Abstract. Observation of faint diffuse ultraviolet background radiation is a delicate undertaking, given the brightness of the
ultraviolet stars against which discrimination is essential. I demonstrate that the technique of tomography is unsuited to this
particular task.

1. Introduction
Most observational astronomy focuses on either the observa-
tion of point sources, or on observation of small extended
sources such as galaxies. Observation of true general diffuse
