Here you can watch various nebulae stereoscopically!

Yes, but it is fake stereo, not based on real data.

Indeed, if I understand your site correctly, you intend the pictures to
be viewed with divergent viewing. Yet if you do that with these nebula
pictures, the background stars appear in front of the nebulae,
presumably because they are brighter. They looked more reasonable to me
with convergent (cross-eyed) viewing.

At any rate, you really should make it clear at the top of the page that
the depth portrayed in these stereo images has nothing to do with actual
depth of the objects involved, but relates only to their brightness.

...the background stars appear in front of the nebulae...

Oh, really? If available, could you indicate such star(s)? I also have
felt strange that some stars appear in front of nebulae in my pictures.
By the way my method is NOT based on the brightness of object, but the
dimness of object. For detail of that method, please visit,

to security check program imposed on Internet Explore users...)

Er, all of them, depending on whether you view them convergent or
divergent (your page didn't specify which was correct).

Yes, these are the same thing (but in my mind it's more proper to refer
to this scale as a brightness scale).

That's correct -- I am using a Mac, and I couldn't view your page very
well, though I was able to work around it enough to get the general idea.

And please don't misunderstand -- I think your technique is very clever,
and the resulting pictures are beautiful. But when I first saw them, I
thought I was looking at true stereo -- perhaps of nearby nebulae,
photographed 6 months apart. You should make it clear at the top of the
page that this is not the case.

Best,

Thank you for your comment. You suggested as,

... You should make it clear at the top of the
page that this is not the case.

for the reason as,

...all of them (should be behind the nebulae.)

However some stars are actually in front of nebulae. Therefore I could
not follow your suggestion.
