Unveiling The Veiled

The Veil nebula supernova remnant in Cygnus. Original image was shot with the Canon EF 200 mm f1.8 camera optics full open, QHY9 astro camera and Baader narrowband filters at 2013.

New data is shot with Tokina 300mm f2.8 camera optics and Celestron Edge HD 11" telescope, Apogee Alta U16 astro camera with Astrodon narrowband filters between 2016 - 2020
Total exposure time is now about 45 hours.

3D-study of Veil Nebula Photo


Every single pixel in this 3d-animation is from the original 2D-image above. The model is based on on known scientific facts, deduction and some artistic creativity. The result is an appraised simulation of reality. Astronomical photos are showing objects as paintings on a canvas, totally flat. In reality, they are three dimensional forms floating in three dimensional space. The purpose of my 3d-experiments is to show that and Give an idea, how those distant objects might look in reality.

INFO


Since all of the heavier elements are born in exploding stars, we all are children of supernovae. Veil Nebula is located in the constellation Cygnus at a distance of 1500 light-years. It spans three degrees of sky, (Moon has an angular diameter of 0,5 degrees at the sky) real diameter is around 70 light-years. I collected data for the photo between 2012-2020 and I made this 3D model in 2021,exposure time is 45 hours

How the 3D-model is made


My Moleskine notebook pages from 2008, I planned how to convert nebulae to 3D


For as long as I have captured images of celestial objects, I have always seen hem three-dimensionally in my head. The scientific information makes my inner visions much more accurate, and the 3-D technique I have developed enables me to share those beautiful visions with others.

How accurate my 3-D-visions are depending on how much information I have and how well I implement it.

The final 3-D-image is always an appraised simulation of reality based on known scientific facts, deduction, and some artistic creativity.

After I have collected all the necessary scientific information about my target, I start my 3-D conversion from stars. Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to know its absolute location since we know its relative location. Stars ionizing the nebula have to be very close to the nebula structure itself. I usually divide up the rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available, I use them, but most of the time my rule of thumb is sufficient. By using a scientific estimate of the distance of the Milky Way object, I can locate the correct number of stars in front of it and behind it.

Emission nebulae are not lit up directly by starlight; they are usually way too large for that. Rather, stellar radiation ionizes elements within the gas cloud and the nebula itself is glowing light, the principle is very much the same as in fluorescent tubes. The thickness of the nebula can be estimated from its brightness, since the whole volume of gas is glowing, brighter means thicker.

By this means, forms of the nebula can be turned to a real 3-D shape. Nebulae are also more or less transparent, so we can see both sides of it at the same time, and this makes model-making a little easier since not much is hidden.

The local stellar wind, from the star cluster inside the nebula, shapes the nebula by blowing away the gas around the star cluster. The stellar wind usually forms a kind of cavity in the nebulosity. The same stellar wind also initiates the further collapse of the gas cloud and the birth of the second generation of stars in the nebula. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.

Ionized oxygen (O-III) glows with a bluish light, and since oxygen needs a lot of energy to ionize it, this can only be achieved relatively close to the star cluster in the nebula. I use this information to position the O-III area (the bluish glow) at the correct distance relative to the heart of the nebula.

Many other small indicators can be found by carefully studying the image itself. For example, if there is a dark nebula in the image, it must be located in front of the emission one, otherwise we couldn’t see it at all.

Using the known data in this way I build a kind of skeleton model of the nebula. Then the artistic part is mixed with the scientific and logical elements, and after that the rest is very much like creating a sculpture on a cosmic scale

Three 3D-conversions out of my astronomical photos

 I have made dozens of 3D-conversions out of my astronomical photos. As an artist I like to find a new views to the reality. My models are not just a guesswork, the conversion is based on real scientific data.
At the end of this blog post there is a short explanation, how I do my conversion work.

Viral Nebula Rocks

IC1396 converted to 3D animation, very first of its kind
NOW on SuperRare

I turned my photo of IC1396 to a 3d-model at 2012 to show that it’s actually a three-dimensional volume floating in three-dimensional space. This artwork is not just a guess work, it’s based on scientific data about the structure of emission nebulae and real distance information. 

