The spherical aberration in the HST primary mirror has generated considerable interest in restoration and deconvolution of WFPC images. The new WFPC 2 camera, which will be installed in HST in December 1993, should completely correct the aberration. Nonetheless, deconvolution may remain useful in removing optical artifacts such as Airy rings, diffraction spikes, and scattered light from WFPC 2 images. Herein we discuss the characteristics of both instruments, with emphasis on effects and problems which seem likely to impact restoration and deconvolution of these images. We begin with a brief summary of the layout and parameters of both instruments. We then examine problems which corrupt the PSF, effects which contribute noise to the images, and finally artifacts in the images which will complicate deconvolution.
