Tomorrow - best view yet, less than 50,000 km. I hope we get a view of a different part of the surface than we've seen before.

Cassini's recent view of Helene was the subject of a nice release today:
http://saturn.jpl.nasa.gov/multimedia/imag...fm?imageID=2273 Here I've stretched the Saturnshine areas even more to pull out everything that might be visible. It really shows the value of even high phase imaging of these little things. Phil

It's possible the PDS release will allow even more to be visible as the brightness was clipped here to 8 bits from 12 bit data. -------------------- |

From the two images stretched to show features in sunlight perhaps, but these images weren't exposed to show a great amount of detail in Saturn-shine, and I don't think there is much there beyond what is in the right-most image. -------------------- &@^^!% Jim!

Reviving an old thread... The Helene pics recently hit the PDS so I had a whack at them. Below's a RGB composite and a very brightened up view showing yellow saturnshine faintly illuminating the moon's dark side.
Compare this to what Phil managed to pull out from the badly artifacted raws. The green ghost image is likely an internal reflection in the filter somewhere, I've seen it in other images when massively brightened. Magnified 2x. Lastly, here's a simple attempt to join the two (don't laugh):
