Special Behind the Scenes Engineering Tour: June 4

Date(s) - June 4, 2023
9:00 am - 2:30 pm


Come see the inner workings of the most productive observatory in history!

This special, behind-the-scenes tour concentrates on the mechanical, optical, and electrical details of our 60- & 100-inch reflector telescopes with demonstrations of their motion controls.  The new addition to the tour is of the Snow Solar Telescope which includes an explanation and demonstration of how it is set up and works.

The engineering that went into the 60- & 100-inch telescopes, both the biggest in the world for their time periods, represented the cutting edge of technology when they opened in 1908 and 1917 respectively.

The Snow Solar Telescope, the first instrument constructed on Mount Wilson, established the world’s first consistent scientific study of the physics of the sun and was also the largest instrument of its kind between 1905 and 1908.  It is still the oldest permanently installed working solar telescope in the Western Hemisphere.

Tickets: $75
