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