A combined image of EIT 195 and 204 to produce a subtly coloured 3D solar image from 2 different wave-lengths. This is true stereo, not a derivation. Stereo parallax comes from rotation of the sun itself during 6 hours.

A request has been received from Wojtek Rychlik to show the sun with a 12 hour parallax in the hopes of it looking more spherical. This next image shows that.
Zero parallax has been moved behind the screen surface because the front of the sun projected too far forward and made it hard to view using this increased "stereo base." Now you can decide which you prefer. One of the problems with a 12 hour parallax is: more things can happen on the sun in 12 hours than in 6 hours, so spoiling the stereo effect. At the moment the sun is relatively quiet which may have helped here. As it is some false stereo has crept in (at least I think it is false). We sure look forward to the STEREO satellite pair. The different colour is caused by a different method used to combine the wavelengths and then correct for anaglyph ghosts and retinal rivalry - see my anaglyph page if this is unintelligible to you.

Now compare the two images by clicking on the top corner of each. You will see what happens to the sun after 4 days and get a good idea of how it rotates. You can also decide if you prefer double parallax, or not.
