The appeal of CCDs is speed - getting instant results (like the visual observer) and supreme sensitivity. Although the CCD user may now have a permanent record to tweak at leisure, nothing compares to that initial view. When coupled to a simple prism innocuous points of starlight give up their secrets in real-time. A technique of using an objective prism before a reflecting telescope with a CCD detector to record stellar spectra is described and some results explained. The spectral sensitivity of the camera can be tested as a byproduct.
