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° full aperture prism, which provides a dispersion of 1950 Å mm^-1, and IIIaF emulsion combination has been used to search for ELGs selected by the presence of H_α 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 α = 0^h and δ = 20°.

It is our great pleasure to thank the friendly assistance and observing support received from the Calar Alto Observatory staff and specially from Kurt Birkle. We also express our thanks to our colleagues at the Departamento de Astrofísica for their encouraging support and many fruitful discussions. The finding charts were copied from the Palomar Observatory Sky Survey prints at the Observatorio Astronómico de Madrid with the help of Gerardo del Río. We are greatly indebted to José Luis Casero of ESA-IUE Villafranca Satellite Tracking Station for the finding charts plate composition and to Osear Alonso for the elaboration of Figs. l and 2 and for his very constructive comments. This research has made use of the NASA/ IPAC Extragalac­tic Database ( NEO) which is operated by the JET Propulsion Laboratory, Caltech, under contract with the National Aero­nautics and Space Administration. This work was supported in part by the Spanish "Programa Sectorial de Promoción General del Conocimiento" under grant PB89-124.
