I have Sky Safari 6 plus version 6 running on an mac book air. I am using a sky fi device. I am trying to connect to sky watcher EQ6_R mount. The computer connects to the ski fi connection but then cannot connect to the telescope. The error message is 'Sky Safari 6 plus can not make tcp/ip network connect to the telescope' As far as I can tell everything is correct. Telescope type, cable connections, battery charged, etc. I read about the PC direct and that is been turned off. The mount works fine with the hand controller.
