Astrozap AstroStrap Dew Heater for 6" Telescopes

Do you have a problem with dew? There's a natural solution - The Astrozap AstroStrap Dew Heaters. Here's how they work... On one side of the Astrozap AstroStrap you find a sponge insulation. This keeps the warmth of the heating element directed towards your optics or appliances and saves energy while it keeps your gear moisture-free. Simply wrap the Astrozap AstroStrap Dew Heater element around your eyepiece or objective cell with the blue cloth side applied to where you want the heat. On the flip side of the AstroStrap, you'll find a black Velcro closure. Just pull the Astrozap AstroStrap tight, press the connecting Velcro tab to the back of the heater and the elastic holds it firmly in place.   When running a full power, the dew heater draws 0.80 amps and much less when operating in a normal mode. Each heater comes with a standard six-foot cord and phono-plug connector for 12-Volt operation. But remember, this is only the heater and cord... You'll need a dew system controller to sup
