Thousand Oaks Dew Heaters
Dew heaters are used to prevent condensation on telescope objectives and eyepieces when high humidity and cooler temperatures combine. Thousand Oaks Optical produces our most popular dew heater controller and a selection of dew heater bands to fit most telescopes and accessories. These heater bands wrap around the front of your telescope and form a loop with themselves with an elastic band and Velcro extension. They feature a standard RCA jack connection and require a dew heater control with 12 volt DC power source to operate. Don't forget that dew will also form on your eyepieces, so it is best to equip both ends of your telescope.
