Horrifying, and already partially true. Here in Stockholm area, I
cannot make clean long exposures due to constant traffic overhead.
This comes in the form of not only aircraft, but a fantastic
amount of space debris, satellites, and most problematic, iridium
flares. I used to be concerned about fireballs or the aurora. I
regard myself as lucky to make a clean 30 second exposure on a
field larger than 1.5 degrees of sky.
