Take the guesswork out of using third-party heating bands or straps and increase your power efficiency with the Celestron Thermistor for Smart DewHeater Controllers. 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. 6’ 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.

NOTE: Heating Band Not included.

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 your dew heater needs to keep the optics clear.

The Astrozap AZ-114-C Flexi-Shield® is a flexible dew shield sized for the Celestron 14" Schmidt-Cassegrain. This version has no dovetail notch and fits C14 OTAs on CGX-L mounts.

Serious aperture needs serious dew protection

The C14's huge corrector plate is a dew magnet. A passive Flexi-Shield is the single most effective, power-free way to keep it clear through a long night of observing or imaging, while also cutting stray light for improved contrast on deep-sky targets.
