2010, my second image of the Month award





An award certificate



 An image of the "Lagoon Nebula", M8, was selected as a image of the month in Northern Galactic international astronomical imaging group.

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!

NGC 6357, Sharpless 11





HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen


Natural color composition from the emission of ionized elements, R=80%Hydrogen+20%Sulfur, G=100%Oxygen and B=85%Oxygen+15%Hydrogen to compensate otherwise missing H-beta emission.
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!

The telescope and technical information:

16" RCOS ja Apogee U9000 camera. 
LRGB combo.
H-alpha 4x1200s, Dark and artificial Flat calibrated.
1xO-III 1200s, Dark and artificial Flat calibrated.

Raw data is shared with "Team Finland"

Processing workflow:
Image acquisition, MaxiDL v4.xxx
Stacked and calibrated in CCDStack.
Deconvolution with a CCDSharp, 30 iterations
Levels, curves and color combine in PS CS3.

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.
The image is in HST-palette from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen

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. 

The telescope and technical information:

16" RCOS ja Apogee U9000 camera. 
LRGB combo.
Luminance 9x600s., Dark and Flat calibrated.

Viewing 3D





Finnish-Suomeksi
Nähdäksesi anaglyph 3D-kuviani tarvitset Puna-Sinilasit!
Ne ovat yleensä erittäin edullisia, 1-2€,  ja helposti ostettavissa onlinemyymälöistä.
Suomessa laseja voi ostaa ainakin täältä:
http://www.dealextreme.com/search.dx/search.3d%20glasses 
HUOM! 
Lasien linssien täytyy olla PUNAINEN ja SINININEN, jotta kuvat näkyisivät oikein.

-
English
To see my anaglyph Red/Cyan 3D-images, you'll need a right kind of 3D-eyeglasses!
They are usually very inexpensive and can be bought online easily.

Here are few links:
USAhttp://www.berezin.com/3D/3dglasses.htm

There is many online sellers for 3D-glasses, google them down to find a suitable seller in you area.



EDIT. Finnish only, sorry!

Huomasin juuri, että samassa Suomalaisessa verkkokaupassa, jossa myydään 3D-laseja, on myynnissä 9€ hintainen stereokuvien katselulaite:
http://www.elektroni.fi/?product=5452

Ko. laitteella voi katsella stereopari-paerikuvia 3D-muodossa!


Täältä voi tilata stereoparikuviani valokuvinahttp://astroanarchy.zenfolio.com/p272573124
Hinta 1,95€ kappale, vähän isompi koko, joka vielä toimii, 3,95
Katselulaitteen kanssa siis toimivat vain "parallel vision" tekniikalla katseltavat kuvat.

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.
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)
