The normal incidence soft x-ray, = 63.5å, telescope of 1991

Modifications to our multilayer coated normal incidence telescope for λ = 63.5Å since its last flight in 1989 are described. The purpose of the changes was to increase the photon flux of the detector by increasing the mirror reflectivity, area and uniformity and by the use of light blocking filters with higher x-ray transmission. First results from the 1991 launch of the telescope are described.
