The First 50 Years at Palomar, 1949–1999 Another View: Instruments, Spectroscopy and Spectrophotometry and the Infrared

We review the research on a wide variety of topics using data obtained with the 200-inch Hale telescope. Using state-of-the-art spectrographs, photometers, spectrometers and infrared detectors, the Palomar astronomers investigated the spectra of stars, interstellar matter, AGNs and quasars in great detail. Spectral resolutions ranged from 1000 A for broad-band photometry to 0.04 A using interferometric techniques.