This animation went viral and it was published by several news media and major websites globally at 2012, links after the photos


Location, Constellation Cepheus at distance of about 3000 light years
IC 1396 spans about three degrees of sky (Full Moon has diameter of 0,5 degrees)
I took the photo and made the model at 2012, exposure time 15 hours. 
Time used for the collecting scientific data, 3D-model and animation way too much.

Visions of Veil

 This is an experimental test with a 3D-conversion of my astronomical image. Only real elements from the original image are used, there is nothing added but the estimated volumetric information!

NOTE. This is a personal vision about shapes and volumes, based on some scientific data, deduction and an artistic impression.

How is the volume added to my photos?

Importantly, for as long as I have captured images of celestial objects, I have always seen them in three dimensions in the theatre of my mind. I did develop a unique process to create scientifically accurate 3D volumetric images of 'my' nebulas. The final 3D volumetric image is always an appraised simulation of reality based on known scientific data, deduction, and some artistic creativity.

After I have collected all the necessary scientific information about my target, I start my 3-D conversion using the stars in the image. Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to know its absolute location since we know its relative location. Stars ionizing the nebula have to be very close to the nebula structure itself. I usually divide up the rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available, I use them, but most of the time my rule of thumb is sufficient.

Emission nebulae are not lit up directly by starlight; they are usually way too large for that. Rather, stellar radiation ionizes elements within the gas cloud. So, it’s the nebula itself that is glowing. (The principle is very much the same as in fluorescent tubes.) The thickness of the nebula can be estimated from its brightness, since the whole volume of gas is glowing, brighter means thicker. Nebulae are also more or less transparent, so we can see both sides of it at the same time, and this makes model-making a little easier since not much is hidden.

The local stellar wind, from the star cluster inside the nebula, shapes the nebula by blowing away the gas around the star cluster. The stellar wind usually forms a kind of cavity in the nebulosity. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.

Oxygen needs a lot energy to ionize it, this can only be achieved relatively close to the star cluster in the nebula. I use this information to position the O-III area (the bluish glow) at the correct distance relative to the heart of the nebula.

Many other small indicators can be found by carefully studying the image itself. For example, if there is a dark nebula in the image, it must be located in front of the emission nebula, otherwise we can’t see it.

Explosions in space are more or less symmetrical, due to that, most of the supernova remnants and planetary nebulae mainly has a ball like appearance.

Using the known data in this way I build a kind of skeleton model of the nebula. Then the artistic part is mixed with the scientific and logical elements, and after that the rest is very much like creating a sculpture on a cosmic scale.

4D video of the Veil Nebula SNR


The weather up here 65N has been cloudy for months. I played with my older images and made couple of  experimental 3D animations out of them. Here is the first one, the Veil Nebula SNR in Cygnus. This is actually a 4D animation since it shows the time too... I made this just for fun, this is not an accurate model of reality but close enough for me.

Info about the technique used

Due to huge distances, real parallax can't be imaged in most of the astronomical objects.
I have developed an experimental technique to convert my astropics to a artificial volumetric models.

My 3-D experiments are a mixture of science and an artistic impression. I collect distance and other information before I do my 3-D conversion. Usually there are known stars, coursing the ionization, so I can place them at right relative distance. If I know a distance to the nebula, I can fine tune distances of the stars so, that right amount of stars are front and behind of the object.

I use a “rule of thumb” method for stars: brighter is closer, but if a real distance is known, I'm using that. Many 3-D shapes can be figured out just by looking carefully the structures in nebula, such as dark nebulae must be at front of the emission nebulae in order to show up etc...

The general structure of many star forming regions is very same, there is a group of young stars, as an open cluster inside of the nebula. The stellar wind from the stars is then blowing the gas away around the cluster and forming a kind of cavitation – or a hole — around it. The pillar-like formations in the nebula must point to a source of stellar wind, for the same reason.

How accurate the final model is, depends how much I have known and guessed right. The motivation to make those 3-D-studies is just to show, that objects in the images are not like paintings on the canvas but really three dimensional objects floating in the three dimensional space. This generally adds a new dimension to my hobby as an astronomical imager.

A study about the general structure of the IC 410

All pillar like formations are pointing to a source of ionization, the open cluster NGC 1893 at the heart of the IC 410. There are some more dense areas in a gas, able to resist the radiation pressure from young star cluster. Those dense areas, at tip of the pillars, are also potential places for the formations of the new stars. A radiation pressure (solar wind) from the cluster NGC 1893 is forming a hollow space inside a gas cloud, it  can be seen in my 3D-studies too.

