The bright star in the upper right corner is Aljanah (Epsilon Cygni), third brightest star in the Cygnus constellation and part of the Northern cross asterism.
Nebulosity in the image is an ancient supernova remnant. Different parts of the remnant have acquired informal names over the years.
Arc like structure in the upper part of this image is called Eastern veil nebula (NGC 6992). Nebula in the lower part of the image is called Western veil nebula or the Witch's broom nebula (NGC 6960).
Title
“Witch’s Broom in the Void: NGC 6960 (Western Veil Nebula)”
Description
Beneath the wing of the celestial swan, I captured the ghostly filaments of the Western Veil Nebula (NGC 6960) — a breath of cosmic memory from a star that died thousands of years ago. This delicate lacework of ionized hydrogen and oxygen drifts across space, the remnant of a supernova whose shock-wave, sweeping through the interstellar medium, carved and illuminated the shell we now see.

The bright star 52 Cygni that appears embedded in the nebula is in fact a foreground star, giving us only the illusion of association.

Captured from the dark desert skies of the Desert Bloom Observatory (Bortle Class 2) on October 19, 20, 23, I used a Celestron NexStar EVO 9.25 f/10 and ZWO ASI2600MC PRO on a Sky-Watcher EQ-6R Pro mount, guided by a ZWO 30F4 Miniscope and ASI462 MC, with a ZWO ASIAir Plus controlling acquisition. A 2″ Optolong L-Pro multiband-pass filter was used to isolate emission detail, and exposures of 600 s each were stacked over 58 subs with DeepSkyStacker, then processed via PixInsight and Photoshop to bring out the fragile filament texture and subtle colour gradients.
The final frame reveals the interplay of glowing hydrogen (H-α) and doubly-ionised oxygen (O III) gas, sculpted by shock-fronts and cosmic currents into gossamer strands. It is a snapshot of stellar death and cosmic rebirth — a lament and a celebration, frozen in light.
May this image be a whisper from the universe: that even in destruction, there is beauty; even in silence, there is story.
C33 is the Eastern part of the Veil Nebula, part of the visible portion of the Cygnus Loop. It is a rapidly expanding supernova remnant.
Unfortunately my camera battery ran out after only 45 minutes so the image is quite noisy. I’ll have another go on the next clear night to try and improve it.

This is a stereo image of the Veil Nebula, using observations made by the NASA/ESA Hubble Space Telescope in 1997 and in 2015. If looked at them cross-eyed these two-dimensional images are then combined by the brain to give the perception of 3D depth. This illusion is created due to the movements of the filaments between the two observations.
The Cygnus Loop, located in the constellation of Cygnus the Swan, is a supernova remnant that occurred after a massive star exploded between 5,000 to 10,000 years ago. The loop is about 3 degrees in size and continues to expand. The data for this image was obtained on the 17th and 19th of Jul 2015. It consist of 67 X 5min exposures obtained with a Canon 60Da camera, Orion ED80T telescope, and a Celestron CGEM mount.
Edited Hubble Space Telescope image of part of the Cygnus Loop, which is essentially a circular nebula created by a supernova long ago. Inverted grayscale variant.
Original caption: While appearing as a delicate and light veil draped across the sky, this image from the NASA/ESA Hubble Space Telescope actually depicts a small section of the Cygnus supernova blast wave, located around 2400 light-years away. The name of the supernova remnant comes from its position in the northern constellation of Cygnus (The Swan), where it covers an area 36 times larger than the full moon. The original supernova explosion blasted apart a dying star about 20 times more massive than our Sun between 10 000 and 20 000 years ago. Since then, the remnant has expanded 60 light-years from its centre. The shockwave marks the outer edge of the supernova remnant and continues to expand at around 350 kilometres per second. The interaction of the ejected material and the low-density interstellar material swept up by the shockwave forms the distinctive veil-like structure seen in this image.
This image shows a small section of the Veil Nebula, as it was observed by the NASA/ESA Hubble Space Telescope. This section of the outer shell of the famous supernova remnant is in a region known as NGC 6960 or — more colloquially — the Witch’s Broom Nebula.

