3/ The reason the right-most bands look brighter is that the Sun passed over that region twice, as my exposure was 8 months long (more than half a year).
That tower in the foreground is the seeing monitor, which we use to measure the blur/twinkling of the stars due to the atmospheric turbulence.
In the background you find the cylindrical domes of our four 8-m telescopes.
