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!

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.

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.

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. (Ionized Hydrogen)
