Short exposure 4 m prime focus plates taken with interference filters centered on blue continuum 4765 A, He II 4686 line, red continuum 6485 A, and H-alpha line have been used to study the light distribution within R136a. R136a contains a bright component and several fainter components superposed on an extended background. The brightest component, unresolved under sub-arcsec seeing condition, contributes about 37 percent of the total light from a 3 in. diameter aperture. Combining the optical and UV information, it is found that this brightest component R136a1 may be a single star with a mass of approximately 750 solar masses with a brightness of six HD 93129A or 20 O3 V stars, or it could be a cluster of such stars. In either case, R136a1 supplies no more than one-half of the ionization of the 30 Doradus nebula.
