I too have stumbled upon Celestia in the last 24hrs and I'm wanting to use it to show the 11/08/99 eclipse in a class next week. After tweaking the render mode, I've got Celestia working on my laptop, but when I try to show the shadow tracking across the earth, I'm seeing several shadows (sometimes 3 at once) tracking across the globe in all sorts of strange directions.
Has some kind person got some insight into what I'm seeing? Is this:
+ The shadow of something else (looks big!). I'm afraid I've had no joy landing on earth and trying to look up to see what it is (how do you "look behind you?").
+ An artifact of using a non GL render mode (these appear in both the basic and multitexture modes - I'm afraid that the OpenGL mode draws a bizarrely ellipsoid earth and then promptly crashes Celestia)
+ A known bug of some other kind (in which case, with heavy heart, I'll pursue Starry Night or Redshift)
Any help gratefully received
