I am preparing a presentation on the Equation of Time and have been trying
to find a clear description, preferable with diagrams, of the adjustment
due to obliquity.

The explanation at the National Maritime Museum
http://www.nmm.ac.uk/server/show/conWebDoc.351 only makes sense if you
already know the answer

The best I could find was the page at
http://www.wallingfordclock.talktalk.net/Sidereal%20Time.htm but I still
find it inadequate.

The example of the bus going down the incline is good to show the slowdown
but I cannot find anything appropriate to explain the speeding up.

Has anyone seen and better presented explanations?
