Actually these stereo pairs are set up for people to go "wall eyed" instead of "cross eyed". You'll see the sphere pop if you're merging at infinity as opposed to crossing your eyes. Dave Bennett On Jun 20, 2009, at 8:41 AM, WAYNE S CLARKE wrote:

Thank you. That crossed eye 3D imaging is great. I had never tried it before.

Once Chuck finally convinced me it really is possible to see 3D using crossed eyes I started looking for stereo pairs to try it with.

I just came across this page from NASA's STEREO mission:

I first tried looking at each pair separately but suddenly found I was seeing all 6 pairs in stereo at the same time. Fun.

This reminded me of my Hale-Bopp stereo pairs. With left and right reversed, it appeared that the comet was behind the stars! When I worked for an aerial surveying company briefly, back in the late '70's, I was exposed to stereo pairs shot from an aircraft. With left and right reversed, the topography was reversed. Stream beds jutted up toward the viewer instead of down into the earth. It's the same with these solar shots. You still get a 3-D effect, but the sun looks like a concave sphere instead of a convex one.
