This is not a true night image. The sun is still at 30 degrees (since at the moment low sun altitudes result in exploding computing time, more than a factor 10.000 slower than daytime simulations), but the overall exposure time has been set very low to create a dark image, whereas the stars have been added here with an appropiate brightness. Surely this is not the last stage in nightsky simulation, but one step in this direction. At least it might be considered a moonlit scenerey. But let's have a look back to the daytime, but now with a higher observer position.
