Nice image.

In the astro forum most purist actually seem to favour a Daylight WB setting to avoid the blueness. It is a personal taste thing though.

I am quite surprised by the roundness of most stars. I was expecting to see more elongation at 15 seconds on a 32mm lens on APS-C. In FF equivalent terms this would be Rule of (32 x 1.6 x 15) = 768. Most modern sensors tend to start generating star elongation (trailing) around 200-300. The old Rule of 500 is usually successful only on old film cameras or old low-res digital. I know that I start seeing it at anything over 20 seconds (and even at 20 seconds in places) on my 6D ii + 14mm f2.4, which is 280, so a long way from 768.
