Abstract

Most of the instruments of the Apollo Telescope Mount are satellite-borne because they observe in regions of the electromag-netic spectrum where the telluric atmosphere is opaque. For the coronagraph of the High Altitude Observatory, observing in visible light, this is not so. The structure of the solar corona is obscured from ground-based observations by scattered light in the earth's atmosphere, and observations from space are required to reduce this scattered light to a level which is negligible with respect to the brightness of the outer solar corona.
