Smog

Old Konrad lives in his house on the slope of an imposing mountain cliff. He loves to observe the stars from his balcony with his self-built telescope. But in the huge city that stretches under his mountain, industrialisation has begun and large smoking factory chimneys cloud the sky with black smoke. Konrad can no longer see the spectacular sky events. But he finds a solution through his tinkering abilities to be closer to the beloved stars than ever before.
