Hi Guys, I have for sale a Shoestring astronomy guide port interface.
Good condition $50 +shipping
The GPUSB guide port interface adapter plugs directly into a USB port on your computer or a USB hub attached to your computer. Using an RJ-12 cable, the adapter connects to the guide port of your telescope mount. This guide port interface uses optocouplers to electrically isolate the computer from the telescope, eliminating a possible source of electrical interference. This interface adapter requires no external power source since it receives its power via the USB cable.
Pm me if you are interested
Cheers Clive
