Product information

The sSynScan USB adapter allows a more reliable wired connection between any Skywatcher Synscan Go-To mount and a PC and certain Android devices. The adapter plugs into the mounts hand control port and connects to a computer with a USB cable (printer type - not supplied). Users can then control a Skywatcher Go-To telescope from a computer by using either the SynScan Pro application for Windows or third party applications like EQMOD and K-Star. The dongle is supplied with cables that support both alt-azimuth and equatorial Synscan Go-To mounts (except the EQ6 Pro when the mounts handset cable should be used instead). The dongle can also be used for updating the mount's motor firmware.
