14. Saturn investigations: Margie's students and Yerkes Collaboration Sometimes it looks like a moon is double! ‘Poor seeing’ creates kind of a double exposure. Seeing: Different temperatures and densities of bubbles or layers of air in the atmosphere refract the light first this way, then that way.
