The John W. Evans Solar Facility (ESF) is two telescopes in one,
both tracking the solar cycle. A 16" coronagraphic telescope maps magnetic changes
in the Sun's outer atmosphere. A special set of 12" coelostat optics "squints" so
the Sun appears as a pinpoint, allowing an "apples and apples" comparison with the
cycles of distant stars.
