[QUOTE="jim mcnamara, post: 5430492, member: 35824"] Short answer - what are you trying to do? Can you write programs in some language like maybe C or FORTRAN? I suppose you can use a sophisticated programmable TI calculator... [USER=42688]@D H[/USER] probably can help with a lot more detail - the JPL has software that does astronomical calculations. And copes with Jxxxx. AFAIK. Jan Meeus has several books meant for amateur astronomers. Please consider one of them as a great starting point.

All of what I did was always okay with existing ephemera. [/QUOTE]
