Abstract
The Magellan Project has as its goal the construction of an 8-m aperture optical telescope at Las Campanas, Chile, whose f/1.2 parabolic primary mirror is of borosilicate honeycomb type. The principal configuration of the telescope will be with Cassegrain focus at f/6.26; image sizes are expected to be of the order of 0.25 arcsec rms over the entire field, from 0.33 to 1.10 microns without refocus. An IR Cassegrain focus is planned at f/15, with a chopping secondary of low emissivity. Despite the fast primary-mirror f-ratio, spherical aberration will be acceptably low when chopping is accomplished via rotation of the mirror about its vertex.
