High-Speed Direct Imaging Wood, P. R. ; Meatheringham, S. J. ; Dopita, M. A. ; Morgan, D. H. Abstract Images and fluxes of Magellanic Cloud planetary nebulae have been obtained with a time resolution of 1/60 s. The high time resolution was used to remove translational seeing effects. Angular diameters greater than 0arcsec.7 have been obtained for 20 Magellanic Cloud planetary nebulae, and fluxes in Hβ or [O III] λ5007 or both have been obtained for 80 nebulae. Masses have been derived for 18 nebulae from the angular diameters and Hβ fluxes. The ionized masses of typical Magellanic Cloud planetary nebulae increase with radius R roughly as R3/2 to R5/3 until R ≈ 0.1 pc; thereafter, the ionized mass has a maximum value of ≡0.5 M_sun;. Bolometric luminosities have been estimated for the central stars of those objects for which Hβ fluxes were obtained.
