Gorenstein and Finoguenov (1994, SPIE 2280, 11) first suggested placing rotating modulation collimator (RMC) in front of a grazing-incidence optic to improve the angular resolution, while retaining the ability of focusing optics to reduce background. We have been studying this technique further, and suggest a way to improve the angular resolution of the Constellation-X HXT below 20 keV to a few arcsec FWHM. The configuration involves little disturbance to the mission plan and little loss of photons at higher energies.
