Thanks for the information. I would agree with you for a presentation, 
but I need it mostly this time for a paper I'm writing. I will be giving 
a talk, so I could use a video 3-D clip. However, in this case, it may 
not be useful. I'm simply trying to show three coordinate systems with 
the same origin. One is an image plane (x-y), and the other two are 
az/el, separated by an angle about the zenith. A celestial sphere needs 
to be shown with a few stars on it. I could go overboard with this, by 
rotating one of the coordinate systems around the north pole, and 
drawing the path of the stars on the sphere, but I'll worry about that 
for another time.
