This view looks toward the northern, sunlit side of the rings from just above the ringplane.


The image was taken in visible light with the Cassini spacecraft narrow-angle camera on 27 July 2010. The view was obtained at a distance of approximately 1.3 million km (808,000 miles) from Janus, Prometheus and Atlas. The view was obtained at a distance of approximately 1.2 million km (746,000 miles) from Epimetheus. Image scale is 8 km (5 miles) per pixel on Janus, Prometheus and Atlas. Image scale is 7 km (4 miles) per pixel on Epimetheus.
