The classification systems and list N1, declination ⪉ -27.5, galactic latitude ⪆ +20 . Smith, M. G. ; Aguirre, C. ; Zemelman, M. Abstract A list is presented of 116 faint emission4ine objects which are generally similar in physical properties to those found by Markarian. These objects were discovered with a low-dispersion, full-aperture objective prism mounted on the 61 cm Curtis Schmidt telescope; emission lines can be distinguished with remarkable clarity in the Schmidt spectra. The region of sky surveyed for this first list is a relatively low-latitude section of the north galactic hemisphere covering about 700 square degrees and containing several nearby clusters of galaxies; being of low latitude, this region is representative of the more difficult areas to survey. Identifications include 111 galaxies, two possible QSOs, two planetary nebulae, and one dwarf nova. Seyfert galaxies are most likely to be found from a short list of 18 objects given in the final section of the paper. Classification systems for the forms of the objective-prism spectra and for the optical properties of the objects themselves are presented and discussed.
