Yerkes : Yerkes Observatory was the first step that George Hale took on the way to building the 200” telescope at Mount Palomar.  The main instrument is a 40” diameter telescope which today is still the largest operating refracting telescope in the world.  Except for the black & white photos, the rest of the photos in this gallery were taken in the early 90’s.

Mount Wilson Observatory : The next step for George Hale after building and managing Yerkes Observatory was to head to Pasadena CA in search of better skies to continue his astro physics studies.  As with most astronomers today he was looking for better air and more light.  It seems we are always looking for more light.  Mount Wilson, in the hills just north of Pasadena, provided Hale with more stable air and more clear nights to make his observations than he found in southern Wisconsin.  The Mount Wilson Observatory (MWO) became a world leading observatory and produced significant work for almost ten decades.  Except for the black & white photos, the rest of the photos in this gallery were taken in the early 90’s.

Palomar 200 inch Telescope : The 200” Hale telescope is the forth in a series of large telescopes that George Hale envisioned and was the driving force that made those projects successful.  He built the largest telescope in the world four times in a row!  At the start of this project in 1938 there were several major inventions required to even make a telescope of this size possible.  There are several books that chronicle the fascinating story of the construction of this telescope that are worth reading.  This is a selection of photos from two visits to Palomar in the early 90’s.  On the second visit I was privileged to spend three nights with astronomers as they worked on two projects related to proper motion of stars and a quasar hunt.

Palomar 48" Schmidt Camera : The 48” Oschin Schmidt  Camera is located on the grounds of Mount Palomar Observatory.  This instrument is only designed to take photos with no visual use possible.  It was started in 1938 but was not completed until 1948 due to the interruption from World War 2.  The 20 foot long tube and fork mounting weigh about 12 tons.  The instrument has a 48 inch diameter corrector lens in front, and a 72 inches inch diameter mirror in the back.  This combination provides a 120 inch (3 meter) focal length at f/2.5.  This is the largest Schmidt Camera in the World and it’s used to map the sky and find objects for other telescopes to study.  These photos were taken in 1992.
