  • Celestron AUX Port Splitter

    The Celestron AUX Port Splitter instantly expands your computerized mount's connectivity by turning a single AUX or hand controller port into two. This simple adapter is the solution for running modern accessories like the StarSense AutoAlign without having to disconnect your NexStar+ hand controller, and comes with a 2-year warranty for peace of mind.

    Add a Second AUX Port to Your Celestron Mount

    Modern astronomy accessories often compete for the single auxiliary port available on many Celestron computerized mounts. The Celestron AUX Port Splitter resolves this by providing a clean, parallel connection that lets you plug in two devices simultaneously. It's an essential upgrade for anyone looking to expand their setup's capabilities without complex workarounds.

    Run 2 Accessories Simultaneously: StarSense and Hand Control

    The most common use for this splitter is to enable the use of a Celestron StarSense AutoAlign accessory alongside the standard hand controller. Simply plug the splitter into the mount's AUX port, then connect both the StarSense and the hand controller to the splitter. This allows you to leverage the power of automated alignment while retaining full manual control and access to the hand controller's database.

  • What is the Celestron AUX Port Splitter used for?

    The Celestron AUX Port Splitter is designed to solve the problem of having too few auxiliary ports on your Celestron computerized mount. It plugs into a single AUX or hand controller port and provides two ports in its place, allowing you to connect multiple accessories at the same time.

    Can I use the Celestron AUX Port Splitter with a StarSense AutoAlign and my NexStar+ hand controller?

    Yes, this is its primary function. You can connect both the StarSense AutoAlign and your hand controller to the mount simultaneously, eliminating the need to swap cables. This is especially useful on mounts like the Advanced VX or NexStar SE series.

    Will this splitter work with my Celestron CGEM II mount?

    Yes, the Celestron AUX Port Splitter is compatible with any Celestron computerized mount that uses an AUX port, including the CGEM II, Advanced VX, CGX, NexStar SE, and CPC series telescopes. It plugs into either the dedicated AUX port or the port intended for the hand controller.

    Does the Celestron AUX Port Splitter introduce any signal delay or power issues?

    No, the splitter is a passive parallel adapter. It is engineered by Celestron to ensure that both connected devices receive the necessary power and data signals to function correctly without interfering with one another.

    Can I connect two hand controllers to the Celestron AUX Port Splitter?

    No, the splitter is not designed to operate two primary control devices simultaneously. It is intended for connecting a primary controller (like the NexStar+ hand controller) and a peripheral accessory (like StarSense, a WiFi module, or a focuser).

    Is the Celestron AUX Port Splitter difficult to install?

    Installation is extremely simple. Just unplug your hand controller, plug the AUX Port Splitter into that port on the mount, and then plug your hand controller and your second accessory into the two ports on the splitter. No tools or software are required.
