With the right cable, connectors and software you can drive your hand controller, and thus your mount, using ASCOM 5.5 (the freeware, general purpose astronomy abstraction communications software layer) from any popular astronomy program, from the freeware Cartes du Ceil all the way up to the expensive The Sky X Professional Edition.
Suggest Google ASCOM

These abstraction layers and more powerful telescope pointing systems offer alot more joy then the boring Nexremote!
