Abstract. In order to study the spatio-kinematics of extended gaseous nebulae such as the HII regions associated with giant molecular clouds and planetary nebulae, we had designed and built an Imaging Fabry-Perot Spectrometer for the 1.2m Mt Abu Telescope. We describe here some of the significant scientific results that came out of these studies in the past one decade at Mt Abu.
