Complete Telescope Power HubIntelligent Dew Control and Power Management
The Smart DewHeater and Power Controller 4X prolongs battery life while providing complete telescope power management for your entire astrophotography setup. Equipped with real-time environmental sensors, this controller monitors ambient humidity and temperature to dynamically adjust heat output across four separate dew heaters. Simplify your field operations with centralized 12V DC power ports and an integrated USB 3.2 hub designed for maximum efficiency.
Advanced Observatory Power SolutionPrecision Dew Control and System Powering
Take control of your night sky imaging with the Smart DewHeater and Power Controller 4X. Designed for serious amateur astronomers and astrophotographers, this robust dew heater controller optimizes power distribution to keep optics clear of moisture without draining your battery unnecessarily. Featuring an onboard microprocessor, the unit computes sensor readings constantly to apply just enough thermal power to up to four connected heating bands or Celestron Dew Heater Rings. Beyond dew control, it serves as a central astrophotography power hub, providing four 12V DC ports—including one variable voltage port adjustable from 3V to 12V—to power cameras, mounts, and focusers. Integrated into a durable aluminum housing with an active cooling fan, the unit connects directly to your PC via CPWI telescope control software or NexStar+ hand control for complete monitoring.

Frequently Asked QuestionsEverything you need to know
What is the main purpose of the Smart DewHeater and Power Controller 4X?
The Smart DewHeater and Power Controller 4X prevents dew formation on telescope optics while serving as a centralized power and USB distribution hub for your entire astrophotography rig.
How does the Smart DewHeater and Power Controller 4X optimize power usage?
It uses an onboard microprocessor along with integrated environmental and thermistor sensors to dynamically calculate and output only the exact amount of heat required to prevent dew.
Can I use third-party dew heater straps with the Smart DewHeater and Power Controller 4X?
Yes, it is compatible with third-party heating bands and straps when paired with the optional Celestron Thermistor for Smart DewHeater and Controllers.
How do I power the Smart DewHeater and Power Controller 4X?
It operates on a 12V DC battery source, connecting via the included 10 ft cigarette lighter to XT60 cable or through a threaded 12V DC barrel connector, handling up to 240W (20A max).
How can I control and monitor the Smart DewHeater and Power Controller 4X settings?
You can monitor real-time data and manually adjust individual port power via Celestron CPWI telescope control software on a PC or using NexStar+ / StarSense hand controls.
