I am looking into buying a Vixen SX2 to go with my Mewlon 180c. The SX2 used to be offered with Starbook One hand controller for tracking, or with Stabook Ten for full GoTo. Now I see that on the Japanese Vixen site, and in Japanese vendor sites, The SX2 (and SXD2) are now only offered in a Wireless version. There is no hand controller and everything goes through your phone or tablet. In theory this could be a good thing, since the software contains full Starbook Ten-like capability at a price that seems to be around the old price for the Starbook One version alone. Has anyone used this Wireless only version? Does it work well? I am a little wary of switching over to complete wireless with no physical connection. But maybe it is OK. I never physically connect my computer to a network after all. I imagine that soon enough this change will come to Europe, but currently it seems still possible to buy SX2 with the Starbook One controller in Europe.
