ホビー・エバリー望遠鏡
1. Hobby-Eberly TelescopeThe Hobby-Eberly Telescope is a 9.2-meter (30-foot) aperture telescope located at the McDonald Observatory. It combines a number of features that differentiate it from most telescope designs, resulting in greatly lowered construction costs. For instance, the telescope mirror itself does not move to track the night sky; instead, the instruments at the focus are moved across the face of the unmoving mirror, allowing a single target to be tracked for up to two hours.
