This is my first star trail photograph stacked with StarStaX and can't seem to find out why they are so blurry.
I have a sturdy metal tripod with a cable release and shined a light to focus on the foreground beforehand. The image is at f/4 aperture, 30 second shutter speed, ISO 250, with a 24 mm focal length and manual focus on. Any advice would be helpful and don't be afraid to ask for any other pictures to help me figure this out.
