Outline of Final Research Achievements

To search of star forming regions around nearby spiral galaxies, we prepared large narrow-band filters for emission lines generated from ionized hydrogen (Halpha) and ionized oxygen ([OIII]) installed the 105cm Schmidt telescope and the Kiso Wide Field Camera (= KWFC) at Kiso Observatory, University of Tokyo. From observations of spectroscopic standard stars and nearby spiral galaxy, I obtained measurement errors of decisions of magnitude zero-points and limiting surface brightnesses in narrow-band observations. I also obtained Halpha emission line image of M100 from narrow band image and continuum one made from broad band them, and found 28 Halpha sources in this region.
