How large should a telescope be to resolve stars w/ diffraction-limited optics at wavelength of 2 micrometers?
Regina asked:
Two identical stars are moving in a circular orbit around one another, with an orbital separation of 5 AU (Sec. 2.6) The system lies 150 light-years from Earth. If we happen to view the orbit head-on, how large a telescope would we need to resolve the stars, assuming diffraction-limited optics at a wavelength of 2 µm?

angle = 1.22 * wavelength / diameter
