Featuring two dedicated dew heater ports plus an extra 12V output for accessories, it integrates seamlessly with Celestron mounts and software for full control and monitoring. Housed in a rugged metal case with active cooling and easy mounting options, this controller optimizes power use to extend battery life, making it an essential upgrade for serious astroimagers and observers who demand uninterrupted, crystal-clear views. ## Description Work smarter, not harder, when it comes to combating dew. The Smart DewHeater and Controller 2x prolongs your battery life by optimizing power usage for up to two dew heaters. The controller gathers and analyzes information in real time to warm your optics just enough to prevent dew. The Smart DewHeater and Controller comes with two ports to control two dew heaters at once. You can use one port to heat your optical tube while the other warms a second optical tube, a guide scope, an eyepiece, or another accessory. The controller also features an additional 12V DC output port so you can power another 12V DC 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). Smart Controls 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 Controller 2x 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. Power The Smart DewHeater and Controller 2x runs on a 12V DC battery (like our PowerTank Lithium Pro or PowerTank 17) and can handle a maximum power of 120W (10A max current @ 12V DC). The controller also features a 12V DC output port. You can use this extra port to power another device, like your mount. This way, you can power your entire setup from a single source. Resettable electronic fuses prevent damage if input or output current draw becomes too high. NOTE: If you are using two dew heaters in heavy dew conditions and powering a 12V DC device, the controller may be operating near its power limit. In this case, one PowerTank Lithium Pro or PowerTank 17Ah will not have enough capacity to run your setup all night; you'll need a larger capacity battery or multiple batteries. Unique Industrial Design The Smart DewHeater and Controller 2x features a heavy-duty metal housing. Inside, a cooling fan protects the controller’s electronics. The Bridge – On top of the controller, you will find the bridge, which is home to the device’s status LEDs and environmental sensors. It also helps with cable management. We have positioned the temperature and humidity sensors here, away from the control box and other components that could generate heat. Unlike competitor products, our sensors do not require additional cables to obtain accurate readings. The LED lights on the bridge indicate the device’s current status. The LEDs provide warnings if the controller is drawing more current than your power source can supply or if the battery charge needs recharging. You can dim the lights if you are under dark skies. Mounting – The Celestron Smart DewHeater and Controller 2x mounts on your CGE or CG-5 dovetail with the integrated dovetail clamps. If you prefer to mount the controller on your tripod leg, use the included strap. Smart DewHeater and Controller 2x comes complete with: Smart DewHeater and Controller 2x Tripod leg strap Controller power cable Power cable for external 12V DC device AUX cable for connecting to Celestron mounts Thermistor extension cable to attach to Celestron’s Dew Heater Ring Enhance your setup We highly recommend pairing this controller with Celestron Dew Heater Rings. They fit seamlessly on your Schmidt corrector lens and will improve your observing or imaging year-round. For the highest level of dew prevention, we also suggest adding a dew shield to your setup. While not required, a dew shield will cut down on the amount of power the controller needs to provide to the dew heater rings to keep your optics clear. Review: The Perfect Dew Controller - Absolute best few controller ever and it also powers my ZWO ASIAir Plus no problem. I highly highly recommend for auto dew control and you can easily see what is going on with CPWI. Easy install too and perfect fit. Review: It works perfectly as it should considering the price. - The smart dew heater controller is a high-quality piece of equipment that does a great job. It seems to work perfectly. My only complaint is the price. With a micro PC that has far more capabilities selling for under $200, I'm hard-pressed to justify the cost of this device. ## Features - 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 12V DC 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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09Y2HDX13 | | Best Sellers Rank | #97,766 in Industrial & Scientific ( See Top 100 in Industrial & Scientific ) #125 in Temperature Controllers | | Brand | Celestron | | Brand Name | Celestron | | Color | Black | | Customer Reviews | 4.4 out of 5 stars 56 Reviews | | Global Trade Identification Number | 00050234940351 | | Included Components | Controller | | Item Highlight | Automated Dew Prevention, Smart Temperature & Heat Output Management, Ideal for Compact Astroimaging Setups, USB-C Item Highlight Automated Dew Prevention, Smart Temperature & Heat Output Management, Ideal for Compact Astroimaging Setups, USB-C See more | | Item Weight | 544 g | | Manufacturer | Celestron | | Model | 94035 | | Number of Items | 1 | | Part Number | 94035 | | UPC | 050234940351 | | Warranty Description | 2-YEAR WARRANTY | ## Images ![Celestron Smart DewHeater Controller 2X for Telescopes – 2 Ports - Image 1](https://m.media-amazon.com/images/I/71JmQrxlceL.jpg) ## Available Options This product comes in different **Style** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ The Perfect Dew Controller *by L***S on July 2, 2026* Absolute best few controller ever and it also powers my ZWO ASIAir Plus no problem.
