The HitecAstro FTDI RS232 USB Adaptor plugs into your Celestron GOTO Mount's Nexstar or Nexstar+ handset and provides direct connection with your computer or tablet, so that you can control your mount from your PC, laptop or Mac. This way you can use a third party software like Stellarium, the SkyX, Maxim DL etc to control your mount. You can also use it to update the firmware on your mount and handset via this adapter.

Please note, as far as we know, via the appropriate FTDI driver, in addition to Widnows, it is also compatible with Mac and Linux, but it has not been tested yet as we do not have such devices. We'd be glad to hear about feedback from customers...


This adapter cable is compatible with all current Celestron GOTO mounts that have a 4-pin 4-connector (RJ10 or 4P4C) socket on the handset. Obviously, it is NOT compatible with the latest Celestron Nexstar+ handsets that feature a micro USB port on the handset. Earlier Nexstar+ handsets featured the 4P4C socket, in which case this cable can be used.

Communication protocol: RS232

Chipset: genuine FTDI 232R

Available in 3m and 5m lengths.
