The Gemini Observatory consists of twin 8.1-meter diameter optical/infrared telescopes located on two of the best observing sites on the planet. From their locations on mountains in Hawai'i and Chile, Gemini Observatory's telescopes can collectively access the entire sky.

Gemini is operated by a partnership of five countries including the United States, Canada, Brazil, Argentina and Chile. Any astronomer in these countries can apply for time on Gemini, which is allocated in proportion to each partner's financial stake.

Use with LGS

The Gemini Mauna Kea Laser Guide Star (LGS) System is designed to extend the use of ALTAIR for targets for which a bright natural guide star (NGS) is unavailable for adaptive optics correction. In general, LGS AO delivers somewhat lower Strehls than NGS AO, but it allows the use of fainter natural guide stars (because the guide star is used only for tip/tilt correction) and thus is possible over a much larger fraction of the sky than NGS AO.
