Planetary experimentation

I've wanted to do this for quite some time now. It's officially called a polar panorama but also named spherical or planet panorama. It's a 360° panorama of the Platz der Republik in Berlin. On top, you'll recognize the Reichstag and on the left is the Bundeskanzlerei or the washing machine as it's popularly known.
In total 42 shots went into it and after about 8 hours of crunching, this is what I ended up with.
