Die Cygnus-Schleife (Radioquelle W78 oder Sharpless 103) ist ein gro\u00dfer Supernova-\u00dcberrest (SNR) im Sternbild Cygnus, einem Emissionsnebel von fast 3 \u00b0 Durchmesser. Einige B\u00f6gen der Schleife, die allgemein als Schleiernebel oder Cirrus-Nebel bekannt sind, emittieren im sichtbaren elektromagnetischen Bereich.  Radio-, Infrarot- und R\u00f6ntgenbilder zeigen die komplette Schleife.
Visuelle Komponenten: der Schleiernebel

Der visuelle Teil der Cygnus-Schleife wird als Schleiernebel, auch Cirrus-Nebel oder Filament-Nebel genannt, bezeichnet. Mehrere Komponenten haben unterschiedliche Namen und Bezeichner,  einschlie\u00dflich des „Westlichen Schleiers“ oder „Hexenbesen“, des „\u00d6stlichen Schleiers“ und des Pickering-Dreiecks.

NGC 6960, der Westliche Schleier, ist der westliche Teil des \u00dcberrestes, auch bekannt als „Hexenbesen“, der sich bei J2000 RA 20h 45m 58.1s Dec + 30 \u00b0 35 ’43 „befindet. Als das westlichste NGC-Objekt im Nebel (zuerst in Rektaszension) wird seine Nummer manchmal als ein NGC-Identifizierer f\u00fcr den Nebel als Ganzes verwendet.

NGC 6992, NGC 6995 und IC 1340

Diese drei leuchtenden Bereiche bilden den \u00f6stlichen Schleier. NGC 6992 hat die Form einer Muschel am nord\u00f6stlichen Rand der Schleife bei J2000 RA 20h 56m 19,0s Dec + 31 \u00b0 44 ’34 „. NGC 6995 liegt weiter s\u00fcdlich bei J2000 RA 20h 57m 10.7s Dec + 31 \u00b0 14 ’07 „, und IC 1340 noch weiter s\u00fcdlich bei J2000 RA 20h 56m 12.0s Dec + 31 \u00b0 04′ 00“.<\/p>\n\n\n\n
