Prometheus Makes Contact (natural colors - elab. NASA)

Caption NASA:"The F-Ring shepherd moon Prometheus touches the face of Saturn once more before moving off into blackness and continuing in its orbit.
The F-Ring itself is visible as a thin line just below Prometheus (which is about 102 Km, or approx. 63 miles across).
This view looks toward the unilluminated side of the Rings from about 18° above the Ring-Plane. North on Saturn is up and rotated about 30° to the right.

Images taken using red, green and blue spectral filters were combined to create this natural color view.
The images were obtained by the Cassini spacecraft narrow-angle camera on April 13, 2007 at a distance of approx. 1,7 MKM (such as a little more than 1 MMs) from Prometheus and 1,8 MKM (such about 1,1 MMs) from Saturn.
Image scale is roughly 10 Km (6 miles) per pixel".
