Here's a great image that would make a breathtaking stereograph, today's APOD (August 3):

care to delight us again, Harry?

Ok. The following stereograph was synthesized from the part of the picture you've mentioned.

Thank you so much Harry! I knew it would look awesome. Do you have a program that makes these, or is it as easy as cropping and copying the right sizes/distances in MS paint?

Yes, I have the software for synthesizing stereograph from single photo image. The algorithm used for synthesizing that stereograph is simple (the source code is company confidential, though!) and it is explained in the following website.

It sounds fantastic, doesn't it? Please show us your pictures made by Photoshop.
The following picture is Dione deconvoluted by the software "Focus Corrector". For other examples made by Focus Corrector, please visit;

Very cool, Harry. Thanks.

A thing about stereo space images is that, in fact, we donīt have a natural paralax; The background of space will always be flat, as far as the human perception is concerned. Thus, a 3D space image is always a construct, a simulation. We wouldnīt have a 3d view, even if we were close to the Nebula.

Probably. We can not distinguish the difference of distances between Mars - earth and Polaris - earth by just viewing them. However we can distinguish high clouds from low clouds because lower clouds are more blurred. So at least in the case of nebulae, they may be seen perspectively when we pass in the vicinity to them.

I´m affraid they may not. The whole thing boils down to the angular separation of our eyes. In order to view a nebula in perspective you need a base line spanning a couple of light-years. The universe gets flat beyond 20 miles.

You may think measuring the deviation from focal point is meaningless for astronomical objects since their focal length from telescope is regarded as infinity. However as shown in the following stereographs of clouds on earth synthesized by Stereographer (please view them with parallel eyes or crossed eyes which you prefer), we can see those clouds perspectively even though their focal length is almost infinity for our eyes. Namely our eyes are thought to recognize 3-dimensional feature of object without perceiving the difference of geometrical focal length.
