Last weekes more and more dust particles are gathering on the CCD sensor of the Artemis. I cannot calibrate them out using flat-fields, so it is time for a cleaning action.
First I have to figure out how to take the Artemis apart. After 1 hour of careful work I am looking freely at the sensor. This picture shows the backside.
After cleaning the sensor with swabs and alcohol I built the camera together. Here I am shooting flat-fiels on my EL panel to verify if the action was helpful....
It was, here is the new one, most dust particles are gone now.
