About this product
This accessory allows the Smart DewHeater Controller (sold separately) to deliver just the right amount warmth for to your telescope’s corrector to prevent dew without wasting battery.
Six-foot cable length accommodates a wide variety of configurations.
How it works
Connect the heating band to your telescope and place the Thermistor's sealed probe tip under the heating band. Plug each cable into its corresponding port of the Smart DewHeater Controller.
NOTE: This thermistor is not required if you are using a Celestron Dew Heater Ring because the ring already contains a built-in thermistor.
Enhance your setup
We also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the your dew heater needs to keep the optics clear.
- Works in conjunction with Celestron's Smart DewHeater Controllers to allow "smart" control of third-party dew heaters
- Regulates heating bands or straps to conserve power by only delivering enough heat to the optics to prevent dew
- Sealed tip positioned under the heating band or strap provides accurate temperature readings
