<p>Mauna Kea is one of the best ground-based astronomy locations in the world.  The location is ideal because of its dark skies, good astronomical seeing, low humidity and position above the majority of the water vapor in the atmosphere, clean air, good weather and almost equatorial location.
</p><p>It also happens to host some spectacular sunsets.
