By "easy" I don't mean easy to see, at least not in a small telescope. (I highly recommend an OIII filter, no matter what size scope you're using.)

, As the National Geographic Society-Palomar Observatory Sky Survey1 nears completion, preliminary lists are being compiled of some of the many new objects discovered. These lists include more than seventy new planetary nebulae and about a dozen star clusters that are believed to be globular.

Among the many new objects discovered on the photographs taken for the National Geographic Society-Palomar Observatory Sky Survey, eighty-six provisionally classed as planetary nebulae are described here. A. G. Wilson first identified about half of these objects; the rest were found by R. G. Harrington, R. Minkowski, and the writer. Since the publication of a preliminary finding list of seventy-three of these nebulae (Abell 1955), several more have been discovered; more reliable positions and other data for all of the nebulae are given here. The present list of eighty-six objects includes two entries in the Index Catalogue that were not there-identified as planetary nebulae, five objects in a list of new planetary nebulae that was subsequently published by Kohoutek (1962b, 1963), and at least one object that is a radio source and thus which may be a supernova remnant. All eighty-six objects are included in this investigation, however, and are described as "planetary nebulae," with cognizance of the fact that one or two of them may be improperly identified.

The selection of the objects populating this catalogue is mainly based on an observational programme, and a verification programme consisting of spectroscopic observations for all suspected planetary nebulae, assuming that a planetary nebula has a spectral signature which can easy be recognised. For the present catalogue, a list of 1820 objects, each of them called at least once a planetary nebula, have been inspected; 1143 of them have been classified as true or probable planetary nebulae; 347 objects, which status is still unclear, were classified among the "possible" planetary nebulae. Finally, 330 objects have been rejected. Part I: A. Explanation of the catalogue. B. Tables. C. References of papers containing 20 objects or more. D. Finding charts. Part II: The catalogue.
