The optical variants of these devices come in reflecting and refracting types, named for Newton and Galileo respectively.
A technique utilizing satellites that lets two or more of these devices work as a single large one relies on an atomic clock, usually a hydrogen maser, and is based on Roger Jennison's closure-phase techniques. Very Long Baseline Interferometry is one strategy for using these devices, one type of which is named for Schmidt and Cassegrain. The optical variants of these devices come in reflecting and refracting types, named for Newton and Galileo respectively. For 10 points, name these devices that form magnified images of celestial objects.
