Wanted to see whether I could catch Comet Swan with tracker+camera+lens from this latitude. Since the comet is not all that high in the sky, there is a rather a lot of air pollution which, even with a filter, makes it hard to use exposures over 30-40 seconds. The Ketelmeer is at approx latitude 52.3 degrees North.
