Item #  03503

With an Orion Dew Zapper, you'll never have to stop observing to remove condensation from the front plate of your Schmidt-Cassegrain or Maksutov-Cassegrain.

An unprotected corrector lens will radiate heat, quickly cooling to below ambient air temperature, allowing dew to form. The Orion Dew Zapper gently replaces lost heat, bringing the temperature of the corrector lens back above the dew point. Dew can't form, and you never get "heat wave" disturbances like those caused by warm-air blowers and heated dew caps.

The flexible, fiberglass-reinforced heating element straps securely in place on the telescope with a Velcro fastener.

Runs on 12-volt DC power. Plugs into a car cigarette-lighter receptacle or a "field battery," delivering up to 20 watts, 2 amps. All models include a 10' cable.
