Astrozap Flexi-Heat Dew Shields
Astrozap Flexi-Heat Dew Shields combine the benefits of a dew shield and dew heater in one integrated package. They direct the heat right to your optical tube assembly, thus eliminating any chance of dew formation. Flexi-Heat dew shields require a 12 Volt DC power source and dew heater controller to modulate their output. They are fitted with standard RCA jacks and are compatible with dew heater controllers sold by Astrozap, Thousand Oaks Optical, and others.