Info about the technique used

For as long as I have captured images of celestial objects, I have always seen
them three-dimensionally in my head. Over time I realized that we actually have
enough scientific information to build a coarse skeleton model of the nebula itself.

The scientific information makes my visions much more accurate, and the 3-D technique I have developed enables me to share those beautiful visions with others.
How accurate my 3-D-visions are depends on how much accurate information I have and how well I implement it.

Also, many different estimates are needed for the 3-D model. The final 3-D-image is always an appraised simulation of reality based on known scientific facts, deduction, and some artistic creativity
on top of everything else.

After I have collected all the necessary scientific information about my target,
I start my 3-D conversion using the stars in the image. Usually there is a recognizable star cluster which is responsible for ionizing the nebula. We don’t need to
know its absolute location since we know its relative location. Stars ionizing the
nebula have to be very close to the nebula structure itself. I usually divide up the
rest of the stars by their apparent brightness, which can then be used as an indicator of their distances, brighter being closer. If true star distances are available
I use them, but most of the time my rule of thumb is sufficient.
By using a scientific estimate of the distance of the Milky Way object, I can
then locate the correct number of stars in front of it and behind it.

Emission nebulae are not lit up directly by starlight; they are usually way too
large for that. Rather, stellar radiation ionizes elements within the gas cloud. So it
is the nebula itself that is glowing, at the characteristic wavelengths of each ionized element. (The principle is very much the same as in fluorescent tubes.) I use
this information for my 3-D model. The thickness of the nebula can be estimated
from its brightness, since the whole volume of gas is glowing, brighter means
thicker. By this means, forms of the nebula can be turned to a real 3-D shape.
Nebulae are also more or less transparent, so we can see both sides of it at the
same time, and this makes model-making a little easier since not much is hidden.

The local stellar wind, from the star cluster inside the nebula, shapes the
nebula by blowing away the gas around the star cluster. The stellar wind usually
forms a kind of cavity in the nebulosity. The same stellar wind also initiates the
further collapse of the gas cloud and the birth of the second generation of stars
in the nebula. The collapsing gas can resist the stellar wind and produces pillar like formations which must point to a cluster.

Ionized oxygen (O-III) glows with a bluish light, and since oxygen needs a lot
of energy to ionize it, this can only be achieved relatively close to the star cluster
in the nebula. I use this information to position the O-III area (the bluish glow) at
the correct distance relative to the heart of the nebula.

Many other small indicators can be found by carefully studying the image
itself. For example, if there is a dark nebula in the image, it must be located in
front of the emission nebula, otherwise we can’t see it.

The pillar-like formations in the nebula must point to a source of stellar wind, for the same reason.

How accurate the final model is, depends how much I have known and guessed right. The motivation to make those 3-D-studies is just to show, that objects in the images are not like paintings on the canvas but really three dimensional objects floating in the three dimensional space. This generally adds a new dimension to my hobby as an astronomical imager.

An experimental 3D-study of an emission nebula NGC 1491



This is an experimental test with a 3D-conversion of my astronomical image. Only real elements from the original image are used, there is nothing added but the estimated volumetric information!

NOTE. This is a personal vision about shapes and volumes, based on some scientific data, deduction and an artistic impression.

Info about the technique used

Due to huge distances, real parallax can't be imaged in most of the astronomical objects.
I have developed an experimental technique to convert my astropics to a artificial volumetric models.

My 3-D experiments are a mixture of science and an artistic impression. I collect distance and other information before I do my 3-D conversion. Usually there are known stars, coursing the ionization, so I can place them at right relative distance. If I know a distance to the nebula, I can fine tune distances of the stars so, that right amount of stars are front and behind of the object.

I use a “rule of thumb” method for stars: brighter is closer, but if a real distance is known, I'm using that. Many 3-D shapes can be figured out just by looking carefully the structures in nebula, such as dark nebulae must be at front of the emission nebulae in order to show up etc...

Cone Nebula as an animated zoom in series



I have shot many targets with a several focal lengths and instruments.
Due to that, I'm able to publish some of my photos as an image set, with a different field of view and detail levels. The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.
