I noticed this strange glitch in the Moon's orbit display:



I'm running r4473 of the Win32 exe with all the latest files updated from Sourceforge. The only setting I have changed in the config is to make OrbitPathSamplePoints 360 instead of the default 100.

I'll experiment to see if this is the cause...

EDIT:

Ok, I changed the CFG back to 100 and even though the jagged bend disappears there is still a noticable bend in the orbit if you follow the Moon around at a distance of around 10 radii.

The Moon's orbit is not a closed ellipse. At the end of each orbit around the Earth, it's at a slightly different location.

Celestia orbit path routine just connects all of the calculated positions, including connecting the last point to the first. It could avoid that last connection, perhaps, but the gap would look just as strange, just different.
