The simple solution to dew on your telescope, simply wrap around the optical cell and plug in to any 12 volt power source with a standard cigar lighter socket. Supplied with a lead ten feet long this dew heater band combats dew without the fuss or added cost of a seperate dew controller. This model is designed for most telescopes with an 8" aperture such as Meade or Celestron 8" SCT ranges.
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 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 power tank delivering up to 20 watts, 2 amps. All models include a 10' cable.

Electronic dew elimination system keeps dew from forming on the corrector lens
