AUX Port Splitter Celestron 93919 — black accessory for telescope AUX port

The Celestron AUX Port Splitter 93919 is a compact black accessory designed to expand the auxiliary connectivity of compatible Celestron computerized mounts. This parallel adapter plugs into a single AUX or hand controller port and provides two 6-pin auxiliary outputs while preserving the original input, allowing simultaneous connection of the hand controller and an additional peripheral such as the Celestron StarSense AutoAlign or other AUX-compatible devices.

Advantages

The splitter delivers a simple, no-modification solution to add an extra AUX port without altering the telescope or mount. Its compact form factor keeps additional cabling and connections tidy and reduces the need to swap devices during observing sessions. By providing parallel outputs, it enables concurrent use of the hand controller and another accessory, improving convenience when setting up and operating the mount.

Suitable for

• Observers who need to connect the Celestron StarSense AutoAlign while keeping the hand controller attached
• Users adding auxiliary accessories to a mount that has only a single AUX port
• Field setups where quick connection and disconnection of multiple 6-pin AUX devices is required

Key specifications

• Connector configuration: one 6-pin input and two 6-pin outputs
• Color: black
• Function: parallel splitting of a single AUX port into two auxiliary connections
• Compatibility: designed for use with Celestron mounts and AUX-compatible Celestron accessories

How to use

Plug the splitter’s single input connector into the mount’s AUX or hand controller port. Connect the hand controller to one of the splitter’s outputs and attach the accessory device, such as the StarSense AutoAlign, to the second output. Ensure all connectors are fully seated and route cables to avoid strain. Power on the mount and connected devices following their individual startup procedures; the splitter requires no power or configuration.

Usage recommendations

Use short, properly routed cables to minimize tangling and reduce mechanical stress on connectors. Verify accessory compatibility with the mount’s AUX interface before regular use and keep the splitter dry and protected from extreme conditions to maintain reliable electrical contact.
