While I believe the other photos, something about the photo in post#8 strikes me as being 'contrived'. Too much of a black dark difference between the North and the South, that leaves out even any trace of lighting from Pyongyang. Pyongyang's light, as dim as it may be, is certainly just as strong as some of the rural areas I recognize lit in the south, considering the size of the city and eyewitness reports on the ground.
I think when you scroll down you see more accurate photos; one does show a small whitened area for where Pyongyang should be. Just trying to be objective.
