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.

M 15 and Pease 1

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.

NGC 6888

NGC 6888 is known as the Crescent Nebula located right in the heart of Cygnus. The nebula is a so called Wolf-Rayet nebula. WR stars are very hot and massive stars blowing off their outer shells. NGC 6888 is energized by WR 136, the bright star in the center of the nebula.

Make sure you also have a look at the straight H-alpha image.

NGC 6229

NGC 6229 is the third globular in the constellation Hercules. Despite the nice contrast to two bright foreground stars, it is rarely images, most probably because of its vicinity to M92 and M13. The image also reveals numerous background galaxies < 17 mag.

NGC 4565

NGC 4565 is seen nearly edge-on. Hence, the dust in the main disk is projected onto the central bulge. We can see it as a subtle dust lane crossing almost the entire galaxy. Our image is not as deep as expected because it was taken in severely hazy nights.

NGC 6946

NGC 6946 is an almost perfect face-on spiral galaxy located in the constellation Cepheus. A large telescope reveals manifold detail. While the center and the inner arms are traversed by remarkable dust lanes, the star forming regions in the outer rims of the spiral arms stand out in prominent deep red.

Make sure to also look at our deep image which highlights the dim tails of the spiral arms.

NGC 6939

NGC 6939 is an open cluster in the constellation Cepheus. Despite its large dimensions (appr. 10×10 arcmin.) it is often overseen due to its close vicinity to the famous spiral galaxy NGC 6946.

SN 2013ej in M 74

On July 25, 2013 a Supernova (SN2013ej) was discovered by Lick Observatory Supernova Search Program at a magnitude 13.5 mag. Within only 2 days, brightness rose to 12.6 mag. and reached its peak on August 4 (10 days after its discovery) at 12.4 mag. SN2013ej is Type II-P. Type II-Supernovae are final bursts of heavy stars with appr. 10 – 30 solar masses. Following the link to the left, you can as well find an animation with an image of M74 as of 2011.

M 56

M 56 is a Globular Cluster in the constellation Lyra, visible in the summer skies. Despite its total magnitude of appr. 9 mag and a diameter of appr. 9 arcmin, it is sometimes missed because of its relative vicinity to the famous Ring Nebula M 57.
