Mauna Kea Summit Ridge seen from the Northeast
The Gemini telescope, on the right, is presently being built.
Adjacent and to the left of the Gemini telescope is the UH 2.2-meter
telescope. The extension at the top of the dome of this telescope
houses a crane. This crane is used to bring the aluminizing tank to
the telescope when the primary mirror is aluminized. (In most other
telescopes, the mirror is transported to the aluminizing tank.) In
the distance is the dormant volcano Hualalai.
