AstroZap Flexi-Heat Telescope Dew Shield for 6" Meade Light Switch with Notch

The Heat is On with Flexi-Heat Dew Shields!

The AZ-102 Heated Dew Shield is custom fitted for the Meade 6" LightSwitch or optical tubes with an outer diameter of 178 mm.  A notch is cut out of the dew shield to accommodate a side bar.

Until now, standard unheated dew shields could only prolong the onset of dew formation. Depending on your geographic location, a simple dew shield may be all that is required. (Dew shields are also great for blocking stray light from reaching your optics.) However, in moist climates, dew can still creep up on you within a short period and your viewing session is over. Why not add some heat?


Our Flexi-Heat dew shields direct the heat right to your optical tube assembly, thus eliminating any chance of dew formation. Guaranteed!

What makes it work?

The source of heat is a thick film heater manufactured for operation at 12 volts. Sixty-six percent of the surface area is heat emitting - this means more even heat distribution and no localized hot spots or burnouts often associated with resistance wire heaters. Best of all, it won't create heat wave disturbances.

Our Flexi-Heat dew shields come with a six foot phono-plug cable. You will need an Astrozap dew controller for a power source. Other brand controllers are fully compatible.


The Astrozap Flexi-Heat dew shields are made from durable yet light weight ABS plastic and lined with black felt to help increase contrast. A 2-inch sewn neoprene rubber “Mega Grip” material wraps snugly around the telescope optical tube assembly, keeping the dew shield in place, and eliminating any chance of dew formation!

Madison ★★★★★

Finally got a clear night and this shield kept the optics bone dry through hours of humid observing. The snug custom fit around the 6" Meade is perfect, and the gentle heat really does stop fog before it starts. Money well spent.

Timothy G. ★★★★★

Had a horrible dewing problem during a humid night of Jupiter imaging, but this shield kept the corrector plate bone dry the entire session. The flexi-heat element warms up evenly and doesn't create any thermal ripples in the views. Exactly what the Light Switch needed.

Emma ★★★★★

Slid right onto the 6" Meade with the notch lined up perfectly, and the Flexi-Heat kept the glass crystal-clear through two hours of sub-40° observing. I was skeptical about the integrated heat, but it’s subtle, quiet, and totally worth the peace of mind.
