Palomar Observatory Prime Focus Tour

In the prime focus cage with Jesse Greenstein

Jesse Greenstein in the 200-inch prime focus cage.

Jesse Greenstein passed away in 2002. He joined the California Institute of Technology's Astronomy Department in 1948, just as Palomar was coming on line, and has spent many of the subsequent years using the 200-inch telescope to make spectroscopic observations of faint hot stars called white dwarfs.

Let us take you back to the summer of 1995, when Jesse, then 85, came back one more time to the primary focus cage of the Hale Telescope. He brought with him the trustworthy spectrograph he had used on countless observing nights. Even after so many years, he was still captivated by the atmosphere the observing dome. And his fascination spellbound everyone who had the incredible fortune to share this experience with him.
