I found a cool looking mesh of Charon on the 3D Asteroid Catalogue, and thought it would look good in Celestia. The only problem is that the lines that separate the "data" regions from the "no data" regions are very visible, and make the mesh look bad in Celestia:
Is there a way to remove these lines, or at least smooth them out so that they aren't visible on the dark side of Charon?

Note that the model is already correctly oriented, so please avoid changing the orientation, if possible.
