2,6 Meter Classic Dome (Spaltkuppel)

Die Sternwarte wird hauptsächlich für Deep-Sky Fotografie verwendet.
Im letzten Jahr konnte ich eine beachtliche Sammlung an Deep-Sky Aufnahmen unter astrobin.com zeigen:

"Die Stabilität der gesamten Konstruktion ist bemerkenswert. Während der Beobachtung mit einem Baader Microguide-Okular am C11 habe ich die mit Sand gefüllte Säule berührt, an sie geklopft und mich an sie angelehnt. Das Bild im Okular war durch nichts zu erschüttern!"

Mit der Errichtung der Sternwarte ist für mich ein Traum in Erfüllung gegangen. Ich möchte noch einmal einen herzlichen Dank an alle Beteiligten richten.

At the feet of the Aithiopian King Cepheus (Latin Cepheus), one of the well-known constellations of the northern sky, lies - at a distance of 1300 light years - Sh2-129, a faint red hydrogen emission region of type HII. This red nebula holds a mysterious object for us, an elongated blue bubble officially designated Ou4. The blue light from Ou4 took 2300 years to reach Earth and shines through the red hand.

To us, a pandemic-stricken mankind, the heavenly combination of Sh2-129 and Ou4 reminds us of a cosmic hand that offers to all of us a CoVid vaccine vial. One could even identify the thumb-nail and fingers, when concentrating on image detail.

The blue nebula, which glows only in the OIII spectral line It is so very faint that only as recently as 2011 it was discovered by the French amateur astrophotographer Nicolas Outters! Originally, the object was called a bipolar planetary nebula. Recently, however, researchers came to the realization, that Ou4 is a spectacular outflow of material, driven by HR8119, a triple system of hot, massive stars seen near the center of the blue nebula. Incidentally, its extent in the sky is about 2.5 times the diameter of the full moon. This means that this truly gigantic CoVid vial has a diameter of almost 50 light-years!

Astrophotographers will face extreme challenges. Already Sh2-129, the cosmic hand, is one of the faintest objects in the sky. In order to image the blue CoVid vial it is not enough just to increase the exposure time. One needs suitable extreme narrowband filters which block the visible spectrum completely and only show the OIII spectral line in a few nm wide window. But also special techniques of image processing are necessary, to bring out this much detail, otherwise Ou4 would just appear as a faint ghost in this image.
