Bright "things" in the Sky of Saturn

Caption NASA:"Saturn's shadow cloaks the faint D-Ring at the bottom of this image. Observations of the shadow boundary, like this one, enable scientists to clearly detect and measure the brightness of diffuse and faint Ring features like the inner part of the D-Ring. Such brightness measurements are often difficult to make, but the shadow region provides a very dark standard against which to compare the D-Ring, as the only brightness in the shadow is provided by the background of space.
The bright specks across the scene, both in the bright Rings and in the shadow, are either stars or cosmic ray hits on the camera's detector. This view looks toward the unlit side of the rings from about 42° above the Ring-Plane.

The image was taken in visible light with the Cassini spacecraft wide-angle camera on Nov. 12, 2006. Cassini was then at a distance of approx. 1,4 MKM (about 900.000 miles) from Saturn and at a phase angle of 152°.
Image scale is roughly 8 Km (5 miles) per pixel".
