I'm just blown away by the subtlety of the light in this image - the first frame in Cassini's Helene sequence - image N00172780.
Does anyone know if the light shining at the bottom of the frame is Saturn's limb/terminator, a moon or some other feature? Is the planet part of the background? Also, with an eXtreme contrast stretch (right), Helene's body comes out of the darkness BTW, nice job everyone of the images produced so far. Cassini's own image release is here and the same from JPL here. |

Eyes on the Solar System has predicted trajectory (but not pointing) for this - and looking at the geometry, I think it's the limb of Saturn, The 'darkness' you have, is the night side of Saturn. C/A was well after that and the dark side of Saturn was no longer in the FOV. |
