Dear Bill,
if we make a computation of a star field on -24.000 we should have a
the ecliptical pole near to the to day position (ecliptical's grids)
but:
the pole of the ecliptical grids is out of position and also the
precession is not working properly.
I think that the polynomial approximation end to work around -10.0000.
I can modify my setting for to solve this particular problem?

Best Regards

Dario
