Remarks: |
Kn 26 is a quadrupolar Planetary Nebula, which was assumed to be a
part of the Flying Dragon Nebula (Sh2-113/114) for a long time. Its real
nature as a PN was only revealed in recent years. A paper of the quadrupolar
nature of the PN can be found
here. The image above is a 200% version of a crop of the upper part of a 1x2 mosaic of Sh2-113/114 (Flying Dragon Nebula), see here. |

Bemerkungen: |
Kn26 ist ein quadrupolarer Planetarischer Nebel, von
dem bis vor kurzem angenommen wurde, dass er Teil des Flying Dragon Nebels
(Sh2-113/114) ist. Seine wahre Natur als PN wurde erst in den letzten Jahren
aufgedeckt. Eine Artikel über die quadrupolare Natur des PN ist
hier zu
