Astrozap Flexi-Heat Dew Shield for 4" Celestron NexStar 4 and Meade ETX-105 Maksutov-Cassegrains

AstroZap Flexi-Heat Dew Shield for Celestron NexStar 4 & Meade ETX-105 Maksutov-Cassegrains

Don’t let dew ground your grab-and-go mission. Whether you’re piloting a Celestron NexStar 4 or a Meade ETX-105 Maksutov, the AstroZap Flexi-Heat Dew Shield ensures that your small scope stays sharp, dry, and ready for any observing opportunity.

This model blends passive dew prevention and contrast enhancement with active dew-fighting technology, thanks to an integrated low-wattage heating element built right into the body. The standard RCA connector plugs into your favorite 12V dew controller (sold separately), delivering just enough warmth to the corrector plate to keep moisture at bay—even on damp, dewy nights.

Crafted from lightweight black ABS plastic, this dew shield installs in seconds with a Velcro fastening strip, and features a velvet-lined interior that absorbs stray light while helping to moderate temperature differences. It's custom-fit to wrap snugly around the OTA front cell, staying secure without shifting or drooping.

Features:

• Designed for Celestron NexStar 4" and Meade ETX-105 Maksutov-Cassegrains

• Built-in RCA-compatible heater strip for active dew protection

• Velvet-lined interior suppresses ambient light and insulates optics

• Flexible black ABS plastic shell with quick Velcro closure

• Combines passive and active dew defense in a compact, travel-ready package

• Lightweight and low-profile—ideal for smaller scopes

Observing Tip:

Smaller Maks are often used for lunar, planetary, or outreach work—where crisp focus and contrast are essential. But their compact corrector plates cool quickly and can dew up faster than you’d expect. A heated dew shield like this gives your scope the same level of protection as the big boys—without the bulk.
