The Case low-dispersion northern sky survey. I.
Abstract
Positions, estimated magnitudes, and finding charts (when necessary) are provided for 71 blue and/or emission-line galaxies, probable H II regions in four galaxies, 59 blue and/or emission-line stellar objects including QSO candidates, and 28 known and probable blue stars in the region where alpha is between 8h45m and 10h50m and delta is between +29.0 deg and 33.0 deg (1950). The objects, whose blue magnitudes range from 13 to 18, were identified on low-dispersion, objective-prism plates taken with the Burrell Schmidt telescope at Kitt Peak and are the initial fruits of a survey that will ultimately cover the northern sky within the boundaries where b and delta are both greater than +30 deg.
