11" SCT optical tube, this shield provides a secure fit and includes a Velcro-backed fastening system for tool-free installation. It’s a rock-solid upgrade whether your setup is mobile or permanently mounted in a roll-off or dome observatory.

Features:

• Custom fit for Celestron 11" Schmidt-Cassegrain Telescopes

• Constructed from rigid aluminum with a textured black powder-coated finish

• Felt-lined interior reduces dew and improves contrast

• Velcro fastening strip for quick, secure, and tool-free installation

• Won’t sag, flex, or warp—ideal for long-term or observatory use

• Blocks stray light and preserves corrector plate clarity during extended sessions

Observing Tip:

If you frequently set up at outreach events or leave your scope in a semi-permanent observatory, the rigid construction of an aluminum dew shield offers both performance and peace of mind. It adds just the right amount of thermal and mechanical protection—without sacrificing style.
