RE: Nexstar Sim Software
Yup, suggest the full sim or if cost is an issue, you can find used ones around the forums just make sure it's at least a RF 3.0 (which can be upgraded to ver. 3.5 for free online) or higher version. The computer hardware requirements for the RF software go up in a hurry after 3.5. If you do buy used, make sure it has the controller as it won't work without it and that the previous owner has "un-registered" it with Real Flight or you cannot get any updates or support.
