Dressed in parkas and knit caps, the three volunteers lug crates of power tools and spooled wire into the gleaming mountaintop edifice that some have called astronomys Sistine Chapel and immediately start tinkering.
In 1904, workers installed the first telescope at the still uncompleted Mt. Wilson Observatory. For much of the 20th century, astronomers with names like Hale and Hubble used it and the new telescopes it sprouted the 100-inch reflector and three solar telescopes followed the initial 60-incher as a figurative launch pad for exploration that changed our understanding of the cosmos.
Gradually, though, financial support waned along with the observatorys cutting-edge status, and for the last 20 years its telescopes, still impressive by any standard, rely on the kind attention of a small volunteer team of retired space industry electrical engineers, most now in their 70s and 80s.
So it is that on a morning when parts of the San Gabriels are topped with snow, Kenneth Evans is on a ladder, his head lamp fixed on a new sensor switch for a 100-inch reflecting telescope that dominated the world of astronomy for more than three decades.

The amount of effort required to retro-fit a 100+ year old telescope is amazing, especially the power aspects. Ken is a master in this effort. They all deserve the recognition given in this article - and more!
Rock on, boys!

(966 posts)It was the complete story of the building of the 200 inch Hale telescope in 1934.
The book was fascinating from designing the mirror to selecting Pyrex glass for the mirror blank, to building a special rail car to transport the (Giant Eye) as the news media called it, from Corning New York to Cal Tech in Pasadena California where the grinding of the mirror to a perfect parabolic shape would take place.
With the reading of that book I was hooked, and I have been an amateur astronomer ever since.
