HI there,(adsbygoogle = window.adsbygoogle || []).push({});

I am having problems understanding something.

If I have an axis pointing towards the galactic north pole, and I rotate it using an Euler rotations how can I can I establish the rotation angles needed so that it will be pointing to the equatorial North pole.

I am looking for values alpha and beta where alpha can run from -pi-->pi and beta can run from -pi/2-->pi/2.

Many thanks
