Cygnus zoom in series
Weather, up here 65N, doesn't give any support so I made an other zoom in series.
This time I'm zooming from 23x14 to 0,5x0,7 degrees of sky at the are of NGC 7000 in Cygnus.
Older series can be seen in my portfolio: http://astroanarchy.zenfolio.com/p162076373
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 detail levels.
The fractal nature of our universe stands out nicely by this way and it will make the orientation more easy.
Many times, it's difficult to understand the image scale of astronomical images.
Due that, I will add a Moon circle in some of 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, a study of the apparent scale in the sky.
Note. The apparent size of the full Moon is marked as a gray circle at lover Right corner.
Images are in mapped colors from emission of ionized elements, R=Sulfur, G=Hydrogen & B=Oxygen.

Cygnus collection as a poster
Treasures of Cygnus
I made a collection out of my images from the Cygnus constellation.
At center lays a giant 18-panels mosaic of Cygnus nebulae as a natural color composition. Surrounding closeup images, seen in large central mosaic, are in HST-palette. All images are shot with the Baader narrow band filter set, H-alpha, S-II & O-III.
Original, full resolution, poster has a massive size, ~21.000 x 16.000 pixels!
All images used in this presentation, with technical details and labels, can be found from my portfolio at:
Ps.
This mid winter has been worst I can remember up here 65N... Over two Months 100% cloud cover and it doesn't look any better in near future either. Very frustrating.

Last day of 2011, a collection of images.
Happy New Year 2012
Since this is a last day of year 2011, I have made a collection of images from the Autumn season 2011. As usually at this time of year, the weather has been very cloudy, up here 65N. Last couple of months has been blocked 100% by clouds. I managed to use every clear moment, so there are quite a few images from this Autumn, including my main work, a giant 18-panel mosaic from the Cygnus constellation.
