Scientific paper

Charge-coupled device frames of the Trifid nebula have been obtained with interference filters isolating the H-alpha and H-beta emission lines and the continuum near H-beta. The Balmer fluxes are compared with 4.875 GHz data, and a model of the nebula is discussed. By comparing Mathis' models (1972) of reflection nebulae with measurements of the intensity of the scattered continuum light, it is estimated that the 4693 A optical depth of M20 is approximately 1.5, and that the grains have a high albedo and a strongly forward-throwing phase function.
