An image taken by Brian Hamilton on Facebook shows Saturn’s flattening at the polar extremes. The flattening as seen sidelong is a prelude to the inwards sloping of the opening to the inner world, which can be thought of as an hourglass-like.
The image can be currently found, and not very far down the Discussion list, on the following Facebook page: Maksutov & Schmidt-Cassegrain Telescope Owners Realm Use the Facebook search function.
Brian Hamilton also has it up on his personal Facebook page: Brian Hamilton | Facebook
And many other planetary images.
Cheers!
