Abstract

Results are presented on the evaluation of the site for the Nordic Optical Telescope (NOT) at its site at the Roque de los Muchachos Observatory. Basic design features of the NOT are described together with the parameters that define image quality, with special consideration given to the role of atmospheric turbulence and the factors taken into account in the selection of the telescope site. Attention is given to the optical elements of the NOT and to its mechanical structure as well as to the thermal control of the telescope, the enclosure, and the ancillary instrumentation. Results from first observations at the NOT point to excellent observing conditions in terms of transparency and extinction stability as well as image quality.
