CELESTRON aluminum dew shield for SC 11" tubes
The aluminum dew shield Celestron with cover is an essential accessory that protects your telescope tube in the field. The dew shield reduces the temperature lowering effect of the Schmidt corecting plate, thus keeping the lens below the dew point longer and preventing the formation of dew on the lens. In addition, the aluminum lens hood increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. Use the aluminum lens hood on your 11" EdgeHD, RASA or Schmidt Cassegrain (manufactured after 2006) optical tube with confidence, knowing that it was created for your exact instrument.
Construction
The aluminum dew shield provides a perfect, custom fit for Celestron 11" telescope tubes. The exterior of the dew shield is a rigid aluminum cylinder that will not bend, flex or deform. On the inside, a velvet lining absorbs any additional light and excess moisture, creating optimum contrast when viewing and imaging. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a perfect fit.
We have also manufactured the cover cap from durable, lightweight aluminum. When your telescope is not in use, attach the cover cap to the dew shield to protect your Schmidt corrector from dust particles. The cover also gives you the ability to quickly and easily acquire DARK images for imaging.
If you are an astrophotographer who enjoys using your Schmidt-Cassegrain or EdgeHD in the Fastar/Hyperstar or RASA configuration, you are probably used to routing cables through the front of the dew shield. Simplify and streamline your setup with the integrated cable management slot in the base of the aluminum dew shield. This slot gives you an easy way to bundle essential cables (such as those for our heating rings) without allowing light pollution to seep in. In addition, there are slots to accommodate the dovetail at the top and bottom of the telescope tube, ensuring a good fit regardless of configuration.
Improve your setup
When you purchase this item, you will receive 2 stickers with the Celestron logo, which can be applied to the dew shield or anywhere else you wish.
