Me wonders how they constructed this composite image with no star trails but so many meteors. Nevertheless, I remember the many nights me and my brother camped in the backyard on August 12/13, just looking up and seeing maybe one meteor every couple minutes or so.
A telescope with a clock drive aligned properly will keep the starfield steady. It compensates for the Earth’s rotation.
The camp where we slept for a couple weeks -- at the foot of Mauna Kea mountain -- has a remarkably clear atmosphere -- and just like you said -- meteor after meteor could be seen, maybe a hundred per hour under the pitch black sky.
But like every beautiful site on this Earth: after you've seen it for a while, it gets boring and no longer holds the charm it once did. Would love to see it again however.
At the top of the Mauna Kea mountain lies a few national observatories and international observatories — and it's the one place on Hawaii where it actually snows from time to time.
Going back to your comment about the opening large picture of "meteors". Meteors don't radiate from a single point in the sky. They move in different directions.
This time-lapse photo seems to replicate the kind of sky I saw on the Big Island.
