Scientific paper

Much of the scientific utility of narrow band imaging of nebulae lies in the study of stratification and structural variations among emission lines that trace regions of different density, temperature, and radiation environment. As such, these studies are not as seriously affected as some by the compromised optical performance of HST, so long as adequate signal to noise is obtained to allow reliable deconvolution of the structure present. The spatial resolution of the HST provides access to physically important scales associated with many gasdynamic and radiative processes in the ISM. In the present proposal, we request time to extend our studies of the cooling and recombining flows behind radiative shocks using images of three additional fields that cover a significant cross section of the conditions within the Cygnus Loop. We also request time to continue our study of the stellar jet and "ladder" discovered to the north of Eta Carinae, to study the interaction of the stellar wind and radiation field with a shell of gas in NGC 6888. It is proposed to observe the subarcsecond structure of the planetary nebula NGC 7027 in order to extend the studies of condensation lifetimes and interactions with the ISM.
