        Most phone cameras give up when the sun goes down. Nocturne was built for exactly that
        moment: it holds the shutter open for up to thirty seconds, steadies every frame against
        your hands, and stacks them into one clean exposure.

      </h4>
      <p className="mt-3">
        Point it at the sky and Nocturne quietly takes a few hundred short frames. It lines them
        up on the stars rather than the horizon, so the Milky Way comes out sharp even as the
        ground drifts. It all happens on the phone, in about the time it takes to lower your arms.
