Thanks Chris! I don't have the direct PC control option in the utility menu of my hand controller, which is strange. The manual that my telescope came with definitely says that my telescope can connect to a PC though, so perhaps it's just later versions that have that option. And my computer does recognise that my telescope is connected. Other than that I have followed all of those steps, so I have quite a problem here!
I did manage to bypass the StellariumScope program and connect my telescope to Stellarium directly. But I can't give a stop command (easily) without shutting down the entire telescope.
So I reckon I'll try updating the version on my hand controller and see what happens (hasn't been updated in a while, so it might do some good!
)
