I was dealing only with the imaginary celestial pole of an imaginary celestial sphere. ..So now I have to aply my logic to the eclipticBut I'm having difficulty with what you mean by ecliptic pole.wiki says,"The ecliptic is the apparent path that the Sun traces out in the sky, as it appears to move in the sky in relation to the stars, this apparent path aligns with the planets throughout the course of the year. More accurately, it is the intersection of the celestial sphere with the ecliptic plane, which is the geometric plane containing the mean orbit of the Earth around the Sun. It should be distinguished from the invariable ecliptic plane, which is the vector sum of the angular momenta of all planetary orbital planes, to which Jupiter is the main contributor.
The name ecliptic is derived from being the place where eclipses occur."
You gotta admit, at least it is to me, a rather difficult definition to visualise. I am graphically disabled. This whole article gives me no picture..It seems to define the ecliptic as a circle....ie
"The ecliptic is the apparent path that the Sun traces out in the sky, as it appears to move in the sky in relation to the stars, this apparent path aligns with the planets throughout the course of the year.
and I would say it is a path around the earth geocentrically. daily...
But the sun does not move... heliocentrically it is fixed with the stars. There is no mention of ecliptic poles???
I could get no further with your site either, but maybe as you say it is upgraded.
oh my......I'll have to put this into my happy hour.. Come to think of it thats four hours away... I'll start now.. my happy hour of course.
