Over the past three years, the general purpose CCD camera system developed at the Royal Greenwich Observatory (RGO) has been used to test, optimize and compare various types of CCD with further work being carried out on a variety of telescopes. The results of this work are described, dealing not only with the obvious features (such as noise and quantum efficiency), but the more subtle aspects such as low light level performance and temperature dependence. The astronomical relevance of the various factors is considered, and suggestions are made as to the suitability of each type of chip for various types of observation. Finally, the future of these TV format CCDs is considered in the light of the likely availability of much larger alternatives.
