Description

Einer meiner Nebelfavoriten, Das Auge Gottes. Mit nur maximal 20° Horizonthöhe,
ein schwieriges Objekt in Mitteleuropa.
Nur zwei Nächte Anfang September mit guter Horizont Sicht hatte ich zur Verfügung.
Da konnte ich zumindest Ha und OIII machen. Ich wollte eigentlich noch LRGB nachlegen, aber die Bedingungen waren einfach zu schlecht am Horizont.
Da jetzt ja die Saure Gurken Zeit für Astrofotografie in Deutschland wieder begonnen hat, verschieben wir es auf nächstes Jahr.

One of my nebulous favorites, The Eye of God. With a maximum of 20 ° horizontal height, a difficult object in Central Europe.
Only two nights in early September with good horizon view I had available.
At least I could do Ha and OIII. I actually wanted to add LRGB,
but the conditions were just too bad on the horizon.
Since now the sour cucumbers time for astrophotography in Germany has started again,let's move it to next year.
