Astrozap Flexi-Heat® Flexible Heated Dew Shields
$175.00
Outlast the dew.
A dew shield alone only delays the fog. Astrozap’s Flexi-Heat® heated dew shields wrap your telescope in felt-lined shielding and add a sewn-in 12 V heater that holds the glass above the dew point until dawn. 46 exact fits, from 90 mm refractors to 16″ SCTs.
A shield delays the fog. Heat stops it.
Active heat. Passive shield.
Every Flexi-Heat® combines both methods of dew fighting in one wrap. The shield creates a zone of air that cools slower than the night around it, while the sewn-in heater element keeps the glass above the dew point in all but the most extreme conditions.
Blacker sky, sharper contrast.
The felt lining absorbs moisture and swallows stray, off-axis light before it reaches your optics. Streetlights and a neighbour’s porch globe stop washing out the view, so faint targets keep their contrast.
6 to 25.8 watts.
Each model’s element is matched to its tube diameter, from 6 W on a NexStar 90 to 25.8 W on a Meade 16″ SCT. Just enough warmth to stay above the dew point, never enough to disturb the view.
ABS-grade polymers.
Made in the USA from the highest quality ABS-grade polymer sheet. Padded VELCRO® Brand fasteners pull it snug around the tube without marring or scratching the telescope’s finish.
Rolls up flat.
Unwrap it and the whole shield rolls into a slim coil that slips beside your eyepiece case. It weighs next to nothing in the car for star parties and dark-sky trips.
One lead, two ways to run it.
The built-in element ends in a single 12 V lead. Run it from the Astrozap AZ-719 DC adapter for set-and-forget warmth, or an AZ-720 dual-channel dew controller to dial the heat to the night. Both sold separately.
Slow the cooling.
From sunset, your optics shed heat faster than the air around them. The wrap extends the tube and traps a pocket of slower-cooling air in front of the corrector, holding it warmer for longer, exactly like a classic dew shield.
Stay above the dew point.
Passive shielding alone is temporary; eventually the air inside reaches the dew point too. The sewn-in 12 V element adds a gentle trickle of warmth so the glass never gets there, keeping you observing or imaging until dawn.
Made for your tube.
Forty-six models cover tubes from 90 mm to 444 mm across Celestron, Meade, Sky-Watcher, Takahashi, Orion, iOptron and Unistellar. Notched versions clear dovetail bars and side rails, so the shield sits flush where it should.
Active and passive dew prevention in one felt-lined flexible wrap, for visual astronomy and astrophotography alike.
46 exact fits covering optical tubes from 90 mm to 444 mm diameter.
Integrated 12 V heater element, 6.0 to 25.8 W matched to shield size.
Felt lining absorbs moisture and blocks stray light for higher contrast.
Padded VELCRO® Brand fasteners grip snugly without marking the tube.
Notched versions clear dovetail bars, side bars and fork-mount arms.
Rolls flat for travel to star parties and dark-sky sites. Made in the USA.
Powered by the Astrozap AZ-719 DC adapter or AZ-720 dual-channel dew controller, sold separately.
