About Hobby-Eberly Telescope
Located at McDonald Observatory at 2,024 m in West Texas. One of the first big segmented-mirror telescopes. Its structure tilts in azimuth only, a cost-saving design. The HETDEX survey is mapping 2 million galaxies to measure how fast the universe expanded at different epochs.
