We present a discussion of the various sources of FOC Point Spread Functions (PSFs), and the problems associated with their use. In particular, we highlight the time variability of the PSF halo structure and indicate some of the causes. We examine the usefulness of the PSF modelling software, TinyTim, and show that although this software creates visually similar images, these similarities are to a large extent superficial. We conclude by showing that the theoretical PSFs produced by TinyTim are inadequate for the restoration of high S/N FOC point source images. We also conclude that, because of 'breathing', there is a strong likelihood that empirical PSFs, whether pre-existing or specifically obtained, may not be sufficient either.
