Stereoscopic M17 (view: parallel/crossed eyes) synthesized by Stereographer.

The trial version of Stereographer has been updated. It can make stereographs for both parallel/crossed eyes viewers no matter whether the focal point is in the foreground or background.

Fortunately I could get Mr. R. Croman's permission (Thank you, Russ!) The attached stereographs (view: parallel/crossed eyes) are based on his photo (http://www.rc-astro.com). Do you feel those stereographs too big to see stereoscopically? Then please visit here. You'll see the same (parallel) stereograph through smaller two windows and probably it will be easier to see it stereoscopically.

Thanks for posting all these beautiful images, Harry.
(My request is always the same: pls, could you make larger stereograms and, possibly, crossed/anaglyph version as you did in the past?)

However don't you feel hard to see too large stereograph? At least when the size of original picture is more than half of the screen, we'll not able to see the synthesized stereograph by parallel/crossed eyes.

I've omitted the stereographs for crossed eyes for saving the space in the server You can easily make the stereograph for crossed eyes from that for parallel eyes by exchanging the left and right images on that stereograph (actually some of stereographs for crossed eyes I've ever posted were made from such exchange by "cut and paste"!)

The following stereographs are for Lagoon Nebula (detail) synthesized by Stereographer (view: parallel/crossed eyes). The original image was taken by HST.

Harry, you aren't able to visualize large stereograph only if you're using parallele eyes... In fact, with this technique, distance between images centers cannot exceed intra-ocular distance (6-7 cm)! With crossed-eyes, on the other hand, you can fill your monitor and still visualize them; yes, larger the images, less confortable and more close they appear but... I trained my eyes to see very large stereograms on my 17" monitor and I really enjoy them! Try these two, isn't impossible!



I know that I can easily make the crossed eyes version with a simple "cut and paste" (and, in fact, I already did for most of your images!). However, cannot appreciate magnificent details because they are small!
The alternative way, visible to a wider public, is to make stereograms, but colors are altered... This is another example made from one of your biggest published stereographs:

Oh, thank you for those "genuine" stereographs. Was the picture of right side taken by you? It's amazing stereograph. Although I've tried to synthesize stereographs based on those pictures, I could not get sufficient results... Is the another picture for Keyhole Nebula an anaglyph? (I could not see it stereoscopically, though.) Regarding crossed-eyes stereographs, please refer to the message I've sent in your message box.

Harry, image on the right is mine (happy you like it, I have dozen like this!)...
About Keyhole Nebula, good catch! I must admit my mistake, I used same image for left and right eye and I didn't make a double check (with coulored glasses, seems to see some 3D features one the left but probably is only a color-related spurious effect... this is the reason I don't like analglyphs!).
I apologize and now I post the true anaglyph:

Oh, this time I can see it just stereoscopically. It's wonderful.


I agree with you. Moreover since the original image is filtered through blue or red film, the harmony of colors may be spoilt. Nevertheless the anaglyph you've posted is impressive.
