Does anyone know of a website or even have a handy-dandy formula for backtracking the declination and RA of a star for, say 10,000 years? Or, just give a decl. and RA and the pop in the number of years back to get a new value?I suppose I could figure it out myself, but I'm lazy and having something simple would help.
