Your cart is empty. The Celestron Dew Shield DX is an essential accessory that protects your optical tube in the field. It prevents excess moisture in the air from forming condensation on the corrector lens. A dew shield also helps block stray light from entering the telescope for better viewing and astroimaging. Use the Dew Shield DX on your 9.25” and 11” Schmidt Cassegrain, EdgeHD, and RASA (with single dovetail) optical tubes with confidence.
Construction
The Dew Shield DX provides a perfect, custom fit designed specifically for 9.25” and 11” Celestron optical tubes. The Dew Shield is built from durable PE plastic that is flexible but strong. Extra padding has been added at the tube attachment edge to create a stronger fit on the optical tube. The felt-lined interior absorbs any additional stray light and excessive moisture, creating optimal contrast when viewing and imaging. The large dovetail cutout has been made both wider- to accommodate a 4” wide dovetail rails, as well as deeper, to create a more solid connection with the optical tube.
Attaching the Dew Shield to your optical tube is easy thanks to the Velcro attachment points. Whether your optical tube is 9.25” and 11”, simply adjust the Velcro for the correct fit.
Transportation and Storage
To save space when not in use, roll up your Dew Shield DX for easy transport and storage.

If you're worried about dew, why mess around with this? Just get a dew heater. If you need some better darkness, so to speak, around the aperture (e.g., for photography), it helps. But if you have any significant dew and you're worried about condensation on your lens, go with the heated route (Astrozap strip, or a ring from Celestron, using the Astrozap controller). Came packaged flat out, very large box (but thin), seems like a huge waste of cardboard when it could have been rolled up, which it's going to be anyway when storing or transporting it at home.

I purchased this for a Celestron 11" SCT. It is very high quality and has the added flexibility to fit the smaller 9.25" optical tube as well. The Velcro fastener is very good compared to some other shields. The fit and finish are outstanding. Highly recommended and a great price!

If you have street lights or other lighting in the area this is a must to reduce the light pollution on the image.

Maybe it’s just mine since it has a ripple crease in it, but I can’t seem to get it to maintain a circular shape when on the OTA so it partially blocks the corrector plate. I’ll be sending back and either getting a direct replacement (others don’t seem to report this issue) or looking for a metal dew shield.

Although this product doesn't completely diminish the formation of dew on the front glass of my SCT scope it does slow down the process quite a lot. I can usually get 2-3 hours without any dew formation on my telescope when the dew point is high. Worth buying if you have a 9.25 to 11inch SCT telescope.

If you have a C series scope, dew is a concern. The concern increases along with the size of the glass. Celestron has 2 options. The least expensive option is the hood that attaches via velcro and is made of plastic and vinyl. The other choice is a metal hood and has built in ports to accommodate Celetron's powered dew heater (sold separately). Both are good choices, They both work well, the deciding factor is of course always price vs convenience vs budget.If you travel with your Scope, the basic hood can be folded flat when removed and is lighter. The Metal hood can be removed but takes up more space and is heavier if that matters. I have both. when I am home the metal version stays on my C9. if I travel to site, it stays at home.

This inexpensive Dew Shield from Celestron is extremely well-made. Not only is the it durable, but it’s thick and weather resistant. I use it on every session with my 11†Celestron SCT. The cut-out fits perfectly around the bottom dovetail and the heavy-duty Velcro keeps a nice tight fit. Highly recommended if you can’t afford Celestron’s aluminum Dew Shield.

Been having some significant issues with dew each summer, this product completely kept my 9.25 Dee free the entire viewing time as compared to completely covered in dew without it. Works fantastic!

It could use additional velcro materials to attach directly on the telescope tube and the interior of the Dew Shield
