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.

NGC 5371

NGC 5371 is situated in the constellation of Canes Venatici half way towards Bootes. It is about 110 million lightyears in distance from Earth and its diameter is said to be about 130,000 lightyears. Hence, this face-on barred spiral galaxy is about 1/3 larger in diameter than our Milkyway.


NGC 6207

NGC 6207 (2016)

NGC 6207 is a tiny galaxy next to the famous cluster M13 in the constellation of Hercules. It can be observed in the evening skies during May and June. It is about 46 million lightyears in distance from Earth.


M 104 – Sombrero Galaxy

For its famous shape, this almost edge-on galaxy is well known under the name „Sombrero Galaxy“. The shape is formed by dust lanes projected against the galaxy’s core. This Sa or Sb-type spiral galaxy is located appr. 30 million lightyears from Earth and has a diameter of appr. 50,000 lightyears.


NGC 7814

NGC 7814 is an almost perfect sample of an edge-on spiral galaxy. Watching the galaxy nearly from its equator plane the dust lanes prominently project against the galactic core. This spiral galaxy is situated about 50 million lightyears from Earth and expands about 80,000 lightyears in diameter.


NGC 1579 – Northern Trifid

 NGC 1579 - Northern Triffid

NGC 1579 became famous as the „northern trifid nebula“ for its eye-catching dust lanes apparently dividing the nebula into several parts. A combination of luminescent gas (red) and illuminated interstellar material (blue) add up to the colorful arrangement thrilling the observer to dunk deeply into the scenery.


NGC 2419 – Intergalactic Wanderer

NGC 2419 is often called the „Intergalactic Wanderer“, an appropriate title considering its distance of some 300,000 lightyears from Earth. Compare this to the appr. 160,000 lightyears to the Magellanic Clouds, the Milkyway’s closest satellite galaxies. The Cluster might well be the remains of an ancient galaxy cought by our Milkyway’s force of gravity.


IC 1805 (Melotte 15)

IC 1805 is also know as Melotte 15, which is basically the open star cluster located in the constellation Cassiopeia. Nevertheless, even more stricting than the cluster is the field of H-II nebula surrounding the stars. Our image includes data taken through straight RGB and Ha-narrowband filter to incorporate both the impressive structures and the colorful view.


Abell 78

Located in the constellation Cygnus, this Planetary is a nice target for mid-sized telescopes. The spectrum reveals that while the faint outer halo is made up by usual interstellar matter (mostly Hydrogen), the embedded inner ring consists of pure Helium. This is considered to be a direct evidence of stellar fusion processes.


IC 5146

IC 5146 is also know as the „Cocoon Nebula“. It is located in the constellation of Cygnus in vicinity of the famous North America Nebula. Recent studies consider the nebula about 10 lightyears in diameter and some 3,000 lightyears away from earth. The picture is thus a window back in time to what has been in the year 1,000 B.C.


NGC 772

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.
