A small spontaneous weekend experiment shows once again: it is not so easy to photograph a night sky / a starry sky by long time exposure. The longer the exposure time, the more details can be seen – but from about 30 seconds on, the movement of the stars or the rotation of the earth can be seen. With higher ISO I could shorten the exposure time to 2-3-4 seconds, but the digital ‘dirt’ increases.
