Saturn's moons at a common phase angle and a common scale

These photos of Saturn's eight largest moons were taken at different times by the Cassini spacecraft at a variety of different distances but at nearly constant phase angle (lighting direction) of between 43 and 53 degrees. The images have been scaled to represent the correct relative sizes. The moons are: top row: Dione, Mimas, Titan; middle row: Tethys, Rhea; bottom row: Enceladus, Hyperion, Iapetus.
