Astro Anarchy gets published
The Cnet published an article about Messier 31, the Great galaxy of Andromeda, photo.
Photo of Messier 31 is produced by collaboration between David Lane and me.
You can read the Cnet article by Michelle Starr from
The Wired noticed us too
Ten must-read articles for 25 September
Our photo is number five on the list

Messier galaxies, M81-M82, with integrated flux nebula
A new collaboration image with David Lane. Beside beeing a deep sky astrophotographer he is also a master of landscape astrophotographing, please, have a look at his homepage: http://www.davelaneastrophotography.com/
Image acquisition is made by David Lane. He sent a massive amount of data to me to process and here is the result, Messier galaxies 81 and 82 with a large amount of dim integrated flux nebula at front of them.
Total exposure time is around 40 hours with the William Optics GT81 telescope and SBIG STL-1100 3 CCD-camera.

Messier 31, M31, the Great Galaxy of Andromeda
Another collaboration image, this time with David Lane. He is also a master of landscape astrophotographing, please, have a look at his homepage: http://www.davelaneastrophotography.com/
Image acquisition is made by David Lane. He sent a massive amount of data to me to process and here is the first result, the Great Galaxy of Andromeda with 37 hours of exposure time.

INFO
The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224, is a spiral galaxy approximately 2.5 million light years from Earth. It is the nearest major galaxy to the Milky Way.
The Milky Way and Andromeda are expected to collide in 3.75 billion years, eventually merging to form a giant elliptical galaxy or perhaps a large disk galaxy.
At 3.4, the apparent magnitude of the Andromeda Galaxy is one of the brightest of any of the Messier objects, making it visible to the naked eye on moonless nights even when viewed from areas with moderate light pollution. It has an apparent diameter of six times as wide as the full Moon
An experimental test
This funny looking image is just stretched vertically to try to show the actual round shape of the galaxy.
It looks like a barred spiral to me.
