  1. 3-meter Shane Reflector at Lick Featured in Maxwell House ad a few years ago… Has been used for most of the newly discovered extrasolar planets

  2. McDonald Observatory (UT-Austin) 2.7-meter Good public program, too.

  3. McDonald Observatory’s Hobby-Eberly 9.2-meter Segmented mirror design

  4. Kitt Peak National Observatory Mayal 4-m Wynn • Near Tucson • Tax supported with other consortia, too • Nice public program • Tucson: good lighting McMath solar telescope

  5. Mayal 4-meter

  6. McMath solar telescope

  7. The MMT … Originally separate mirrors as shown here Whole building rotates Operated by the Smithsonian Institution, founded with funds from British scientist James Smithson, who bequeathed his fortune to America for the creation of an institute for the “increase and diffusion of knowledge.” Now looks like ….

  8. New MMT 6.5-meter

  9. Mauna Kea , Hawaii – Keck, Gemini, Suabaru, NASA, and others

  10. Canadian-French-Hawaiian 3.6-m Telescope

  11. Gemini (North) 8-m Telescope …

  12. 8-meter spin-cast mirror

  13. Twin Keck 10-m Telescopes

  14. European Southern Observatory (Chile) Why the shift to southern hemisphere? VLT 4 8-ms

  15. ESO 3.6-m

  16. Cerro Tololo nearby with this twin to Kitt Peak 4-m

  17. DuPont 2.5-m also there

  18. SOAR Telescope UNC-CH and others How’s it coming?...

  19. Russian 6-m • Nasmyth focus platforms • Problems: 17-ton mirror has thermal time constant of a few days; location based on politics. • Note alt-az mount
