Abstract

Two-dimensional long slit AAT IPCS spectra of IC 418 (in the 3400–4400 A wavelength region) show faint extensions in the [O II] 3726, 3729 A and Hγ emission lines out to at least 60 arcsec south and 50 arcsec north of the central star, compared to the angular radius of only 6 arcsec for the bright nebula.
