The Celestron Thermistor for Smart Dewheater Controllers works in conjunction with Celestron's Smart DewHeater Controllers to allow "smart" control of third-party dew heaters.

The Celestron Dew Heater Ring is the ideal dew prevention solution for your Celestron telescope. 

The Dew Heater Ring permanently mounts to your 8" Celestron Schmidt-Cassegrain, EdgeHD, and RASA optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).

• This Aluminum Dew Shield with Cover Cap fits all 6” Celestron Schmidt-Cassegrain telescope tubes. It’s an essential accessory that protects the tube in the field. The dew shield reduces radiative cooling of the Schmidt corrector lens to the night sky, keeping the lens below the dew point longer and preventing dew from forming on the lens. The Aluminum Dew Shield also increases image contrast by blocking stray light from entering the telescope for better viewing and astroimaging. Use the Aluminum Dew Shield on your 6” Schmidt Cassegrain telescope tube confidently, knowing it was created for your exact instrument.
