Awesome shot Andreas, and yes, there is definitely some 3D going on there.
Paul: For a mint, $1200 is about right. For ones with cosmetic wear but where the glass is in perfect order you can expect to pay about $1,000. The cheapest I've seen have been around $800, but then it was with minor scratches on the glass..
Some assorted shots:
Modern T* coating would definitely do a better job with moon and its reflection:
A bit of cheap 3D..
Some more triangular bokeh: (around f/5.6 I would guess)
