Celestron Smart DewHeater Controllers

Celestron Smart DewHeater controllers power dew heater rings and adjust their output automatically from ambient temperature and humidity, so optics stay clear without wasting battery. The Smart Dew Heater Controller 2x drives two heaters and the 4x drives four, enough for a main tube, guide scope, finder and eyepiece.

The optional thermistor measures the temperature of the optic itself for more precise control. They pair with Celestron dew heater rings for SCTs and refractors.
