Astrozap Flexi-Heat Dew Shield for Meade 16" SCTs

AstroZap Flexi-Heat Dew Shield for Meade 16" SCTs

If you’re running a Meade 16" Schmidt-Cassegrain, you’re no stranger to serious aperture—and serious dew problems. That massive corrector plate is a magnet for moisture, especially during long imaging sessions or high-humidity nights. The AstroZap Flexi-Heat Dew Shield gives you the muscle you need to fight back, combining passive shielding with built-in active dew control in one professional-grade package.

This heavy-duty dew shield is constructed from durable, flexible ABS plastic with a black velvet-lined interior that absorbs stray light and reduces radiative cooling. The result? Better contrast and delayed dew formation. But what sets this shield apart is the integrated low-wattage heating element, which wraps around the front of the OTA and plugs into a standard RCA-style dew controller (sold separately). This delivers gentle, even warmth to the corrector plate, keeping your view crystal-clear even during all-night sessions.

The wraparound design installs easily with a Velcro fastening strip, hugging the scope securely without tools or hardware. Designed specifically for the large front cell of the Meade 16" SCT, this Flexi-Heat model ensures perfect fit, reliable heating, and long-term durability.

Features:

• Custom-designed for Meade 16" Schmidt-Cassegrain telescopes

• Combines dew shield and heater strip into one integrated unit

• Built-in RCA connector compatible with most dew controllers

• Velvet-lined interior reduces stray light and helps insulate optics

• Velcro closure for fast, secure, tool-free installation

• Heavy-duty design built to withstand large-aperture field use

Observing Tip:

The Meade 16" SCT collects an incredible amount of light—but dew doesn’t care how much aperture you have. In fact, the larger the corrector, the faster it can fog over. A heated shield like this one is essential to keep your big glass dry, especially if you’re imaging or hosting public outreach events where clear views are critical.
