We had an opportunity to take a tour of the Theodor Jacobsen Observatory, located on the campus of the University Of Washington.
From the University website: Built in 1895, the Observatory with its 120-year old, 6-inch refracting telescope is still offering celestial views of the wonders of the Universe.
The telescope and dome have been restored. Sadly - there's too much light pollution to really use this telescope too much anymore - but the Seattle Astronomical Society does have viewing nights there. Click this link for more info: TJO Evening Public Talks
After attending a presentation by the University staff about the Sun, we followed the sign on the stairs to the top of the dome. (No more than 12 at a time, though!):
This telescope was built before electricity was readily available. There is a clock mechanism that moves the telescope to track celestial objects. You crank it up on the side - note the weights down below to keep it moving:
All in all - a great night.
