Celestron Deluxe Flexible Dew Shield DX for 6" and 8" Optical Tubes (#94018)
Protect your corrector plate, boost contrast, and fight dew the easy way.
If you’ve spent time under the stars with a Schmidt-Cassegrain, EdgeHD, or RASA optical tube, you know the heartbreak of watching your corrector plate fog over just as Saturn rises or your camera hits peak focus. The Celestron Dew Shield DX offers a simple and effective solution—blocking both dew and stray light before they can compromise your night’s observations.
Specifically designed for Celestron 6" and 8" SCT, EdgeHD, and RASA OTAs, this premium flexible dew shield helps ensure your corrector lens stays clear, while its felt-lined interior enhances image contrast by absorbing ambient light.
Thoughtfully Engineered for a Custom Fit
Unlike generic wraparounds, the Dew Shield DX is tailored for Celestron tubes. It includes a precision-cut notch to accommodate wide dovetail rails—up to 4"—and forms a snug fit at the front end of your scope with Velcro-secured overlap. Whether you're mounting your OTA in alt-az or equatorial mode, the dew shield sits flush without interfering with hardware or balance.
The interior surface is lined with high-quality felt, which not only cuts down on stray light but also acts as a trap for moisture particles—giving you a double layer of dew protection. Celestron has even added reinforced padding at the tube edge for a more secure grip during long sessions.
Flexible, Durable, and Portable
Constructed from tough but lightweight polyethylene (PE), the Dew Shield DX holds its shape in the field but rolls up easily for transport and storage. It’s a rugged and road-ready solution that’s just as happy on a backyard Dob as it is under the dark skies of a star party.
Final Thoughts
If you observe or image in climates where humidity or dew are common—and let’s face it, that’s most of us—the Celestron Dew Shield DX is one of the simplest ways to protect your investment and your view. Add it to your SCT or EdgeHD setup and spend more time observing and less time wiping lenses.
