Celestron Aluminum Dew Shield & Cap for 6" SCT OTA - 94020 type-correctors Remember to blow or brushThis 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
