Some historical perspective…
M51—the Whirlpool Galaxy
Lord Rosse’s 72-inch
• Hooker the Lowes of past
• 1917
•Yoke mount blocks North Celestial Pole
•Still in use in spite of light pollution …
100-inch Hooker Telescope
… lights of LA, 1908 and …
Lights today … more on “light pollution” later.
•4th “largest in the world” built by Hale (40” Yerkes, 60-in and 100” Mt. Wilson)
•Split yoke allows access to NCP
•Funded by Carnegie Institution—Andrew Carnegie made his fortune in steel, his money lives on today
•A very difficult project—technology all new
• Why larger apertures?
200-inch Hale Telescope at Mt. Palomar
Schmidt Telescope
Used to photograph the whole sky in the Palomar Sky Survey (co-sponsored by the National Geographic Society). All of sky available online at the Space Telescope Science Institute as the “STScI Digitized Sky Survey” (link on WebCT Class Web Links page)
Has been used for most of the newly discovered extrasolar planets

Good public program, too.
