Attention is called to the long-known, but often ignored, property of a grating spectrograph to (de)magnify the slit width and length by different amounts. As an illustration, the "grating magnification" r is given as a function of grating tilt for the Ritchey-Chrétien spectrograph of the CTIO 4-meter telescope; we find that for large grating tilts the… CONTINUE READING
