Re: precession
Hi,
The current versions of SharpCap include the position of the pole in J 2000 coordinates out to the year 2035. When 2035 gets a bit closer I will update to include a longer time line of data for the polar position, but since the polar position data is stored in a text file (npole.txt) in the install directory, it would be perfectly possible for users who live for hundreds of years to update that file themselves!
Cheers, Robin
