Thought I'd try submitting this shot even though the stars are blurry, because the mountains in the foreground are sharp. It was rejected for being out of focus.
Camera settings: f2.8, 800ISO, 30 seconds, focus set to infinity
Even when I bump up the ISO and decrease the exposure time, the stars are always out of focus.
I'm wondering if this image should be acceptable with blurry stars, or if there's something I'm missing about how to shoot the Milky Way.
