[. . . ] 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.
