Unmanned Spaceflight.com _ Uranus and Neptune _ Puck

I have gone back and fiddled with Voyager's lone resolved image of Puck. Phil, do you know if there are any others in which Puck extends more than one pixel? I posted the images on my http://www.strykfoto.org/outericymoons/icymoons.htm Both are larger than the original images (I used my faux-super resolution technique to clarify definition), but the one on the right is enlarged further for easier viewing, although it looks terrible blown up that much.

For comparison, the raw image (cropped from the frame) is shown below, and on the right is the same image, simply stretched, but othewise raw.

Incidentally, this image was lost due to a storm during the original transmission. Fortunately, they got another chance to grab it from the tape recorder before it was overwritten.

Phil, have you had any better luck with this image?

Very nice job, Ted.
This is the best I can do with the "raw" image:

And is not comparable with your image (however, consider that I started from jpeg version posted by you)...
I'm very interested to your "faux-super resolution technique" and eventually you can explain it in the dedicated Image-Processing Forum section (sorry if you already explained and I missed it!).

Sorry, I'm buried right now, but when I can dig out my old stuff I'll post it here. That's going back a way - I probably processed it in IMDISP. Anyone else use IMDISP? It was the first image processing software I ever used.

<grins> I can probably still run imdisp if I boot an old hard drive into dos/win3x

Booting older OS's is becoming harder as technology advances - my home PC will no longer boot the really old stuff that I have (I have at least one DOS 3.x hdd floating about). However If you need to run any seriously legacy (MS) DOS apps that will not run or are unstable\unusable in a modern Windows OS (and I have a couple) then http://dosbox.sourceforge.net/download.php?main=1&begaming_website_session=cd14c3ab180b8d9ed1ee79923c299e3bwill almost certainly run it and it is a lightweight highly portable solution that comes in variants for most current desktop OS's (Windows, OS X, Red Hat Linux, FreeBSD). The http://www.physics.ox.ac.uk/jpc/Demo2.html would be great but it's just a demo for now and can't be used just yet to run arbitrary (private) applications but it is a very cool indication of what can be done and probably will become available before long.

For more heavy duty solutions or if you absolutely must boot an specific older OS and if your primary system is running a recent Windows OS (XP or Vista) then you can also try out http://www.microsoft.com/windows/products/winfamily/virtualpc/default.mspxand mount one of http://www.freedos.org/freedos/files/. Or try the free http://www.vmware.com/download/player/ and a suitable virtual Appliances (e.g. http://www.vmware.com/vmtn/appliances/directory/378 ). A couple of people who play with these things quite a bit have recommended http://www.virtualbox.org/ to me recently which apparently performs better than either of the closed source offerings, is more compatible (e.g. it will mount Solaris 10 without any trouble, something that VPC 2007 finds quite hard to do) and is not limited to running under Windows.

These are my two efforts - done ten years ago now. The smaller one was processed to enhance the possible linear feature which runs across the image from left to right.

Although I know it's a Shakespearian name, "Puck" has to be the most appropriate moniker for a solar system object yet assigned. The thing really does look like a beat-up hockey puck! Maybe we should rename Hyperion 'Sponge'...
