  FUSE high resolution spectra of two PG1159 type central stars (K1-16 and NGC
7094) have revealed an unexpected iron deficiency of at least 1 or 2 dex (Miksa
et al. 2002). Here we present early results of FUSE spectroscopy of the CSPN
Abell 78. It is shown that iron is strongly deficient in this star, too.
