Image (log stretch) of the preplanetary nebula IRAS 19475+3119 made using exposures taken with the HST ACS through the ﹩\mathrm{F}\,435\mathrm{W}\,﹩ filter. The maximum (black) and minimum (white) intensities of the gray scale are ﹩6.87\times 10^{-13}﹩ and ﹩4.33\times 10^{-17}﹩ ergs s−1 cm−2 Å−1 arcsec−2, respectively. Lobe d appears to be composite, with a minor lobe, d’. A smooth, round halo surrounds the lobes.
