The Shoestring USB 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.
Thanks to webcam technology, it is now easy and much less expensive to set up your own autoguiding system. You’ll need a PC or laptop computer, a webcam or other video device, autoguiding software, and some sort of interface so that the computer can talk to your telescope mount and direct it’s motion. Of course, you will also need a telescope mount that is capable of receiving tracking correction commands. To use our products shown below, your mount will need an ST-4 compatible guide port.
