I have been working on a super-resolution view of North Knob from Pathfinder.  It was the second closes topographic feature to the lander, but was obscured by the foreground.  Here is the view that is typically shown of it:
I took super-pan data, and produced this cleaned-up view.

I put this image in another section, but realized it might be more appropriate here
This is my attempt to clean up Robert Leighton's 1956 image of Mars from Mt. Wilson Observatory in 1956. This is, to my knowledge, the best pre-space age groundbased color image of Mars.

Here is an even older view...Mars in 1909 from Lowell.

Ted, is this the original photograph color or did you colorize it?

I think I see one big canal on the far left. rolleyes.gif

Very nice - especially the famous 1956 image - and thanks for sharing.

"After having some business dealings with men, I am occasionally chagrined,
and feel as if I had done some wrong, and it is hard to forget the ugly circumstance.
I see that such intercourse long continued would make one thoroughly prosaic, hard,
and coarse. But the longest intercourse with Nature, though in her rudest moods, does
not thus harden and make coarse. A hard, sensible man whom we liken to a rock is
indeed much harder than a rock. From hard, coarse, insensible men with whom I have
no sympathy, I go to commune with the rocks, whose hearts are comparatively soft."

- Henry David Thoreau, November 15, 1853

In the book, it is a red - green - blue set, and I generated color from that.

Interesting that the red-green-blue set would generate such a nice ochre Mars, just as it looks from a spacecraft. I don't know if it's a function of the limited resolution my childhood telescope (a 3-inch reflector) had, or what, but whenever I looked at Mars through it, Mars always appeared more pinkish than ochre.

Well, to the naked eye it looks light pumpkin-orange -- which seems to be a pretty accurate reflection of its actual color.

To my eye, it looks blood red in a telescope.

I came across a sequence I worked on a while back...I look forward to when Cassini captures something like this...the shadow of the rings on Epimetheus from Voyager. Probably as the solar ring plane crossing approaches, we will start to see things like this.

How about a super-res version of Twin Peaks?
