All­sky Dewheater

Mar. 2022 | Blog, France, Infrastructure

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).

About Me

Hello, my name is Martin Rusterholz. I’m a Swiss amateur astrophotographer living near Zurich, the biggest town in Switzerland. My interest in astronomy started when I was 16. At that time, I built my first Newtonian telescope and mount. I studied physics at the Swiss Federal Institute of Technology (ETH) which was the only study including at least some aspects of astronomy and astrophysics. “Looking at the nights sky is an experience touching everybody deeply inside, something common to all human beings independent to the language spoken by the individuals”. Deep-sky astrophotography is my passion.
