Images from the wide angle camera are nearly filing the frame again:

Yes, these Saturn images are getting great and much better than anything from Voyager. I'm surprised there have been no spectacular false color closeups at the Cassini website - in addition to looking spectacular they show varying amounts of clouds and different cloud heights so they are not meaningless works of art.

However, the Iapetus images are extremely frustrating. Something is wrong with the pointing so Iapetus is outside the field of view in almost all of the images. And these are images that would have been a bit better than the best Voyager 2 images. Hopefully this can be fixed in time.

Also the automatic contrast stretch applied to the images as displayed at the Cassini website makes things even more frustrating since it almost completely ruins the images where Iapetus is visible. Things are probably not going to get really fun until the PDS files get released next summer.

Yikes........you're right, it looks like something went wrong with the pointing during the Iapetus observations.

Only a couple of fairly decent pics of it

Maybe the next batch of RAW images might give us a better look at Iapetus

Yep, a much better view of Iapetus

....latest batch look worse.

In the last observation ( oct 17th ) Cassini apparently just managed to keep Iapetus in frame:

Hopefully this pointing error will be fixed before the Titan flyby... Or is it maybe just a matter of Iapetus' location that is not known accurately enough?

It's the later - these observations will allow them to tighten up the orbital params for Iap. so it should happen in the future

This encounter also would give us a better mass estimate for Iapetus. Because of our current uncertainty, the Iapetus distant encounter distance on December 30 had to be raised to ensure that Huygens doesn't pass to close to Iapetus.
