Saturn's limb (NASA - natural colors)

Caption NASA originale:"From its unique perspective high above the Planet, the Cassini spacecraft looks down upon Saturn's murky Northern Hemisphere. The bluish hues seen in some Cassini views of Saturn's North are notably absent in this viewing geometry.
The dark side of Saturn's extensive Rings is just visible in the top half of the image.
The view looks toward the unlit side of the Rings, from about 44° above the Ring-Plane.
Images taken using red, green and blue spectral filters were combined to create this natural color view.

The images was taken with the Cassini spacecraft wide-angle camera on Oct. 30, 2006, at a distance of approx. 1,4 MKM (about 900.000 miles) from Saturn and at a Sun-Saturn-spacecraft, or phase, angle of 150°. Image scale is roughly 78 Km (about 49 miles) per pixel".
