I discovered that it's not even necessary to select CATALOG FROM PLANETARIUM on the Argo Navis DSC when the SkyFi is connected. I inadvertently forgot to make that selection and everything worked perfectly. In fact, I could also select a star in the sky, choose ALIGN STAR on the Argo Navis and it would center that star on the SkySafari/SkyFi map. Nice, indeed. I'm all for fewer complications in this complex world.
