Russell Porter, trained as an architect, joined the Palomar development team in 1928 to help with the observatory's engineering and design. Among his many achievements are detailed drawings of the Hale Telescope like this one. Carolyn Heffner, a Palomar night operations supervisor, said that the drawings are so good that she sometimes goes down to the lower levels of the dome where several of his sketches are hung to better understand how the telescope was put together.

This photo shows a pool room in the 200-inch dome, where astronomers used to go and relax when they were not observing. Greg Van Idsinga, an electronic technician at Palomar who has worked at the observatory for 43 years, says the pool room does not get as much use as it did in its early days. "The only thing aging about Palomar is the pool room," he says.
