Construction
The Dew Shield DX provides a perfect, custom fit designed specifically for 6” and 8” 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 6” or 8”, simply adjust the Velcro for the correct fit.

First night using this shield and i had a light layer of dew on the lens. This did not work at all. For a little extra i wish i had bought a celestron dew heater ring. Not happy at all,
Dear Customer
Thank you for reviewing the product. May be we can help further….
Dew forms on surfaces due to differences in air temperature & also in precipitation. There are times when a lens hood, like yours, is all you need. On others a dew heater strap will be needed too.
Imoportantly, dew condensdation can be made by the air inside the optical tube being a different temperature to the outside air. Having the telescope outside 45 minutes prior to viewing is essential.
Your lens hood will deal with dew fall precipitation (rather than condensation) & also stray light pollution. You can still fit a heater strap with your hood too. Our products are here:
