It isn't centered, indeed. I tried to show the contrails, taken at 1/30sec.
The shot was even more amazing for me, because I only tried a picture, just to see, how light conditions were. As always, when I start taking pictures, I make 2 or 3 shots to check settings and so on. That was one of those shots of the first aircraft, which arrived that day.
I even remember, that three well known A.net photographers came a bit too late and missed this one
