SBIG Tracking Cable
Standard 14 ft (4.2m) tracking cable used with SBIG cameras.
Use this to connect the guide port on your SBIG camera to the guide input port on your telescope mount.
This is a “flipped” cable, the standard for telephone-style cable wiring, where the left-most conductor on one end becomes the right-most conductor on the opposite end. It has the 6p6c RJ-12 style modular telephone connector.
When people refer to the “ST-4” guider port or more correctly “SG-4” port, this is the cable that fits the port.
