Discovery of New Faint Northern Galactic Planetary Nebulae. (2012). Revista Mexicana De Astronomía Y Astrofísica, 48(2), 223-233. https://astronomia.unam.mx/journals/rmxaa/article/view/2012rmxaa..48..223a
Abstract
We present the discovery of 6 nebular objects made by amateur astronomers. Four of these discoveries are clearly planetary nebulae (PNe), one is a possible PN, and another is a likely H II region. The bipolar nebula Ou4 presents the largest angular extent ever found: over one degree on the sky! We consider various scenarios that could explain such a nebula. Ou4 could be one of the nearest PNe known, though its possible PN nature will need confirmation.Similar Articles
