title: Far-ultraviolet photography of orion: interstellar dust.
abstract: Wide-angle photography of Barnard's Loop Nebula suggests that the nebular emission is much less intense in the 1230- to 2100-angstrom spectral region than in the 2200- to 3200-angstrom near-ultraviolet region. This contrast may be due to differences in the absorption or scattering properties of the interstellar grains in these two wavelength regions.
