Abstract

An internally mounted shutter and a motor drive attachment for the plate-racking mechanism of a Littrow-Echelle Spectrograph are described. An associated electrical circuit provides automatic exposure control and predetermined automatic racking. Ease and exactness of operation are the primary benefits obtained.
