Guide Port Splitter
Would you like to plug in a hand controller and a computer into the guide port of your telescope at the same time? Then here is the device you need. Plug this into your guide port. Plug your hand controller into one side. Then plug the cable that goes to your guide port interface adapter into the other side. No more need to unplug one controller when you want to use the other.
Plan ahead, on some mounts there is not enough clearance around the autoguide port to plug this splitter in directly. In this case, use the guide port extension, GPEXT, to avoid the problem.
