In 2021, the proven SBIG 340 allsky camera was replaced by a selfmade camera based on Raspberry Pi using Pi HQ camera model. The resolution is much better and the WiFi connection allowed an optimal place. The only issue during last fall was the fact, that the heaterpower was too week to keep the dome free of dew/frost. This was resolved during service mission in February 2022 by adding a heater in the acrylic dome with adjustable power (PWM).
