Astro Anarchy get published


Yesterday was an opening ceremony for the new facilities of The "Oulu Region Joint Authority for Education" in Haukipudas. One of my images was selected there as a public artwork in a main lobby.

The Cirrus of Cygnus
A very large photographic print on aluminium, 3x10m

The photo is printed on aluminium and it has a glossy finishing. This is one of the largest art prints I have ever seen. The size of the photographic prin is over 3 x 10 meters (= 10 x 33 feet) 
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.

About the photo
Click for a very large image, 3000 pixels wide and 4,5MB

A mapped color image from the emission of ionized elements,
R=Sulfur, G=Hydrogen and B=Oxygen.

The image above spans about 15 degrees of sky horizontally, that's 30 fool Moons side by side in a sky!
There are nine panels seamlessly stitched together. Each panel has been shot three times for a color image by using emission line filters for Hydrogen, Oxygen and Sulfur. A camera lens, Canon EF 200mm f1.8, was used with a cooled astronomical camera, QHY9. Original image is about 20000 pixels wide . Total exposure time is around 90h.

The "Cirrus of Cygnus" is a part of a much large image of this area. 
Note! a very large image, 2300 pixels wide and 4,7MB
The Cirrus formation can be seen at upper part of the image above.

It does look like a Cirrus cloud

Two collections of planetary nebulae in scale


Since I don't have any equipment to continue my imaging work, I have organized my image archives. This time I made an image collection out of the planetary nebulae imaged by me. I'm trying to show here, how large they appear to be in the sky. There is an image of the Moon as a scale in the posters. The Moon has an angular diameter of about 30 arc minutes, that's equal to 0,5 degrees. I have made a similar poster out of the supernova remnants, it can be seen HERE.

NOTE!

A friend of mine, Sakib Rasool, contacted me for this posters. There is an error in second one.
Sh2-223 is actually an emission nebula. You can read a paper about it here: http://www.aanda.org/articles/aa/abs/2006/29/aa4881-06/aa4881-06.html

Best amateur astronomy photos of the past four years, by the Telegraph




My photo of the constellation Cygnus was selected as one of the best amateur astronomy photographs of the past four years by the Telegraph. The collection of images can be seen HERE, my image is a number 09.

A mosaic image of constellation Cygnus 
Reprocessed, NOTE. a large image 2300 pixels wide and 4.3MB

Image is in mapped colors from the emission of ionized elements, R=Sulfur, G=Hydrogen and B=Oxygen. Native size of  this image is over 15.000 x 10.000 pixels.
