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.

APOD, Astro Anarchy gets published

Astronomy Picture of the Day

My Image of the "Crescent Nebula", NGC 6888, was selected as an "Astronomy Picture of the Day" by the NASA.
You can see the NASA page here: http://apod.nasa.gov/apod/ap120816.html

This was my Fifth APOD, previous ones can be seen here:

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.

Note. The apparent size of the full Moon is marked as a gray circle at upper Right corner.

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
