I was looking at the august 11th, 1999 european solar eclipse from the Earth surface. Looking up at the sky I noticed that the sun's disk is greater then the moon's one, while the moon in reality hided completely the sun. Probabily there are some problems with the diameter of sun or moon, because the time and location of both, moon and sun, seems correct because the eclipse does appen.
About the rendering I'd like to point out that the atmosphere is not obscured by the moon shadow. Ok, Celestia is not based on a ray tracing engine, but it is not really possible to project the shadow texture also on the atmosphere?
Eclipses rendering and precision

That would be cool
looks at this screenshot, with atmosphere

The atmosphere of the sun causes the problem that the sun is bigger than the moon
