dione & titan, photographed by cassini, 10th may 2010.
colour composite; each frame produced from 3 photographs (taken through red, green, and blue filters in sequence). because the moons are moving relative to each other, for each frame a composite must be made for dione (bottom left) and for titan (bottom right), then combined.
