Hi folks,

to be honest, I do not know what Pandora is in this image. Is it the bright knot in the rings? Or is it the huge dark rock in the upper right corner?
Cause Fraser says in his report:
"Pandora is 84 kilometers (52 miles) across.............when Cassini was approximately 610,000 kilometers (379,000 miles) from Pandora."
Does Cassini have such an enormous Zoom to get Pandora this big in the image, or is it something competely different?
