The Celestron Smart DewHeater and Controller 4x gathers and analyzes information in real time to warm your optics just enough to prevent dew. The device can control four dew heaters at once (one for an optical tube, another for a guide scope, another for an eyepiece, for example). It has four 12 VDC output ports that can power your mount, focus motor, camera, etc., and one of the ports has variable voltage, which you can adjust from 3V to 12V. In addition, the controller features three powered USB ports.

At the heart of the controller is a powerful microprocessor that gathers information from the sensors, computes the data, and automatically adjusts your dew heaters. The controller monitors the ambient temperature and humidity using its integrated environmental sensor and monitors the heaters' temperatures using thermistors. You can run the Smart DewHeater and Power Controller 4x as a standalone accessory. Or, if you want to view data from the controller and make manual adjustments, you can connect it to your Celestron telescope's hand control or your PC. The controller works with NexStar+ or StarSense hand controls running the latest firmware or Celestron CPWI telescope control software, included with every Celestron mount.
