Astrozap For Celestron 3.5" C90 or Meade ETX-90 Maksutov, Flexible Black Plastic

AstroZap Flexible Dew Shield for Celestron C90 & Meade ETX-90 – Black Plastic

Don’t let their small size fool you—Celestron’s C90 and Meade’s ETX-90 Maksutov-Cassegrains are mighty performers in compact packages. But even these go-anywhere scopes are vulnerable to dew and contrast-killing stray light. The AstroZap Flexible Dew Shield is the perfect lightweight armor for these Maks, helping you stay dew-free and focused on the stars.

Made from durable, flexible black plastic, this dew shield wraps around the front of your OTA and fastens securely with a Velcro strap. Inside, the black felt lining absorbs stray light and slows thermal radiation from the corrector lens—both of which help reduce dew formation and boost contrast.

Designed specifically for Celestron’s 3.5" C90 and Meade’s ETX-90, this dew shield rolls up easily for transport and storage, making it an ideal companion for backpack astronomy, outreach events, or casual sessions under the stars.

Observing Tip:

Compact Maks like the C90 and ETX-90 are highly portable but cool quickly—making them surprisingly prone to dew. A simple, flexible dew shield like this is one of the easiest upgrades to protect your optics and improve visual contrast, even in city skies.
