Not bad, but it definitely doesn't look like 27 hours of integration, especially at f/5. It seems more like the total integration is around 3 hours.

They built a sports field near my yard and plastered it with a ton of lights. It’s really disruptive. This year, clear skies have been extremely rare—either cloudy or dust storms. So I’ve been collecting only 20–30 frames per session since September. That covers the objective factors. As for subjective ones… well, clumsy hands are still a thing. I’m trying to improve as much as I can. But for now, this is what I’ve got.
