Overview
SummitLink makes this custom aux port splitter to take one Celestron aux connection and fan it out to three. The plug goes into the mount or controller aux socket and the extra ports let StarSense and SkyPortal accessories share that single line. It is a passive wiring adapter, so the listing shows no power supply or cable of its own.
Celestron mounts often have fewer aux sockets than the accessories people want to run, and this adapter opens that one socket into three. The listing backs only the StarSense and SkyPortal pairing and the physical size, so how the split behaves with other accessories, and how long any attached cable can be, stays unstated. Treat it as a port multiplier for that named gear, not a powered hub.
Who it's for
Owners of Celestron mounts who want StarSense and SkyPortal accessories connected at the same time through a single aux port. It does not suit setups that need active power distribution, long cable runs, or use with another brand of telescope mount.
Pros and cons
- Fans one Celestron aux port into three
- Built for StarSense and SkyPortal gear
- Small and light on the mount
- Simple plug-in adapter with no setup
- Cable length not listed
- Power source not listed
- No other accessories named as compatible
- Not a hand controller or mount
Performance notes
Because the adapter only reroutes the aux line, what the mount and the attached accessories can do over that single connection decides the result. Anything needing its own power or a longer run than the listing states is outside what this part is shown to handle.

Frequently asked questions
How do I care for the SummitLink aux splitter once it is plugged in?
Leave the plugs seated in the aux sockets and avoid pulling on the connected cables, since the listing gives no strain relief or cable length. Keep the splitter out of wet or dusty conditions and check the connection if an accessory stops responding.
What does the SummitLink splitter connect to?
It connects to a Celestron aux port and splits it three ways, and the listing names StarSense and SkyPortal as the compatible accessories.
Can I use the SummitLink splitter with a non-Celestron mount?
The listing names only Celestron StarSense and SkyPortal compatibility, so use with another brand of mount is not covered.
