Atlas Galaktischer Nebel. (Atlas of Galactic Nebulae). Part I: R.A. 0h00m - 12h00m; Decl. +90° - -33°.

This atlas presents reproductions of 435 diffuse objects recorded on the Palomar Observatory Sky Survey in the R.A.zone 0^h - 12^h and north of -33° declination, that have not been identified with galaxies or planetary nebulae. For a large number of objects the reproductions from the POSS are complemented by both wide-field images obtained with small astrographic cameras and by "close-up" exposures obtained at the f/8 Cassegrain foci of the 2.2 m telescopes at Calar Alto and La Silla.
