| 566 Stereoskopia || 1905 QO || The Blink comparator, formerly known as "stereo-comparator", is an apparatus used to find differences between two photographs of the night sky by rapidly "blinking" back and forth between the two. In 1902, this asteroid was the first to be discovered by this method using photographic plates taken in 1899. The asteroid was named by the inventor of the Blink comparator, Carl Pulfrich (1858–1927). ||
