| چکیده | ||
| A visual search has been made of four fields using United Kingdom 1.2m Schmidt Objective Prism plates with a reciprocal dispersion of 1 180 A/mm at HP. Such plate material is ideally suited to searches for emission-line galaxies. We present a catalogue of 53 emission-line objects, which comprises 45 galaxies, where individual HI1 regions are resolved in 16 bright galaxies; 8 are emission line stellar objects, including one low and one high redshift quasar. One field has a surface density of emission-line galaxies a factor of four higher than any of the other three fields, but the same density of galaxies with resolved HI1 regions. | ||
