Corona virus is spreading all over the world, and so we're all forced to stay home. Here in Poland all shopping centers, schools, kindergarten, playgrounds, etc. are closed. So, together with my wife, we have to find way, to do our regular job, and take care of children. It is time consuming and exhausting. To de-stress I thought, I'll dismount most of my cams and conduct a night time comparison. The weather conditions were encouraging, as there was clear sky and full moon. So here is what came if it. Have a good time and take care, all of you.
