Slitless Spectroscopy of Stars with Grating-Prism and Focal Reducer Techniques

E. H. Geyer
1979 International Astronomical Union Colloquium  
AbstractA slitless field spectrograph for Cassegrain telescopes has been designed. It is based on the focal reducer optical arrangement and grating prisms. Together with the "multiple diaphragm method" not only a gain in limiting magnitude of 3 to 4 magnitudes has been achieved, but also other drawbacks of the classical objective prism camera are avoided.
