Three Generations of Solar Cameras

These views of the Sun's full disk allow a comparison of three generations of solar cameras on McDonald Observatory's solar viewing system, from the original Overcash camera (smallest solar disk), to the upgrade to the first Semmes camera (middle disk), to the most recent Semmes camera upgrade (largest disk). The new camera's maximum resolution of the full solar disk has provided an astonishing improvement in size and clarity. (Kevin Mace/McDonald Observatory)
