Thank you very much, Makis.

Cheers, Michael.
I was over the Moon with this shot :)

The horizontal field of view is 9.1º and the moving object is at 2000 m. Simple trigonometry allows me to calculate that the whole frame span is 320 m. The most upper streak measures 815 pixels vs 5593 pixels for the whole frame. That means that the object moved 46.6 m in 8 s = 21 km/h = 11,3 knots
QED :)

Exactly! That's also the role of ephemeral art.

The drawback of this technique is that a tripod is recommendable for more than 5 frames...

That's one of the ways to put it :D
