Originally posted by awscreo Im not sure, but I think he tried to show that due to noise suppression star trails are thick and less defined with K-1 II.
Could be, but absent a comparison from a K-1 Mark 1, or another similar high-end DSLR using the same exposure settings, it's hard to tell if what is shown is good or bad. And star trail photography is an even smaller niche than regular astro or Milky Way photography, so I'm not sure that Pentax would care one way or another about poor performance there, if it's better in general low-light photography.
And don't get me wrong, some of the night photos MJKoski has posted are great, and I get his general question...I'm just not sure that post added much.
