On a beautifully sunny late April day in 1963, my family made its first visit to Kitt Peak National Observatory. As we stood inside the massive interior of the McMath Solar Telescope, we saw the Sun’s rays reflected off a high “coelostat” mirror to the main mirror far below us, and then back to a smaller diagonal that sent the beam to an observing room beneath us.
