AstroZap Flexi-Heat Telescope Dew Shield for 12″ SCT Telescopes – AZ813 Astrozap

AstroZap Flexi-Heat Telescope Dew Shield for 12″ SCT Telescopes 

Bring on the heat with AstroZap’s Flexi-Heat Dew Shield!

This AZ-813 Heated Dew Shield is fitted specifically for a Meade 12” SCT or optical tubes with an outer diameter of 346 mm.

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!

Please Note:  This Astrozap Flexi-Heat Dew Shield does not work with the Meade LX850 ACF telescope.
