Sh2-11 as an animated 3D
Animations are made by creating artificial parallax to an image. Then two images are animated together by using conversion web service, Start3D. There can be some artifacts in images, due the experimental nature of this work! The volumetric models are based on some known facts and an artistic impression.
Please, let the images load for few seconds to see them animated!

This composition is very close to a visual spectrum.
NGC 6357 locates in constellation Scorpius and it's know by names Sharpless 11, RCW 131 and Gum 66.
Looks very much like an Egyptian Horus!

A Starless version to show the actual nebulous.
In my processing technique, the starless image is used as a color map for HST-palette balancing.
Now and then I publish an image with a suppressed stars, since it can look kind of nice/spooky.

M17, the "Omega nebula"
M17, imaged with the Northern Galactic members remote telescope in Australia.
The Omega Nebula, also known as the Swan Nebula or the Horseshoe Nebula, cataloged as Messier 17 and NGC 6618. This H-II region loactes in constellation Sagittarius. Distance from Earth is between 5000-6000 light years and it spans about 15 light years in diameter. Image area is 30'x30', about half a degree.
Open cluster of 35 hot young stars lies inside of the nebula and causes ionization glow of the elements.

Helix nebula with some new photons added
Litle by litle the image gets deeper when more exposures gets added.
Previous version here:
The Helix nebula, NGC 7293. Planetary nebula in constellation Aquarius about 700 light years from the Earth..
(The helix has been often referred to as the "Eye of Good",
I'll like to know, which one it's supposed to belong... least we know now He/She has very large Blue eye(s).)
This is a start for an imaging project, since the Helix has lowish surface brightness, it'll need a long integration time. Now there is just One hour used for the Luminance channel and 10 min./each RGB-channel.
I think, about Five to ten hours is needed to reveal dimmer outer parts of this Planetary nebula.
Later we'll shoot all the narrow band channels, H-a, O-III and S-II, too.

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.
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. The result is always approximation of the reality, based on some known facts 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 an object at our Milky-way)
There usually is a known star cluster or a star(s) coursing the ionization and stars can be placed in right relative position to the nebula itself .
Stars are divided to groups by apparent brightness, that can be used as a draft distance indicator, brighter the closer.
The nebula itself is emitting its own light, when ionized, typical to each element.
The thickness of the nebula can be estimated by its brightness.
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 nebulae, pillar like formations must then point to a cluster for that reason.
Same radiation pressure usually forms kind of cavitation hole at the nebulosa, around the star cluster, by blowing away all the gas around it.
Same radiation pressure usually forms kind of cavitation hole at the nebulosa, around the star cluster, by blowing away all the gas around it.
Many other small indicators can be found from the image itself.
The artistic part is then mixed to a scientific part, rest is very much like a sculpting.
I have published a, little simplified, step by step tutorial about turning astronomical images to a 3D-stereo pairs under a PhotoShop. It can be found from here as a PDF: astroanarchy.blogspot.com/2009/04/neaic.html
WHY?
Firstly, they are great fun to do. Secondly, because I can.
3D-experiments seems to increase a public interest to a subject, as you might have noticed.
Personally, I have studied my astronomical images much deeper, than ever without 3D-modeling.
The 3D-studies have really add a new dimension to my hobby as an astronomical photographer. (pun intended)
