Tonight the sky stability is fairly good. After struggling for two nights with the ZWO ISA120MC I finally gave up. I switched back to the DBK21MC618 camera.

The DBK camera is more easy to handle with and gives a higher contrast, lesser noise. The ZWO camera needs experts to handle with. I am far from expert.
