Gemini North & Mauna Kea

Gemini North LGS by moonlight

Nighttime image of the Gemini North Observatory, on the summit of Maunakea, during a Laser Guide Star (LGS) run, taken from the catwalk outside of the UH 2.2 meter telescope. LGS creates an “artificial star” which is used as a reference source for adaptive optics systems on Gemini instruments. The Canada-France-Hawaii Telescope (CFHT) is visible behind Gemini. This image was taken in preparation for two time-lapse movies which were recorded the following evening.

Gemini North Fish Eye LGS

Here is a "fish eye" image of the Gemini North observatory during a Laser Guide Star (LGS) run, taken from the catwalk around the outside of the UH 2.2 meter telescope. LGS creates an “artificial star” which is used as a reference source for adaptive optics systems on Gemini instruments. Directly behind the Gemini Observatory is the Canada-France-Hawaii Telescope; continuing counter clockwise is the NASA Infrared Telescope Facility, the double domes of the W. M. Keck Observatory, followed by the Subaru Telescope.

Moon over Gemini North Fish Eye View

The full moon rises over Gemini on the left and break lights from a passing car bathe the Canada France Hawaii Telescope in red light in this fish eye view from outside the observatories on Mauna Kea. In the distance you can just make out the forms of the Keck Observatory domes as well as the Subaru Observatory of Japan and the NASA Infrared Telescope Facility.
