阿贝尔行星状星云目录
关于阿贝尔星系星团目录，请见“阿贝尔星系团表”。阿贝尔行星状星云目录'是乔治·阿贝尔在1966年创建，包含86个被认为是行星状星云的天体。这些天体大约有一半是阿尔伯特·乔治·威尔逊搜集的，其馀的则由阿贝尔、罗伯特·乔治·哈灵顿和鲁道夫·闵可夫斯基搜集。这些天体是帕洛马山天文台为国家地理学会的帕洛玛天文台天空调查，使用48-英寸（1.2-米）的塞缪尔·奥斯钦望远镜，在1955年8月之前发现的的一部分[1][2]。其中的4个可以从以前的目录中更好地了解：阿贝尔50是NGC 6742，阿贝尔75是NGC 7076，阿贝尔37是IC 972，和阿贝尔81是IC 1454。另有四个后来被确认不是行星状星云：阿贝尔11(反射星云)、阿贝尔32(红板缺陷）、阿贝尔76（环星系 PGC 85185）和阿贝尔85（超新星残骸CTB 1，阿贝尔在1966年的论文中也注意到了此种可能）。另外三个也没有被列入斯特拉斯堡-ESO的银河行星状星云目录（SEC）：阿贝尔9、阿贝尔17（红板缺陷）和阿贝尔64[3]。目录上的天体最好用大口径望远镜（例如18-英寸（0.46-米））和 OIII双色滤光器来观察[4]。

, 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.

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.)
