Bubble 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)

A method used for the 3D conversion, a short explanation

All pillar like formations are pointing to a source of ionization, the open cluster NGC 7822. There are some more dense areas in a gas, able to resist the radiation pressure from young star cluster. Those dense areas, 
at a tip of the pillars, are also potential places for the formations of the new stars.

About the structure of the nebula

All pillar like formations are pointing to a source of ionization, the open cluster NGC 281. There are some more dense areas in a gas, able to resist the radiation pressure from young star cluster. Those dense areas, at a tip of the each pillar, are also potential places for the formations of the new stars. Note. There are some very dim outer formations in this nebula, I haven't noticed them before. Like the one pillar like at the eleven o'clock position.

Original blog post about this photo can be seen HERE

INFO

Just next to Sh2-221 locates a closest known planetary nebula, Sh2-216. This is also a very rarely images target, due to its low surface brightness and large angular dimension. This mosaic image covers over seven degrees of sky vertically. (The Moon has an apparent dimension of 0.5 degrees.)  Mosaic is made out of my new data of Sh2-221 and an older material of Sh2-216. Some new exposures was taken for the Sh2-216 to match the background for a mosaic image. 

Image shows two different ways to end a life of the star. At left, as a Supernova and at right as a Planetary Nebula. (Massive stars will go to a Supernova, after burning out all of the Hydrogen. There will be a Neutron star or a Black Hole left behind. Lighter stars, as our Sun, will turn to a Planetary Nebula, after ran out of Hydrogen. There is a core of the star left behind, it's called a White Dwarf  and it will cool down gradually. )
