Help understanding this unsettling image of Titan, Epimetheus, and Saturn's rings?
This NASA page says this photo was taken on April 28 2006.

Using Celestia, I managed to find the picture from Cassini that best lines up with the photo. It doesn't match up precisely, but that's to be expected as the calculated orbital elements of all these moons (and cassini) in the software won't necessarily match up to reality precisely.


Below is the zoomed out version of this shot. You can see Titan in the centre and Epimetheus as a dot on top.

And here is the top down shot from Cassini to the moons. Circled are Epimetheus and Titan.


So to answer your question: Titan is really big compared to epimetheus (about 50x), Titan has an atmosphere and so appears fuzzy (It is actually in focus, everything in space is very far away and so is effectively at infinity for focusing purposes), and the rings are highly oblique, so you only see a small slice of them.
