Hey guys,
thanks for your friendly welcome!
@astroron: Bielefeld is only 20km away from my place of birth (Versmold - nobody of you will know it

), where I lived the first 22years in my life. Because my parents house already is there I can observe from a dark backyard (fst ~6.0 mag in good nights). If you know Bielefeld you also know the "Teutoburger Wald", a NW-SE striking low mountain chain. There are several dark places where fst reaches >6.5 mag in good nights and my favorite observing site is located there.
I'm only a weekend observer, because I'm now living in Bremen (200km to the north from my hometown), where the night sky is yellowish and DS observing (my fovorite) is disappointing anyway. On most of the weekends I'm back in my hometown to join the dark skies there.
In Germany we say: Sehen wir uns nicht auf dieser Welt dann sehen wir uns in Bielefeld - which means in English something like: If we don't meet on this world we'll meet in Bielefeld (it'm more funny in German if one knows the context

)
Clear skies,
Mathias
