Hi all! I didn't get up at 3 am today in vain...
The image is far from spectacular but it nevertheless shows hints of a tail. I observed and I took images from a very humid place next to a small lake in Ostpark, Munich. Results with 10x50 binos were inconclusive, probably due to moisture.
Technical data: Nikon D100, 200/2.8 lens, ISO 3200, composite of 4 unguided images of 2s each about 02:45 UTC. Cropped to FOV = 2.3°.
