As the Sun rises over the mountain, wind turbines are a problem that we have to wait until the Sun rises above them:

A Seestar S50 was used to capture a 3 minute RAW AVI Through a Baader OD 5.0 solar filter and a Baader Ca K-line filter, controlling the brightness,exposure and gain so that the blue channel was not overexposed. The best 60% of the frames were debayered and stacked in Autostakkert!4. The blue channel and the RGB image were wavelet processed in waveSharp, post processed and combined in the Gimp 2.10.
