Catalogue of Bright Nebulae.

Abstract

A catalogue of bright nebulae has been compiled from a study of the red and blue prints of the Ivational Geographic-Palomar Observatory Sky A tias. This catalogue contains itions both equatorial and galactic, for the centers of the nebulosities, values of their largest dimensions in minutes of arc and of their areas in square degrees, and estimates of their colors and surface brightness on an arbitrary scale. Total areas of the nebulae are tabulated as a function of galactic latitude for three different color classes.
