This image was taken from about 41 degrees above the ringplane, in visible light by the Cassini spacecraft narrow-angle camera on March 10, 2008, when it was at a distance of approximately 1.2 million kilometres away, and at a Sun-Prometheus-spacecraft, or phase, angle of 59 degrees.
This image of Prometheus was taken in visible light with the Cassini spacecraft narrow-angle camera on Nov. 14, 2007, and looks toward the unilluminated side of the rings from about 5 degrees above the ringplane.

Prometheus is seen here pulling a new streamer out of the F ring's inner edge. Trailing behind are previous dark gores that Prometheus has created. The view was obtained at a distance of approximately 1.7 million kilometres from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 67 degrees. Image scale is 10 kilometres per pixel.
This image of the two moons Prometheus and Janus was taken by the Cassini spaceprobe on June 14, 2007, when Prometheus was approximately 1,617,110 kilometres away, and Janus in the foreground was approximately 1,552,444 kilometres away

This image of Prometheus and Saturn's F ring, was taken in visible light with the Cassini spacecraft narrow-angle camera on April 18, 2007 at a distance of approximately 2 million kilometres from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 87 degrees.

Prometheus approaches closely to the F ring once during each circuit around Saturn, disturbing the orbits of the small particles in the ring and creating a streamer of material that then shears out, following the moon as it speeds off. This view looks toward the unilluminated side of the rings from about 37 degrees above the ringplane. Prometheus is brightly lit by the Sun on one side and lit more modestly by Saturn's reflected light on the other side. The image scale is 12 kilometres per pixel.
Prometheus speeds ahead of two dark gores in the F ring's inner edge. The ring's bright core swerves and twirls in its wake. Prometheus is partly lit, at right, by reflected light from Saturn. This view looks toward the unilluminated side of the rings from about 54 degrees above the ringplane.

The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 17, 2007 at a distance of approximately 1.8 million kilometres from Prometheus and at a Sun-Prometheus-spacecraft, or phase, angle of 107 degrees. Image scale is 11 kilometres per pixel.
In this image Prometheus draws material from the F ring. Near the lower left is similar feature the moon created on a previous pass near the ring.

Prometheus (102 kilometres across) is overexposed in this image. This view looks toward the unlit side of the rings from about 41 degrees above the ringplane. The image was taken in visible light with the Cassini spacecraft narrow-angle camera on March 14, 2007 at a distance of approximately 1.8 million kilometres from Prometheus. Image scale is 11 kilometres per pixel.
