First High-Quality Real Stereo Image of Pluto
We're going to try to spot Pluto with the Grim at Saturday's star party. Somehow I don't think it will look this good. :) patrick First High-Quality Real Stereo Image of Pluto http://epod.usra.edu/blog/2015/07/first-high-quality-real-stereo-image-of-pl...
That's awesome Patrick, thanks. I wonder if methane ice is sort of soft or mushy so that heavier objects would slowly sink into it. A peak in the middle of a create looks as if it has subsided, leaving smooth material inside the crater. If the surface were relatively soft that might explaining blurring and disappearance of features.
That was supposed to be crater, not crate.

I was able to merge the pictures. Interesting perspective. On Thu, Jul 23, 2015 at 12:59 PM, Wiggins Patrick <paw@digis.net> wrote:

The full moon shouldn't affect it much, it is starlike in the eyepiece, not a diffuse object. I'm confident that it will be easy in the Grim. 32 inches is a lot of telescope. The hardest part will be picking it out of the surrounding star field. Have a good finder chart printed-out for use at the telescope. On 7/23/15, Patrick <paw@digis.net> wrote:

For those who prefer the cross-eyed method of viewing, here's how on your computer running Windows 7 or above. Use the Windows Snipping tool to outline (snip) the right-hand image of the pair displayed by NASA. Do not include any white area in your outline. Place the resulting snipped image window to the left of the left-hand image of the NASA pair. Line up the snipped image vertically just as the NASA images are aligned with each other. Narrow the snipped image window so Pluto is closer to the right boundary of the window, but without clipping off any of Pluto's image. Slide the snipped image window as close to the left side of the NASA pair as possible without overlapping any of the left-hand NASA image. Cross your eyes and concentrate on the two images on the left out of the three that are now showing on the screen. Ignore the image on the far right of the NASA pair.

Maybe I'm missing something but with my Mac I just look crossed eyed at the images the way they are displayed. No need to make any adjustments. Does Windows make that not work? patrick On 23 Jul 2015, at 13:59, Ed <utnatsedj1@xmission.com> wrote:

This appears in proper (but not good) stereo when seen with the relaxed eyes method, not the crossed eyes method. It's not good stereo because it's exaggerated, making Pluto's shape look like a watermelon and not the cantaloup shape it really has.

The EPOD stereo pair is not for the crossed-eyes method. You can fuse the images with crossed eyes, but the relief will be reversed. For those who can't perform the image swap that Ed kindly posted, here is a link to a pair that I reversed, for using the crossed-eyes method: http://i260.photobucket.com/albums/ii24/JethroTull1958/Pluto%20Stereo%202_zp... Remember that for the "free-fusing" method to work, the center of each image can't exceed your interpupilary distance. But the crossed-eye method works for any size pair, and you need not cross your eyes more than you normally would if you were looking at something about a foot in front of your face. Just back away from your monitor if you feel you are forcing it. It shouldn't cause any discomfort. One of the image pairs is much lower resolution than the other, which detracts from the effect. Another thing to remember is what's called the "scale model effect". For images like these to appear 3-D, the pair must be taken at a separation much, much greater than a person's interpupilary distance. It makes the object look much smaller than it would in reality, if you were really that close, while at the same time, accentuating the topographical relief. Still, it's a neat image pair. We now have a mental image of Pluto to think of when contemplating it, instead of just that star-like speck we've seen in the eyepiece.
Chuck, Very good explanation. Thanks for that post and the posted pair. Too bad the EPOD editor doesn't see fit to post them as sets of 3 images, left two for cross-eyed viewing and right two for parallel line-of-sight viewing, then everyone can take their pick, and enjoy the 3D experience. BTW, I think when we mention cross-eyed viewing it puts people off because they think they "can't cross their eyes" as children often do. For stereo viewing we are talking about "crossing one's eyes" no more than when we read a book, which everyone with normal vision does.

EPOD looked like a bowl to me. Your version looks like a sphere. Well done. patrick On 23 Jul 2015, at 20:54, Chuck Hards <chuck.hards@gmail.com> wrote:

Patrick, Now that Chuck has posted a cross-eyed pair of Pluto images, compare your cross-eyed view of the NASA images with the same view of those that Chuck posted. If you don't see an astounding and obvious difference, then you are not using the same viewing technique with those two pairs of images. And, no, stereo viewing has nothing to do with Mac or Windows.
