Tom Hagen, Ace Tour Guide in Action!
Tom Hagen points out key features of Tower #2's coelostat, a 22" flat mirror and associated hardware that acts as the primary for this tower's instrument. The coelostat tracks the sun over the course of the day, reflecting raw sunlight on to three other mirrors and a lens, which channels the beam into a spectroheliograph. Tower #2's entire instrument system was nearly functional at the time of the tour.
Tom is a member of both the McMath-Hulbert Astronomical Society and the Oakland Astronomy Club. Tom has been spending many Sundays, often late into the night, at MHSO working towards restoring the historic site. "It's a real labor of love" says Tom.
