how do you stack shots? this is exciting to me because most of the pictures like this have like 30 minute exposures while most of the cameras I'm looking at only have like 30 or 60 second max exposures but apparently that can still be used to do stuff like this.
It's rare to see the increasing radius to the point where the paths borderline on straight. That makes it unique and interesting. I wish the sky were darker though, so that the individual star trails would be more prominent. Some of the more minor ones seem to be getting washed out. The inclusion of trees was a good thought to add some grounding.
