Celestron Dew Shield DX – Deluxe Flexible Dew Shield for 9.25" and 11" OTAs
Protect Your Views from Dew and Stray Light—With a Fit Designed Just for Celestron
If you’ve ever watched your crisp, contrast-rich views disappear behind a foggy corrector plate, you already know: dew is the enemy of the observing session. The Celestron Dew Shield DX is your first line of defense. Designed specifically for 9.25" and 11" Schmidt-Cassegrain, EdgeHD, and RASA OTAs with single dovetails, this flexible, durable shield helps keep your optics dry, your images sharp, and your session going.
Designed for a Perfect Fit
Unlike generic dew shields, the Dew Shield DX is purpose-built for Celestron optical tubes. It wraps snugly around the OTA and fastens securely with adjustable Velcro tabs, ensuring a firm grip even in breezy conditions. A precision-cut dovetail notch accommodates both standard and extra-wide (up to 4") dovetail rails, offering a rock-solid fit that won’t torque, twist, or shift during the night.
Dual Defense: Dew Control + Stray Light Suppression
The Dew Shield DX protects your corrector lens in two important ways:
-
The extended front baffle physically reduces the sky-facing area exposed to radiative cooling, helping prevent dew from condensing on your optics.
-
The felt-lined interior absorbs stray light and ambient reflections, boosting image contrast—especially important for astrophotographers or urban observers battling local light pollution.
Whether you're chasing Jupiter through gaps in the clouds or capturing long exposures of faint galaxies, the Dew Shield DX gives your telescope the stable thermal and optical environment it needs to perform its best.
Built to Travel
Constructed from tough yet flexible polyethylene (PE) plastic, the Dew Shield DX is built to survive years of star parties and road trips. Despite its generous 42" length, it rolls up easily to fit in your accessory bag, and its lightweight design (just 1.8 lbs) won’t throw off your mount’s balance.
Observing Tip:
Pair your dew shield with a dew heater strap and controller for maximum protection during long imaging sessions or high-humidity nights. The dew shield slows down moisture accumulation while the heater keeps your optics just above ambient temperature—a winning combo for clear views all night long.
Final Thoughts
Dew is sneaky, silent, and session-ending—unless you’re ready for it. The Celestron Dew Shield DX gives your telescope an easy, affordable, and travel-friendly upgrade that makes a big difference in real-world observing. Whether you're imaging the Veil Nebula or enjoying a crisp view of Saturn’s rings, this shield helps your optics stay clear and your contrast stay high.
