Abstract

We have undertaken a survey of planetary nebula (PN) expansion velocities in the [O III] λ5007 line in Local Group galaxies visible from the OAN-SPM, Mexico using the Manchester Echelle Spectrograph (MES; Meaburn et al. 2003) on the 2.1-meter telescope. The instrumental profile has a velocity width of 11.5 km s-1 (2.7 pixel FWHM), and the nebular line profiles are always resolved.
