Aha! I've been looking for a new rubber-sheeting program for ages. I'm using a geocorrection routine in a GIS. This looks promising as an alternative. Thanks!

Yes - good observation! They look good when enhanced - like Enceladus!

My attempt at stacking images to make the crater (and mound) more visible:

This is as good as I could do resolving them without too much noise. -------------------- |

Comets are like ogres, they have layers.

More on the jets... here I have made the image into a cylindrical projection. The limb would be a horizontal line if the nucleus was spherical. The jets show up nicely. The three long arrows are the three Emily first noted. Two short arrows identify two more. There are signs of small jets between the first three, and a diffuse zone of emission to the right of the other jets. A feature at the left end might be dark-side topography illuminated by light reflected off a nearby sunlit ridge.

Interesting method Phil. The results of the projection are very nice. What plugin / software did you use to produce that?

My image was made by using filter - distort - polar coordinates (polar to rectangular) in Photoshop, after moving the (approximate) center of the disk to the middle of the image. The black parabolas are places where I added space round the original image (image - canvas size) to create space to allow me to center the image.

Wha??? I don't see the latest images in the Comets and Small Bodies gallery of the Planetary Photojournal
Did pull them up using search option for Stardust spacecraft: http://photojournal.jpl.nasa.gov/spacecraft/Stardust -------------------- Some higher resolution images available at my photostream: http://www.flickr.com/photos/31678681@N07/

The link I most commonly use at Photojournal is: http://photojournal.jpl.nasa.gov/new (which you can also get to by clicking on "latest images" at the bottom of the homepage)

My version of enhanced jets, starting from TIFF image and using solarization+gamma+sharpening...
For sure, jets and halo aren't artifact because you can see also the nucleus shadow projected on the gas in the upper part. Thanks to Emily for thie amazing highlight!!! -------------------- I always think before posting! - Marco -
