[. . . ] If dew has already formed on the corrector lens, then it is too late to use the Dew Zapper effectively. Try bringing the optics indoors to dry out or use a hair blower to clear the moisture from the optics. Once the dew has been removed, the Dew Zapper can be properly employed to prevent further moisture from fogging the view. Specifications 5" 12v DC Model #3515 Heat Output: 20 watts Input Current: 1. 7 amp 6" 12v DC Model #3513 Heat Output: 20 watts Input Current: 1. 7 amp 8" 12v DC Model #3503 Heat Output: 20 watts Input Current: 1. 7 amp 10" 12v DC Model #3506 Heat Output: 20 watts Input Current: 1. 7 amp 11" 12v DC Model #3512 Heat Output: 20 watts Input Current: 1. 7 amp Installation Wrap the Dew Zapper's heating element band around the front cell casting that holds the telescope's corrector lens in place. If you are using the Dew Zapper with a lens shade, position the heating element on the telescope tube just behind the front cell casting. For the best heat conduction, be sure the heating element makes complete contact with the metal; avoid screws or bumps. For forkmounted SCTs route the cable over one fork arm to avoid tangling the cord as the telescope is moved. [. . . ] Typically, a normal car battery should provide plenty of power to run the Dew Zapper and a telescope drive system for a full night of observing.
