Paper Abstract

The existing Risley prism at the 4 meter telescope is described. This device compensates atmospheric dispersion up to 60 degrees from zenith for the visible range. Under converging light at f/8 and f/30 the axial performance is good and the field imagery is mostly dictated by the properties of the primary-secondary configuration.
