The stage and the plot

It is not often that one is allowed to look behind the scenes, as we have permitted you to do, showing pictures like Figs. 1 and 2 and telling the secret of removing the patchyness in Fig. 3. It may have been like walking on a stage in daytime. Nothing looks glamorous and the actors are still rehearsing. We hope, however, that the scenery appears safe and trustworthy for its final application and that it promises to be a worthy background for a great spectaculum. The plot will be presented in the version offered by the ESO/SERC atlas which, together with powerful measuring machines and computers, has opened new possibilities for staging the drama of the universe.
