First of all, again the two existing encounter animations:
Animation 1
Animation 2

Nearest approach:

Resolution about 3,6 km/pxl.

And some pre-info about upcoming encounters:
2006 Mar 25 to Apr 18: Apr 11 - 602.412 km; 14-3.6 km/pxl; medium to high phase, southern hemisphere as crescent
2006 Jun 17 to 27: Jun 23 - 1.343.000 km; 14-8.1 km/pxl; medium to low phase, sub-Saturn hemisphere
2006 Sep 08 to 09: Sep 02 - 1.816.000 km; ~20 km/pxl; zero phase (3 to 0.05 deg), sub-Saturn
2006 Nov 26: 1.997.000 km; 12 km/pxl; very low phase, sub-Saturn
2007 Feb 12 to 15: Feb 14 - 2.249.000 km; ~14 km/pxl; sub-Saturn; very low phase and eclipse
2007 Apr 14: 2.256.000 km
2007 Jun 22: 1.817.000 km; ~14 km/pxl; med. phase, trailing side
2007 Sep 03 to 09: 8.6-0.7 km/pxl; very high phase, western Cassini Regio
2007 Sep 10: 480-10-540 m/pxl; targeted flyby, trailing side
2007 Sep 11 to 17: 0.7-7.1 km/pxl; low phase (~33 deg) trailing side
2007 Sep 27: 15 km/pxl, low phase sub-Saturn+trailing side
2007 Nov 26: 1.371.000 km; 8.2 km/pxl; very high phase, north pole, possibly graylight
2008 Feb 13: 2.045.000 km; 14 km/pxl; high phase, north pole, possibly graylight

Days around Sep 10 belong to the targeted fly-by in about 1000 km distance,
others will only be some OPNAVs.

Bye.

Many thanks for the advices on converting the Iapetus-map from 0° to 180° center.
I will try when time allows...

Back to Iapetus...
...I found these two 'old' Cassini images back from July 19, 2004:

Attached Image

Distance: ~ 2.9 Mio. km
Resolution: 17 km/pxl

A first hint on what we'll see in the upcoming far-encounter.
Visible is the bright southern rim of the big bassin in eastern CR
and the polar region with a large amount of craters below.
Actually what is the dark curved structure parallel to the terminator?
The eastern rim of another big bassin?
There also seems to be a greater structure - possibly a crater - left to the terminator south of this dark bow.

Bye.

Yes...that is a sequence from slightly farther out than the one I used to make this super-res view I posted a while back.
