Crossing the Rings...

Original caption:"Prometheus has just passed - and gravitationally disturbed - some of the fine particulate material in the F-Ring, creating the sheared gap visible in the inner strands of the Ring. This view looks down from about 10° above the ringplane. Prometheus and the Rings are sunlit from below. At lower right lies the outermost part of the A-Ring, which grows suddenly brighter outside of the 42-Km-wide (such as about 26-miles) Keeler Gap.
The image was taken in visible green light with the Cassini spacecraft narrow-angle camera on Aug. 2, 2005, at a distance of approximately 632.000 Km (approx. 392.000 miles) from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 122°. Image scale is 4 Km (about 2 miles) per pixel".
