This must-have accessory will improve your observing or imaging nights year-round. The Dew Heater Ring permanently mounts to your 6\" Celestron Schmidt-Cassegrain optical tube, replacing your retaining ring, so you'll never be caught without it. The installation process is quick and easy (follow the manual for instructions).\u003cbr\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eHow it works\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe Dew Heater Ring replaces the plastic retaining ring on your Schmidt corrector lens for efficient heating across the lens. The ring is constructed of lightweight, durable aluminum. Its rigid frame supports the cable circuity and the telescope's Schmidt corrector lens. Unlike other heating bands or strips that inefficiently heat the lens cell to warm the glass, the Celestron Dew Heater Ring heats the corrector glass directly, providing the most efficient transfer of heat to prevent dew formation.\u003cbr\u003e\u003cbr\u003eSimply plug the ring into an external 12V DC power source for consistent, continuous heat that will prevent dew from forming even under heavy dew conditions. The Dew Heater Ring features two storage clips to keep the power and thermistor jacks secure when not in use while accommodating the telescope's dust cover.\u003cbr\u003e\u003cbr\u003eThe Dew Heater Ring also comes with a cable management clip that connects to the telescope's front cell. Corral the power and thermistor jack to prevent them from dangling and reduce unwanted pulls on the cable connection to the rings.\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eThe Dew Heater Ring comes complete with:\u003c\/strong\u003e\u003cbr\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDew Heater Ring\u003c\/li\u003e\n\u003cli\u003eCable management clip\u003c\/li\u003e\n\u003cli\u003ePower jack extension cable\u003c\/li\u003e\n\u003cli\u003ePaper installation shield\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eEnhance your setup\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eTo achieve the highest level of dew prevention while maximizing power efficiency, we strongly recommend pairing the Dew Heater Ring with a Smart DewHeater Controller (sold separately). The controller uses the ring's built-in thermistor and its internal environmental sensor to provide just the right amount of heat to the corrector to prevent dew based upon the ambient temperature, ambient humidity, and temperature of the Schmidt corrector, which can dramatically reduce the ring’s power draw, greatly increasing battery life. The ring also includes an extension cable for connecting the ring directly to one of the controllers’ heater output ports, or to a third-party controller’s heater output port. (Note: the ring’s integrated thermistor is only compatible with the Celestron Smart DewHeater Controllers).\u003cbr\u003e\u003cbr\u003eWe also recommend adding a dew shield to your setup. While not mandatory, a shield will cut down on the amount of power the Dew Heater Ring needs to keep the optics clear.\u003c\/p\u003e\n\u003ch3 data-mce-fragment=\"1\"\u003eTechnical Specifications\u003c\/h3\u003e\n\u003ch4\u003e5\"\u003c\/h4\u003e\n\u003ctable style=\"box-sizing: inherit;

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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe 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).\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cstrong\u003eSmart Controls\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eAt 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.\u003cbr\u003e\u003cbr\u003eYou 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.\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cstrong\u003ePower\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eNOTE: 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.\u003cbr\u003e\u003cbr\u003e \u003cbr\u003e\u003cbr\u003e\u003cstrong\u003eUnique Industrial Design\u003c\/strong\u003e\u003cbr\u003e\u003cbr\u003eThe Smart DewHeater and Controller 2x features a heavy-duty metal housing. Inside, a cooling fan protects the controller’s electronics.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eThe 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.\u003cbr\u003e\u003cbr\u003eMounting – The Celestron Smart DewHeater and Controller 2x mounts on your CGE or CG-5 dovetail with the integrated dovetail clamps.
