Dew is a problem of the past with AstroZap’s line of dew heaters. These are some of the simplest yet important accessories you could ever need for your telescope system. AstroZap Dew Heaters are wrapped around your telescope and heat up your OTA just enough to keep your optics free of moisture. These come in varying sizes for eyepieces and the wide selection of telescopes on the market today. If you’re in an area that gets a lot of dew, you’ll want to make sure you have one of these ready.

When operating at full power, the AstroZap Dew Heater draws 0.5 amps and much less when operating at lower power. Each heater comes with a standard six-foot cord and phono-plug connector for 12-volt operation.

Please note: a dew system controller is required to supply power and operate this accessory. AstroZap Dew Heaters are compatible with standard dew controllers.
