Celestron 94035 Overview

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).

  • Using real-time data, the controller provides just enough heat to prevent dew from forming, prolonging battery life
  • "Smart control" system monitors ambient temperature and humidity and adjusts power to the dew heaters automatically
  • Compatible with Celestron Dew Heater Rings and third-party heating bands or straps (with thermistor accessory)
  • Supports up to two dew heaters plus one additional 12 VDC device, such as your mount
  • Works with your Celestron telescope's hand control or CPWI telescope control software so you can view data and make manual adjustments
  • Mounts securely to your telescope's dovetail or tripod leg
  • Durable metal housing features an integrated cooling fan to protect the controller's electronics

Bought this to power the Celestron Dew Heater Ring on my 11 EdgeHD. I mounted it on a CPC Deluxe 1100HD on a wide CGE style dovetail that I installed on the bottom side of the OTA. This is where I mounted the dew heater controller. It has AUX ports that you can use to network your many peripheral devices of your scope. It is easily controllable by the Celestron CPWI app and If I am not mistaken, the ZWO ASIAIR PLUS app but I have not yet tested this out. Great little dew heater regulator will save battery power when operating remote in dark sky environments. I highly recommend this to anybody who does long sittings or all nighters. Keeps the dew off your corrector plate glass and doesn't drain your power tanks, serves as a power distribution hub as well as offers some extra AUX ports for your astro rigs.
