Abstract
We present observations of three post-Main-Sequence nebulae taken with an intermediate despersion spectrograph mounted on the 2.5 m Isaac Newton Telescope (La Palma, Spain). Our results reveal evidence for high-velocity outflows of ∼ 102 km s−1 in the primary shells, and very much greater velocities in the cores, while in one unique souce there also appears to be evidence for a core WC binary.
