This view, shot from near the original University of Hawaii 88" telescope not long after sunset, spans 360° and shows nearly all of the observatories on Mauna Kea as of August 2014. Despite a 1st quarter moon, Keck II can be seen using a laser guide star for high-resolution imaging of the galactic core. The apparently curved path of the laser is due to the distorted view of the flat panorama.
From left to right, the observatories pictured are: UH88 - University of Hawaii 88" Telescope, UKIRT - United Kingdom Infrared Telescope, CSO - Caltech Submillimeter Observatory, JCMT - James Clerk Maxwell Telescope, SMA - Submillimeter Array, Subaru Observatory, Keck Observatories, IRTF - NASA Infrared Telescope Facility, CFHT - Canada-France-Hawaii Telescope, Gemini North Telescope.
