Celestron Smart DewHeater Controller 2x

The Celestron Smart DewHeater and Controller 2x gathers and analyzes information in real time to warm your optics just enough to prevent dew. The device can control two dew heaters at once (one for an optical tube, another for a guide scope, for example) and features an additional 12 VDC output port so you can power another 12 VDC device, such as your mount.

The Smart DewHeater and Controller works seamlessly with Celestron's Dew Heater Rings, which have a built-in thermistor to provide temperature readings of the corrector lens. Third-party dew heater bands or straps are also compatible; you simply need to add Celestron's Thermistor for Smart DewHeater Controllers (sold separately).
