Which ISO value did you use?

ISO 1600, which is a good trade-off between Dynamic Range and Dynamic Range Shadow Improvement of the sensor. In one test I tried ISO 800, which provided a little bit less shadow improvement, what is according to the Photon to Photos measurements.But that might depend on exposure time. No further test or experience so far.
For short exposures, e.g. 13sec, to avoid star tracks without tracking I used ISO 3200 - 12800 without seeing differences.
