Welcome to the Astro-Kooperation!
The “Astro-Kooperation” was formed back in 2003 by Stefan Heutz and Wolfgang Ries as collaboration in our common interest astrophotography. Michael Breite later joined in and today we form an alliance of three amateur astrophotographers sharing the fascination for the wonders of the universe.
On this website we are pleased to present some of our images of the most beautiful objects in the heavens.
Scroll down for our recent images!
NGC 772 (no. 72 in Arp’s catalogue of peculiar galaxies) is a spiral galaxy (Type Sb) located in the constellation Aries. At a distance of some 130 million lightyears from earth it has an actual diameter of about 100,000 lightyears and is thus about as large as our milky way. The remarkable disturbed shape is caused by its interaction with its neighbor NGC 770.
NGC 6842 is a nice Planetary with a visual diameter of less than 1 arcminute. It has a distance of approximately 4,500 lightyears from earth.
NGC 6802 is a remarkable open cluster with an unusual almost rectangular shape. It is located in vicinity of the well known “coat hanger”, a bunch of stars in the characteristic arrangement.
NGC 6426 is a tiny globular cluster (class IX) in the constellation Ophiuchus. It is located at a distance of some 67,000 lightyears from Earth. Its spectrum reveals it to be metal-poor. It is believed to be about the same age as the popular M 92 in the constellation Hercules.
M 15 is the highlight in globular clusters in the autumn skies. Its age is believed to be about 13 billion years, hence its stars being almost as old as the universe itself! Located to the west of Pegasus it can easily be seen in the smallest telescopes. However, it requires large optics to resolve the core of this magnificent cluster.
In very steady skies, M 15 reveals a curiosity: The tiny Planetary Pease 1 located right within the cluster. Its visual size is only 3 arcsecs, therefore it must be about 0,98 lightyears in diameter.
