Pelican nebula as a zoom in series




I have shot many targets with several focal lengths.
Due to that I will publish some of my material as image sets, with different field of view and level of details.
The fractal nature of our universe stands out nicely in this way and it will make the orientation easier.

Many times it's difficult to understand the image scale of astronomical images.
Due to that I have added a "Moon circle" in the images to show the angular scale in a sky.
The full Moon has an angular size of ~30 arc minutes, that's equal to ~0,5 degrees.

Cygnus zoom in series, the "Crescent Nebula, NGC 6888



Due the high latitude, 65N, deep sky astronomical imaging can't be done up here yet.
Instead I made an other  zoom in series from my older material to show the apparent scale in the sky.

This time I'm zooming from 23 to 0,3 degrees of sky at the direction of NGC 6888 in Cygnus.

I have shot many targets with several focal lengths. 
Due that, I will publish some of my material as an image sets, with different field of view and level of details.
The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.

An exhibition, Astro Anarchy get published



An photographic exhibition, 28.05 - 31.08. in Oulu, Finland
Every day between 9.00 - 18.00 in Terveystalo, ODL, Albertinkatu 16

This is a joint exhibition with my friend Esa Jormakka, an orthopedic doctor and nature photographer.


A panoramic view


Opening day was at 28.05. 2012 in my home town Oulu. A private hospital, Terveystalo, offered the bottom floor for exhibition area. It's a great place, with lots of natural light, at very center of city. If you'll like to take a visit, the address is Albertinkatu 16. The exhibition will be open whole Summer up to 31.08.2012, every day between 9.00-18.00

Random images from the exhibition

The artwork at center is about 1,8 meters high and 1,1 wide ( 6 x 3,7 feet)




High wall of main lobby, with panoramic images, the top most artwork is Four meters long. (13,3 feet)


The Moon, center image is 2,5 meters long. (8,3 feet)





Both images are 1,5 meters long ( 5 feet)


Yours truly at Right...
