Course notes from my session called "Astrometry" at NASTRO are available by clicking the link.
The PDF has Flash animations from University of Nebraska-Lincoln embedded in it. When you open it, you'll have to enable them to run. It usually means clicking a little toolbar at the top of the talk. For best results press ctrl-L to view in full screen after you've done that.
You can view the Flash animations online if you prefer. These are the ones I showed during the talk:
Altitude/Azimuth (Horizon coordinates)
Right Ascension / Declination (Equatorial coordinates)
Coordinate Systems Comparison
There are loads more at the UNL website on other topics. Enjoy!
