It looks like.... a collection of my photos as I see them
We have had a solid cloud cover, up here 65N, over two months now. My new imaging system stands useless at the rooftop, very frustrating.
We are easily seeing quasi logical forms in random shapes since we have a most powerful shape recognition machine in our brains. Based on previous phenomena, I made a funny collection out of my photos. There is an original version of my photo and same photo as I see it in my head. Part of the images are named after my own observations and some are commonly known nicknames. NOTE. All of the astronomical photos in this blog post are originally taken by me.
It looks like...

Astro anarchy gets published, an art gallery just opened!
For this holiday season I got invited to participate to a temporary art exhibition "Joulun Tähdet" (Stars of Christmas" in my home town Oulu.
We now have a small gallery opened at the very center of the city for about one month.
Beside my astrophotos, there are oil paintings from Matti mikkola and some older nineteenth huderts century paintings from the collections of Kuru Koru. There are also some special collectables and antique for sale from kuru Koru's collections too.
Our address in Oulu, Pakkahuoneenkatu 10, "Vanhan Apteekin talo", at street level.
We are open daily from 12.00 to 18.00 until christmas.
You Are very welcome!
Some pictures from the gallery

Sharpless 132, Sh2-132, in visual spectrum
I published the original photo of Sharpless 132 at November 11 but only in mapped colors. In this version, the narrowband channels are combined so, that the resulting image is as close as possible to a visual spectrum of human eye. Red is the dominating color since the ionized hydrogen, H-alpha, is the strongest emission line and it's emitting deep red light. Blue hues are coming from the emission of an ionized oxygen, O-III.

Sharpless 132 (Sh2-132) in Cepheus
Image is in visual colors, if human eye could be able to see colors in extremely low light, most emission nebulae appears in deep red color due to dominance of an ionized hydrogen, H-alpha. Blue color is coming from the emission of an ionized oxygen, O-III.
An experimental starless version
A closeup composition
INFO
Sharpless 132 is a very faint emission nebula, it locates at the border of Cepheus and Lacerta. Distance is about 10.000 lightyears. My photo covers about one square degree of the sky (63x63"). The blue color in the image is from the emission of an ionized Oxygen (O-III). "The divine blue light" at horses face seems to be an Oxygen jet of some kind, or it's just a tens of light years long oddly shaped area of glowing gas. The shape can be seen in H-alpha channel too.

Soul Nebula, IC 1848, as a two frame mosaic
This image is originally shot this Autumn between 27 and 29.10. I haven't publish it before, since I have had so much material to share. The new imaging system gives me a nice field of view, with a high resolution.
63x63 arc minutes at a scale of 0,95 arc seconds/pixel. That's over a square degree of sky.

Mapped colors from an emission of the ionized elements, Red=Sulfur, Green=Hydrogen and the Blue =Oxygen. The photo is stitched together from two separate shots.
An experimental starless view
Details of the actual nebula stands out better in this starless view.
Info
Soul Nebula, (Sh2-199, LBN 667) is an emission nebula in constellation Cassiopeia. IC 1848 is a cluster inside Soul Nebula. Distance is about 7.500 light years. This complex is a Eastern neighbor of IC 1805, the "Heart Nebula" and they are often mentioned together as Heart and Soul.
A wider field photo
In this wide field image of mine, the Soul Nebula is shown with its neighbor, the Heart nebula. Image is shot with the Canon EF 200mm f1.8 lens, Baader narrowband filters and the QHY9 cooled astronomical camera. My older photos of the Soul nebula can be seen HERE

DWB-111, the Propeller nebula
The data for this object is shot at 31.10 last month but I got it processed just now.
The data for the emission of ionized Oxygen and Sulfur (O-III and S-II) is borrowed from my wide field shot of the area back from the first light image of Autumn 2011.

Info
Propeller Nebula (DWB 111, MRSL 497). This S-like formation is part of the much large area of emission nebula in constellation Cygnus. There are very little information about the origin and distance of this structure is unknown.

A furious cosmic horse gets blinded by a divine blue light
My latest photo, Sh2-132. I rarely give a name to my photos, other than the official catalog number or well known nickname, this time I couldn't resist to give a name of my own.

Why a furious horse?
A marble horse sculpture from Piazza Navona, Rome Italy, it's placed in the image to show the horse figure.
INFO
Sharpless 132 is a very faint emission nebula, it locates at the border of Cepheus and Lacerta. Distance is about 10.000 lightyears. My photo covers about one square degree of the sky (63x63"). The blue color in the image is from the emission of an ionized Oxygen (O-III).

(Ionized Hydrogen)
The actual nebula is much large, as can be seen in my older wide field photo of the area.
Area of interest is marked at my older wide field image of the Sh2-132. The original image from the Winter 2011, with technical details, can be found from HERE

Astro Anarchy gets published
I shot my astronomical photos about five years from the rooftop of the Swedish Private School here in Oulu, Finland. Last year I had to find another location since they started to build an expansion for the school at the rooftop. I was so glad, when Anders Wentin from the school contacted me and ask, if I'm able to deliver an artwork from some of my photos to the School. Yesterday, at 6. 11. 2014, the artwork was revealed.
The photo is printed on dibond aluminium sheets and covered with a hard and glossy laminate. The size is 3600 x 1600mm (142 x 63 inch). There are three panels used for the final artwork. Seams are so thin, that's not possible to see them easily.

My previous large print
Artwork above is not a largest print made from my photos. Much larger one was published at spring 2014. More ifo about this gigantic, over 10 x 3 m, print can be seen in this blog post: http://astroanarchy.blogspot.fi/2014/04/astro-anarchy-get-published.html
The Cirrus of Cygnus
A very large photographic print on aluminium, 3x10m
Even in that size, the image is very sharp, since the original image is in very high resolution due to mosaic technique used. An info board for the artwork can be seen next to the door at middle right.
This photo is actually a upper part from the very large cygnus mosaic. The new print is the lower part of the mosaic. Here is the original photo of the whole area.
