摘要
A low-dispersion objective-prism survey for low-redshift emission-line galaxies (ELGs) is being carried out by the University Complutense de Madrid with the Schmidt telescope at the German-Spanish Observatory of Calar Alto (Almeria, Spain). A 4 degrees full aperture prism, which provides a dispersion of 1950 Angstrom mm(-1), and IIIaF emulsion combination has been used to search for ELGs selected by the presence of H alpha emission in their spectra. Our survey has proved to be able to recover objects already found by similar surveys with different techniques and, what is more important, to discover new objects not previously cataloged. A compilation of descriptions and positions, along with finding charts when necessary, is presented for 160 extragalactic emission-line objects. This is the first list, which contains objects located in a region of the sky covering 270 deg(2) in 10 fields near alpha = 0(h) and delta = 20 degrees.
