  1. The stars are wonderfully sharp, while the clouds are very blurred, which leads to the question: Was this a relatively short exposure with very fast moving clouds or were you tracking the stars movement during a longer exposure?

    • 6 seconds at f/2.0, which fits within the SSF (otherwise known as the Star Streak Formula) rule of 600/focal length as the longest exposure allowed without having the stars streak.
