Celestron AUX Power Cable for Smart DewHeater Controllers
Unlock Full AUX Port Functionality—Even with Non-Celestron Mounts
If you’re using a Celestron Smart DewHeater Controller with a non-Celestron computerized telescope mount, you might notice something missing: power to the AUX ports. That’s where the Celestron AUX Power Cable comes in.
This handy accessory allows your Smart DewHeater Controller to deliver power to connected devices like the Celestron Focus Motor or SkyPortal WiFi Module, even if you’re not using a Celestron mount. It’s a simple, elegant solution to ensure your entire setup communicates and powers correctly—no matter whose name is on the mount.
Why You Need This Cable
Celestron mounts automatically supply power to AUX ports when connected to the Smart DewHeater Controller via the standard AUX cable. But third-party mounts—including popular options from Sky-Watcher, iOptron, and others—don’t provide that same AUX power path. Without this cable, the controller’s auxiliary ports remain inactive.
By plugging this cable into one of the controller’s 12V DC power outputs and an open AUX port, you bypass that limitation. This ensures all remaining AUX ports on the controller receive power for your accessories to function as intended.
Quick Setup, Reliable Power
Installation is easy: simply insert the 5.5mm/2.1mm barrel connector into a powered DC output on your Smart DewHeater Controller, and plug the RJ-25 (6P6C) modular connector into any one of the controller’s AUX ports. Now, every AUX port on the device will be fully powered and operational—ready for WiFi, autofocusing, and beyond.
The cable features a coiled design to reduce slack and minimize tangles, with a relaxed length of 250mm—just enough reach without cluttering your setup.
Important Note:
If you're already using a Celestron GoTo mount, you do not need this cable. AUX power is already supplied through the existing connection between the mount and the controller. This cable is only necessary when operating the Smart DewHeater Controller independently of a Celestron mount.
Final Thoughts
The Celestron AUX Power Cable may be a small accessory, but for those running mixed-brand setups or third-party mounts, it can be absolutely essential. Without it, key features like autofocus or wireless control may be left in the dark—literally. Add one to your kit and enjoy seamless integration across your astronomy accessories, no matter what gear you use.
