Interesting link Slice, but I'm not really sure it answers Mikes question. It only
talks about positions and how they relate to seasons. It makes no reference
to Earths axis tilt in relation to the orbital plane of the moon. Yes mike I reckon
you are correct, I think there is a difference of 5 or 6 degrees either to our
polar axis or the orbital plane cant remember which one. Perhaps someone
else can give the details...
