Sh2-221, a supernova remnant in Auriga
I think, this is the first three band color image, showing the whole Sh2-221, in the World.
This was one of the most difficult targets I have done so far. Supernova remnant Sh2-221, SNR G160.4+02.8, HB9, locates in constellation Auriga and has an angular dimensions about 2.5 x over 3 degrees. I never seen or red about the extended ionized Oxygen area, visible in my image as blue.
About 33h of exposures with extremely fast camera optics, Canon EF 200mm f1.8 @f1.8, was needed for this image. Total exposure time for the mosaic image, with a Planetary Nebula Sh2-216, is about 58h.
This could be the very first narrow band color image in the world out of this target. Generally, there are very few images of it. I couldn't find an other image showing the whole remnant nor other channels, than H-a.
I have shot this area before but at the time part of the Sh2-221 was missing. This new image of mine is much more accurate and deep.

The Supernova remnant Sh2-221 (SNR G160.4+02.8, HB9) locates in constellation Auriga, about one degree West from Capella. (Doesn't show in my image) The distance from the Earth, 2600 light years, is determined recently at 2007. This object was recognized as a supernova remnant back at seventies.
A two panel mosaic image of Sh-221 and Sh2-216
Two ways to end a life of the star in a same seven degrees field of view!
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. )

Astro Anarchy gets published
My works are selected as a public content for a pedestrian zone in my home town Oulu, Finland.
There is a very large display unit at the end of the zone, 5.12 x 3.2 meters (over 16 x 10 feet). Four different sets of my astronomical photographs and animations are running there as a slide show, January 2014.
I have had my images in the same public screen before, January at last year. This time there is not only normal images but also my experimental 3D-work. The show will run at every 15-25 minutes or so and last about three minutes at the time.

If there are no viewers, I'll stop posting my 3D-experiments, since they can be kind of confusing.

All of my images from the year 2013
This is a poster format presentation out of my images from the year 2013. There are couple of my favorites, like a two panel mosaic of Melotte 15 area in IC 1805, the Heart Nebula, at bottom middle. An other favorite of mine is a rarely imaged supernova remnant in constellation Cygnus, the G65.3+5.7SNR at bottom right.
Two optical configurations was used, Meade LX200 12" and a Canon EF 200mm f1.8 camera lens.

All of my images from the Autumn season 2013
This season was kind of unlucky to me. I planned to shoot longer focal length images at this Autumn with my 12" Meade. Unfortunately there was serious technical problems with my gears and I was forced to move to a wide field instrumentation. All this took lots of time and top of that, the weather up here, 65N, wasn't very supportive. My main work for the autumn season 2013was a rarely imaged supernova remnant in Cygnus known as G65.3+5.7SNR
A collection of my images from the Autumn season 2013 as a poster.

Some new experimental work
I made a series of artworks out of my astronomical images by flipping and rotating the image. Every picture is made out of the single astronomical image of mine. The result shows the Nebula at many different orientation simultaneously. All my experiments can be found from my PORTFOLIO Do you recognized what has been the original astronomical object?
Vision XII, from the series Visions of Space
This is one of my artworks based on an original astronomical photograph shot by me.
Image belongs to a large series of images called Visions of Space.
Note. Image is manipulated but all the elements in it are from a real astronomical object.
Some publications
I got my sixth NASA APOD (Astronomy Picture of the Day)
I have made several 3D-studies out of my astronomical images. Couple of my animations gets widely published, here are few samples:

3D-studies of the Veil Nebula supernova remnant
The weather doesn't support the imaging of the new material, so I made a collection of an experimental 3D-studies out of the Veil nebula SNR. Some of the images are new but couple of them are published earlier.
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.

A start of the new project, Cepheus mosaic part1
I'm about to make a similar mosaic out of constellation Cepheus, than I made out of constellation Cygnus.
The first part is ready now. It's a four panel mosaic showing two main objects, IC 1396 and the Sharpless 129 (Sh2-129). I managed to get visible an extremely dim planetary nebula candidate, OU4, inside the Sharpless 129.

At this first part of the Cepheus mosaic, there are four individual panels stitched together. At lower right corner, there is the Sharpless object 129 (Sh2-129). The blueish area, inside Sh2-129, is a recently found plaentary nebula candidate, OU4. The famous astrophotographer, Nicolas Outters, has made this discovery, HERE is a paper about it. OU4 is an extremely dim formation. 11h of O-III light with very fast Canon 200mm EF f1.8 camera lens, was needed to have some hint about it.
I will continue this project, as soon as weather allows. The final mosaic will be 10-14 panels larg
