Telescopic camera captures its first solar eclipse

In 1966, NCAR researcher Gordon Newkirk designed an improved coronal camera to observe the Sun's outermost layer. Newkirk and colleagues deployed it on an eclipse expedition in Bolivia that year. With three plates to block interference from the solar disk, the instrument opened a new chapter in eclipse observing. Researchers kept the Newkirk camera in use for almost 30 years to periodically observe the Sun's corona.
