## Overview

The 94021 Aluminium Telescope Dew Shield with Cover Cap is engineered to fit 8” Schmidt Cassegrain, EdgeHD, and RASA telescopes, preventing dew formation and off-axis glare. Its rigid aluminium body with a velvet-lined interior reduces stray light, enhancing image quality. Featuring two adjustable clips for easy installation and cable management for Fastar/Hyperstar setups, it ensures extended, uninterrupted observation sessions with superior lens protection.

## Description

The Celestron Aluminum Dew Shield with Cover Cap protects your telescope tube in the field. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, thus keeping the lens below the dew point longer and preventing dew formation on the lens. Also, the Aluminum Dew Shield increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. Use the Aluminum Dew Shield on your 8” EdgeHD, RASA, or Schmidt Cassegrain (made after 2006) telescope tube confidently, knowing it was created for your exact instrument.

Review: Dew shield - Well made and has done the job so far
Review: Very solidly built, and the front lid closes nicely, neatly hiding the cables for my Dew heater ring. One thing to keep in mind is the weight, so everything is balanced properly.
