Overview
Unlike a powered hub, this SummitLink part is a passive splitter that turns one 6-pin auxiliary socket into two inputs feeding a single 6-pin output. It rests inline between the mount port and the accessories, so the hand controller and the StarSense camera can share the socket the mount provides. Nothing in the listing states a cable length, a housing size or any included bracket.
Celestron mounts that expose only one hand controller port leave an owner choosing between the hand controller and the StarSense camera. This splitter answers that exact conflict by accepting two 6-pin auxiliary plugs and presenting one 6-pin plug to the mount. What it does not do is add ports anywhere else, and the listing stays silent on cord length and physical size, so the fit around a crowded mount base is unproven until it arrives.
Who it's for
Owners of Celestron mounts that carry a single hand controller socket and a StarSense or SkyPortal accessory have the problem this part solves. A user whose mount already offers spare auxiliary ports gains nothing from it, and anyone expecting a powered hub or extra sockets elsewhere should look past this listing.
Pros and cons
- Two 6-pin auxiliary inputs, one 6-pin output
- Made for StarSense and SkyPortal gear
- Frees a single hand controller port
- Passive inline part, no power plug
- Cable length not listed
- Dimensions not listed
- No mounting hardware stated
- No power supply included
Performance notes
Because the splitter carries the auxiliary signal between the mount socket and the attached accessories, the result depends on how the mount polls whatever is plugged into it. Two devices sharing one port behave differently from two devices on separate ports, and the listing gives no cable length, so strain on the connector at the mount base is something the buyer controls through routing.

Frequently asked questions
What comes in the box with the SummitLink aux port splitter?
The listing gives a package quantity of one and a unit count of one, and it names no cable, adapter, bracket or power supply alongside it. Treat the splitter as the whole contents and check the run you need before ordering.
Will this splitter work if my Celestron mount already has two free auxiliary ports?
It is built for mounts with only one hand controller port, so a mount with spare sockets has no use for it. The listing ties the part to that single-port situation.
Does the splitter need its own power?
No. The listing states no plug and no power supply, so it works inline between the mount and the accessories.
Can I use it with non-Celestron accessories?
The listing names Celestron StarSense and Celestron SkyPortal as the compatible devices, and it states nothing about other brands. Anything outside those two names is unverified here.
