This is so cool. Nice creativity.
You also caught a satellite tracking across the sky.
Neat photo, thanks!
Actually, I believe it's an airplane. Notice the intermittent bright blips, corresponding to flashing wingtip lights.
Here is an example I did in 1993 of the Watzmann in Bavaria.
Great shot, in any event.
Great photo. I saw another one of similar type (longer exposure time) here:
It also shows lights on the wall but due to longer exposure time - I guess?? - you can track the climbers' movements on the wall.
very nice exposure. I don't think it is 20 minutes though the star trails don't look long enough.
