DIRECT PHOTOGRAPHY OF PLANETARY NEBULAE IN THE DIRECTION OF THE GALACTIC CENTER
1988
In order to facilitate the identification and morphological description of planetary nebulae in the direction of the Galactic center, we present broad-band V, [O III] λ5007, and Hα images of 43 of these objects.In many cases the measured diameters of the nebulae agree well with those reported earlier by Perek, and the discrepancies that do exist may be attributed to measuring the diameters from images of very different photographic depths.
