Constructed from lightweight aluminum weighing just 4.69 oz, it replaces the factory retaining ring on your 11\" Schmidt-Cassegrain, EdgeHD, or RASA optical tube. Power is supplied through a standard 12V DC barrel connector, and an integrated thermistor with a 2.5mm audio jack enables intelligent power management when paired with a Celestron SmartHeat Dew Controller.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003eDirect Corrector Heating: An Efficient 30-Watt Dew Solution\u003c\/h3\u003e\n\u003cp\u003eThis ring's core advantage is its method of heat transfer.

4X\u003c\/h2\u003e\n\u003cp\u003eThe Celestron Smart DewHeater and Power Controller 4X is a complete power and dew management solution, providing intelligent control for four dew heaters and distributing power to your entire imaging rig through 10 separate outputs. With two 12V DC inputs, including a high-current XT60 jack rated for a 20A maximum input, this controller can power a mount, camera, and accessories from a single source. An integrated environmental sensor feeds data to a microprocessor, which optimizes power usage in real time to keep your optics clear while conserving battery life, all housed in a 1.4 lbs aluminum enclosure.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e4-Channel Intelligent Dew Prevention\u003c\/h3\u003e\n\u003cp\u003eThis controller eliminates guesswork by using data to apply heat precisely where and when it's needed. It features four RCA-jack dew heater ports, each paired with a 2.5mm thermistor port, allowing it to constantly monitor the temperature of your optics. The unit's integrated environmental sensor measures ambient temperature and humidity, letting the processor calculate the exact dew point and deliver just enough power to prevent condensation, significantly extending your field battery life.\u003c\/p\u003e\n\u003cp\u003eWhile the controller is designed to work seamlessly with Celestron's Dew Heater Rings (which have built-in thermistors), it is also fully compatible with third-party heating straps. To enable smart control with other straps, simply connect an optional Celestron Thermistor to the corresponding port.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"DAV-bg-light\"\u003e\n\u003cdiv class=\"DAV-section\"\u003e\n\u003ch3\u003e10 Ports to Power Your Entire Imaging Rig\u003c\/h3\u003e\n\u003cp\u003eSimplify your cable management by running your entire setup from one hub. The Controller 4X provides a total of 10 outputs to power all your equipment, protected by electronic fuses and low-voltage cut-off circuits.

Using the included AUX cable, the controller integrates with a NexStar+ or StarSense hand control. For ultimate control, connect it to a PC via the USB 3.2 Type B port to use Celestron's CPWI software.\u003c\/p\u003e\n\u003cp\u003eThis integration allows you to view real-time data from all sensors, monitor power consumption, and manually adjust dew heater output.

It mounts securely on either a CG-5 or CGE-style dovetail bar via its built-in clamp, or can be strapped to a tripod leg with the included strap. Its most unique design feature is the \"bridge,\" which arches over the main body.\u003c\/p\u003e\n\u003cp\u003eThis bridge houses the environmental sensor, thermally isolating it from the heat generated by the controller's electronics to ensure accurate ambient temperature and humidity readings.
