I can't connect to the telescope, same issue as above. Followed the "instructions" mentioned above (which give contradictory port numbers) and nothing.
Using the AZ GOTO EQ3 mount with the Synscan Wifi dongle.
I can control the telescope with the Synscan app (App 1.8.0 iOS 11.2.5), so I know the connection is good. I can also ping the wifi dongle and see it in a network sweep.
What gives? Surely somebody else got this working.
By the way, I feel the SkyWatcher "instructions" are pathetic generally.
