And this is the de-convoluted image obtained from the image you've posted.

Could this work with the recent HST images of Ceres?

The following pictures are the images of Ceres originally taken by HST (left column) and their de-convoluted images (right column). But please mind those "de-convoluted" images may not be correct but have just exaggerated contrasts, since those pictures' resolutions are low and I've not seen any blurred pictures taken by HST after implementing COSTAR.

Neat!

The left side is the image of Pandora originally taken by Cassini probe and the right side is its de-convoluted image.

I think you may have re-discovered the p-shop unsharp mask algorithm!
Original on left, your image middle, p-shop unsharped original on right.

I didn't know p-shop unsharp mask. I'll check it.
I should have noted the parameters used for de-convolution. The following pictures are (from left:) the original image of Dactyl, de-convoluted image A (focus depth:= 1.8, iteration:= 5), B (focus depth:= 2.2, iteration:= 5), and C (focus depth:= 2.6, iteration:= 5)
Also I attached the image of Janus taken by Cassini probe and its de-convoluted image (focus depth:= 2.2, iteration:= 5)

The problem is that the other than the HST pre-repair Jupiter image and the Tempel 1 image, these images are not out of focus - they are simply limited by pixel size. So while the sharpening is nice, it isn't pulling out any new information.

Quite true. "Deconvolving" obviously bilinearly or bicubically enlarged images has no point. This thing reminds me of a "wonder" procedure some folks applied on low quality encoded mp3 files. They used to decode them into wave audio and then re-code into a much higher bitrate, thinking the quality's going to improve. Then, by the power of auto-suggestion the file really does sound better.
Seriously, though, I believe all that is a result of too many Hollywood movies. How many times have you seen forensics zooming and magically "enhancing" analog or digital images and virtually getting whatever amount of detail it's needed by the plot script...

You can't pull a rabbit out of a hat if you don't have the hat!

Note the bright right edge. This is clearly sharpening, not focusing.

You can clearly see a crater at the upper left corner.

Thank you. The following pictures are the original image of Vesta (left), its de-convoluted image (middle / focus depth:=3.8, iteration:=8) and another de-convoluted image (right / focus depth:=4.3, iteration:=8) The right image is the same as the de-convoluted image in my earlier post.
Also I attached the image of Prometheus and its de-convoluted image (focus depth:=1.8, iteration:=5).
By the way, it is really hard work to find any blurred images among the published images taken by Cassini probe.

"By the way, it is really hard work to find any blurred images among the published images taken by Cassini probe."

You would think that they had the camera set at infinity focus or something!
