The auto-exposure, blending several ones using to reduce the noise and increase sharpness with HDR+ (which is a superresolution kind of algorithm) ends up choosing 1/42s with an ISO equivalent of 573.
For an ISO equivalent of 573, that's quite a bit of noise remaining in the sky, but at least it has a relatively pleasant grain-like texture.
Something that's not good however is that the lens shading compensation is not calibrated correctly , as it's easy to notice a vignetting effect remaining in the sky.
