Abstract

A Wolter type-I grazing incidence telescope is currently under construction at the University of Colorado, Boulder. The telescope mirrors were fabricated by machining on a lathe to approximately 1-2 arcminutes quality and ground and polished to improve their figures. Current measurement of the telescope's image quality gives a FWHM measurement of 44 arcseconds. We hope to achieve 5-10 arcsecond quality when completed.
