Description
Observations of three post-Main-Sequence nebulae, taken with an
intermediate dispersion spectrograph mounted on the 2.5 m Isaac Newton
Telescope (La Palma, Spain), are presented. The results reveal evidence
for high-velocity outflows of about 100 km/s in the primary shells, and
very much greater velocities in the cores, while in one unique source,
there also appears to be evidence for a core WC binary.
