I have a Obsession 18UC with Argo & SkyFi III and SkySAfari via iPad.. I have no issues with them working together.
However, I have seen several instances on web pages where folks are NOT using the Argo Navis, but still controlling their telescope with SkyFi with an iPad/iPhone running SkySafari.
I am curious as to how to do this without the Argo Navis? Don't you still have to acquire an alignment with the telescope and SkySafari?
