An anaglyph Red/Cyan 3D-slideshow of my photos
You'll need Red/Cyan Glasses 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.
NOTE
All the original 2D-images are imaged by me.
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)

It's over... no more astroimaging for me... sigh
The Winter season 2012-2013 starts to be over up here 65N. We'll loose dark nights for about six months, due to high latitude. Past Winter was kind of cloudy but since my observatory locates next to my home, I was able to use nearly every clear moment during the Winter.
Image count is relatively high since many of the images are just finalized in this season and there have been material from past years to continue to work with. I have published 24 new images ( Plus color and other versions of them.)
Beside traditional astronomical images, I have done some experimental work by adding a volumetric information to my images. My 3D-work gets widely published by several medias, like Wired magazine, Smithsonian Institute magazine, PetaPixel and many many others.

At end of the year 2012, one of my experimental 3D-images was selected as one of The Best Astronomical Images of 2012 by the astronomer Phil Plait.

Last day of 2011, a collection of images.
Happy New Year 2012
Since this is a last day of year 2011, I have made a collection of images from the Autumn season 2011. As usually at this time of year, the weather has been very cloudy, up here 65N. Last couple of months has been blocked 100% by clouds. I managed to use every clear moment, so there are quite a few images from this Autumn, including my main work, a giant 18-panel mosaic from the Cygnus constellation.

It's over...
Many thanks to all followers and readers
Tomorrow, at 08.04., we'll be out of astronomical darkness.
Due a very northern location, 65N, we have a mandatory pause in astronomical imaging up here.
Next time we'll have real astronomical darkness, about an hour, at 06.09.
As always, I feel kind of sad, since I'm forced to give up my beloved hobby (read addiction)...
Even though I can't do any astronomical imaging up here, I'll keep publishing my experiments here in my blog!
The mandatory Summer brake gives me an opportunity to further develop my methods and fine tune my imaging hardware for the next season.
This imaging season, 2010/2011, I managed to use every single clear night,
the total number of images is not very high though, due the cloudy Winter season.
There are 19 individual images imaged from Oulu, Finland and 18 images imaged with an Australian remote telescope (Northern Galactic Group). Remote images are imaged mainly during Summer and Spring 2010.
I hope, that I will have a possibility to use some remote instrument at this Summer season too, nothing is sure yet though.
Here is a slideshow from a collection of all my astronomical images from the season Autumn 2010/Spring 2011.
As usually, there are two versions of narrowband images, one in HST-palette and an other in "natural colors"
Direct link to the images above, with technical details: http://astroanarchy.zenfolio.com/p198557669
Generally I'm happy with results from this season. I managed to get some very rare objects imaged, like some extremely dim Planetary Nebulae and Sharpless catalog objects. Beside that, I have further developed my processing techniques. (A new version of "Tone mapping", TM v2.0, will be soon ready to publish.)
One APOD from this season too!

All my images from the Autumn/Summer season 2010
The year 2010 is about to end.
Here is a collection from all of my astronomical images from Summer/Autumn season 2010.
I can't do any imaging from my observatory during Summer months, due the high latitude, 65N.
I was lucky enough to have an access to a Northern Galactic groups Australian remote telescope for few months this year.
Happy new year to all readers and followers!
The whole collection can be seen in my portfolio, with the technical details:

The end, it's officially over today!
All my season 2009-2010 images as a slide show.
THE END
Up here, 65N, astronomical darkness is not happening after today, 08.04.2010, until late September, 05.09.2010.
Here is a collection from all of my astro images from this winter season.
Images are in chronological order, latest at last.
The season 2009 -2010 was no good for imaging. Due the bad weather, I was able to capture only 16 separate images in a whole season, even though I used every possible opportunity to image.
I feel kind of sad, as I'm forced to wait until late September to be able to do any night sky imaging again.
I'll post regularly news about my latest development work though, so stay tuned.
