Celestron Aluminum Dew Shield & Cap for 6" SCT OTA - 94020

This Celestron Aluminum Dew Shield with Cover Cap fits all 6” Celestron Schmidt-Cassegrain telescope tubes made from 2006 on.  A dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, keeping the lens below the dew point longer and preventing dew from forming on the lens. The 6" Aluminum Dew Shield also increases image contrast by blocking stray light from entering the telescope for better viewing and astro-imaging.

The exterior of the Celestron 6" dew shield is a rigid, aluminum cylinder that will not fold, flex, or deform. Inside, a velvet-lined interior absorbs any additional stray light and excess moisture, creating optimal contrast when viewing and imaging. Attach the dew shield to your telescope tube with the two adjustable clips to ensure a snug fit. It also attaches nicely to telescopes that have been fitted with the Celestron Dew Heater Ring, which is sold separately.

The cover cap is also constructed from durable yet lightweight aluminum. When your telescope is not in use, place the cover cap on your dew shield to protect your Schmidt corrector from stray dust particles. The cover cap also offers you the ability to quickly and easily acquire dark frames for imaging.

All Celestron Aluminum Dew Shield’s have an integrated cable management slot at the base. This slot gives you an easy way to corral essential cables (like the ones for our Dew Heater rings) without potentially allowing light pollution to leak in. Also, there are cutouts to accommodate dovetail rails on the top and bottom of the telescope tube, ensuring a good fit regardless of the configuration.
