The Astrozap Flexi-Heat Dew Shields direct the heat right to your opticaltube assembly, thus eliminating any chance of dew formation. Guaranteed!
The source of heat is a thick film heater manufactured for operation at 12volts. 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.
The Astrozap Flexi-Heat Dew Shields come with a six foot phono-plug cable and are compatible with both the Kendrick and Dew Buster controllers. Optional cigarette lighter adapters are available for use without controllers.
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!
