This is a crop of the previous picture focusing on the airplane. While a little blurry (I obviously had focused on the moon) there is still considerable detail. The plane must have taken off at Düsseldorf or Cologne airports just shortly before I took the picture. Judging from the four engines, they would be in the air for quite a while ...
Picture details: Exposure 1/250s (manual), aperture 8.0 (fixed), focal length 500mm, ISO 200, no flash, tripod.
