Who expected that normal daylight is sufficient to let the stars shine at bedtime will be disappointed. My bedroom has a double window on the north side. In normal daylight, the stars shine only very weak, and not too long. At bedtime in winter they have long been extinguished. Presumably it would work better if the window would show the South side, but I can not judge. In fact I have now if I want to enjoy a starry sky, the stars illuminate the ceiling lights an hour before directly. Would I so probably not order again.
