Hamburg Schmidt-camera survey of faint planetary nebulae. Cygnus-Perseus region.
Abstract
The third part of the H Schmidt-camera survey of faint planetary nebulae contains the remaining area in the northern Milky Way 1 70 -146 , b + 100. 32 new planetary nebulae were classified -6 of which are identical with the objects discovered very recently by Kazarjan and Parsamjan - and measured on the Palomar Sky Atlas. For the new nebulae the concentration towards the galactic equator was found higher than of those already known. Th the Appendix three compact small H TI regions have been described. Key words: planetary nebulae - galactic structure
