Protect your Schmidt-Cassegrain / EdgeHD / RASA Telescope from dew with the Celestron Dew Shield DX for 6" & 8" OTAs.

The Celestron Dew Shield DX for 6-8 SCT Tubes is an essential accessory for Celestron C6 and C8 telescopes, including Schmidt-Cassegrain (SCT), EdgeHD, and RASA optical tube assemblies (OTAs), particularly in colder climates. This flexible, lightweight dew shield is designed to prevent condensation on the corrector plate—especially when a warm telescope is moved into a cold environment. Made from durable Polyethylene (PE) with a felt-lined interior, this dew shield enhances image contrast by reducing stray light and moisture that can interfere with your telescope's view.

The dew shield for 6-8 inch SCT telescopes features a wide cutout to accommodate larger dovetail rails—including the 4” Losmandy-style (CGE dovetail). Whether you're using a Celestron 6” SCT, C8, EdgeHD, or a 6” RASA, the Dew Shield 6-8 is a must-have for uninterrupted observing. 

This dew shield for C6 C8 tubes is specifically tailored to fit Celestron's 6-inch and 8-inch OTA designs.
