Heao 2
Also called "Einstein observatory"
Equipped with a 58cm diameter telescope with a 3.3m focal length. The satellite
also contained five other instruments, 4 of which shared the use of the
telescope to make a variety of measurements of X-rays emitted by stellar
objects. The fifth instrument, independent of the telescope, measured
properties of X-rays beyond the telescope's energy range.
