Abstract

Description and the performance are given of a reflecting telescope and accessory optics used to feed a Lyot Hα tunable filter, and then to obtain monochromatic images near the Hα wavelength. The instrumentation has been designed for coronal photography to be taken inside and outside the line during a total eclipse.
