Pelican Nebula as an experimental 3D stereo pair
Images are for two different viewing methods, the first set of images is for the Parallel Vision method and the second set for the Cross Vision method. Viewing instructions can be seen HERE.
NOTE! This is a personal vision about forms and shapes, based on some scientific facts, deduction and an artistic impression. A short explanation, about the method used for the 3D conversion of my astrophoto, at the end of this post.

HOW?
I have been asked many times, how my 3D-images are done, so here it goes!
All the original 2D-images are imaged by me, if not otherwise stated.
Due the huge distances, no real parallax can be imaged for a volumetric information.
I have developed a method to turn any 2D-astronomical image to a various 3D-formats. The result is always an approximation of the reality, based on some known scientific facts, deduction and an artistic impression.
What are the known facts?
By using a scientifically estimated distance of the object, I can organize right amount of stars front and behind the object. (as then we know the absolute position of the object at our Milky-way)
Stars are divided to groups by apparent brightness, that can be used as a draft distance indicator, brighter the closer. There is usually a known star cluster or a star(s) coursing the ionization and they can be placed in right relative position to the nebula itself .
Generally emission nebulae are not lit by the starlight directly but radiation from stars ionizing gases in the nebula. Hence the nebula itself is emitting its own light, at wavelength typical to each element. Due to that, and the thickness of the nebula can be estimated by its brightness, thicker = brighter. Nebulae are also more or less transparent, so we can see "both sides" at the same time.
Many other relative distances can be figured out just carefully studying the image, like dark nebulae must be front of bright ones. The local stellar wind, radiation pressure, from the star cluster, shapes the nebula, For that reason, pillar like formations must point to a cluster. ( Look previous image, above this text.) Same radiation pressure usually forms kind of cavitation, at the nebulosa, around the star cluster, by blowing away all the gas around the source of stellar wind. The ionized oxygen, O-III, emits blueish light, it requires lots of energy to ionize. Due to that, the blue glowing area locates usually near the source of ionization, at the heart of the nebula. This and many other small indicators can be found by carefully studying the image itself.
Using the known data, I can build a kind of skeleton model of the nebula. Then the artistic part is mixed to a scientific part, rest is very much like a sculpting.

WHY?
Firstly, they are great fun to do. Secondly, just because I can.
Many times images of nebulae looks like paintings on the canvas. I like to show a real nature of those distant objects as a three dimensional shapes floating in a three dimensional volume. This is a great way to show, how I personally see astronomical targets as a 3D-forms inside my head.
3D-experiments seems to increase a public interest to a subject, as you might have noticed.
I have studied my astronomical images much deeper, than ever without 3D-modeling.
3D-studies has really added a new dimension to my work as an astronomical photographer. (pun intended)

(You really should get yourself a pair of Red/Cyan eyeglasses! They cost next to nothing and you even can get free ones, if you'll rent a 3D-movie. Anaglyph 3D astronomical images are really cool to look at!)
If you have a Red and Green filters, you can use them! Red goes to Left eye.

3D-images are made by creating artificial parallax to an image. The volumetric models are based on some known scientific facts and an artistic impression.

An experimental 3D-studie, IC 1396 and Sh2-129 in Cepheus
Images are for two different viewing methods, the first is for the Parallel Vision method and the second one for the Cross Vision method. Viewing instructions can be seen HERE.
NOTE! This is a personal vision about forms and shapes, based on some known facts and an artistic impression.

A blog post about this Cepheus mosaic with more images and the technical details HERE
All of my 3D work
Please, have a look in my Portfolio HERE
3D-work will be found under a folder "Volumeric 3D Images"
Animations
If you have troubles to see any free view 3D format, there are several animated images to see HERE
Note. A heavy page, please be patient and let it to load, it'll be worth to wait!
Scroll down for the 3D-animations and click the "Older Posts", at the end of the page, to see more.

A 3D-anaglyph slideshow of my experimental astronomical studies
3D-NOTE!
You'll need Red/Cyan Eyeglasses to be able to see images as 3D.
If you have a Red and Blue filters, you can use them! Red goes to Left eye.

All the original 2D-images are imaged by me.
Due the huge distances, no real parallax can be imaged to form a volumetric information.
I have developed a method to turn any 2D-astronomical image to a various 3D-formats.
Shapes are based on some known facts and an artistic impression.
AN ANAGLYPH 3D-PORTFOLIO
All the images in this slideshow can be found from my portfolio, in large scale.
