An 85-foot Telescope on the Move

Moving the 85-2 telescope farther along the road separating it from its partner, the 85-1, otherwise known as the Howard E. Tatel Telescope. The two telescopes formed the NRAO’s first array, the Green Bank Interferometer. Changing the distance between the 85-footers changed the resolution of the array’s combined view: farther equals higher resolution.
