| | Planetary nebula - definition of Planetary nebula in Encyclopedia |
| | In recent years, Hubble Space Telescope images have revealed many planetary nebulae to have extremely complex and varied morphologies. | | | The Hubble Space Telescope also showed that while many nebulae appear to have simple and regular structures from the ground, the very high optical resolution achievable by a telescope above the Earth's atmosphere reveals extremely complex morphologies. | | | Even the spherical ones can be amazingly complex. |

| | PLANETARY NEBULAE |
| | Planetary Nebulae are interesting objects for the deep-sky observer, offering a differing and challenging object for the study by the novice or advanced observer. | | | He is also interested in the historical understanding of these objects and has a special interest in "butterfly-like" bipolar planetaries. | | | Such objects would be more akin to the nova phenomena, or perhaps as a close binary systems. |

| | Precise Positions for the NGC/IC Planetary Nebulae |
| | One such set of objects needing improved positions is the class of planetary nebulae. | | | Despite publication in 1990 of the "Strasbourg-ESO Catalogue of Planetary Nebulae", many of the objects there are given with either imprecise or simply incorrect coordinates. | | | The GSC position clearly refers to the centroid of the nebula, but also obviously matches that of the central star within an arcsecond. |