I took this image a few months ago, in October, while I took data for my school project. So it was something like a side product. This image was quite difficult to process as the CLS filter makes the stars reddish and too popped up. These days, I know how to reduce this negative impact during capturing the data, but I didn't before. So I think the result would be better if I took it today. But what can I do. At least I have this, and hopefully, I'll retake this object better in the future.
The Veil Nebula is a cloud of heated and ionized gas and dust in the constellation of Cygnus. It's a supernova remnant, which source supernova was a star 20 times more massive than the Sun, which exploded between 10,000 and 20,000 years ago.

L'anello del Cigno (Nebulosa Velo)
Il Cygnus Loop (sorgente radio W78 o Sharpless 103) o Nebulosa Velo (nota anche con le sigle del Catalogo Caldwell C33 e C34) è una vasta nebulosa diffusa visibile nella parte sudorientale della costellazione del Cigno.
La distanza della nebulosa non è nota con certezza; i dati del Far Ultraviolet Spectroscopic Explorer (FUSE) indicano una distanza di circa 1.470 anni luce.
Osservazione
Questo intricato sistema di nebulose è visibile con un binocolo con obiettivi da 80-90mm o con un piccolo telescopio a patto di avere un cielo buio, meglio ancora se si utilizza un filtro (UHC, OIII): si rivela meglio nelle foto a lunga posa (persino con una camera CCD occorrono diversi minuti).
L'oggetto apparirà formato da tre delicatissimi filamenti nebulosi, disposti a formare una sorta di circonferenza.
La parte più luminosa è quella più ad est, noto come NGC 6992.
Ingrandimenti sempre maggiori rivelano che ogni filamento è in realtà costituito da una rete di altri filamenti minori, sempre più sottili.
La scoperta di quest'oggetto fu ad opera di William Herschel, che nel 1784 la descrisse così: "Estesa; passa attraverso 52 Cygni... circa 2 gradi di lunghezza"; la parte occidentale della nebulosa ha una descrizione a sé: "Nebulosità ramificata... La parte seguente si divide in alcune correnti riunite ancora verso sud."
Caratteristiche
La nebulosa è un antico resto di supernova; la stella che ha originato quest'oggetto è esplosa diversi millenni fa.
Al momento dell'esplosione, la supernova sarebbe apparsa più luminosa di Venere nel cielo e visibile durante il giorno.
Ciò che ora è visibile sono dei debolissimi filamenti, ancora in espansione alla velocità di decine di km/s; nelle foto a lunga posa o con un CCD si distinguono diversi filamenti disposti in tre gruppi principali: il più ad ovest è quello di NGC 6960 (C34), in direzione della brillante stella 52 Cygni; il secondo, poco più ad est, è formato dalle nebulose NGC 6974 e NGC 6979, disposto con la concavità ad est come il precedente; l'ultimo, ad est, è formato dalle sezioni NGC 6992 (C33) e NGC 6995 (ai quali si aggiunge IC 1340), orientato in modo speculare rispetto agli altri due.
Questa parte è conosciuta pure come Nebulosa Rete (Inglese Network).
Si pensa che nel giro di pochi millenni questa "meraviglia" del cielo boreale scomparirà, perché ad una grande velocità di espansione corrisponde pure un elevato indice di dispersione della sua materia, che presto esaurirà la sua energia ricevuta durante l'esplosione, e si disperderà nel mezzo interstellare, "quasi" senza lasciare traccia.
Componenti della struttura in dettaglio
Nell'uso moderno, i nomi Nebulosa Velo, Nebulosa Cirri e Nebulosa Filamentaria si riferiscono generalmente a tutta la struttura visibile del residuo, o persino all'intero anello stesso.
La struttura è così grande che diversi numeri NGC sono stati assegnati a vari archi della nebulosa.
Ci sono tre componenti visive principali:
Il Velo Occidentale (noto anche come Caldwell 34), costituito da NGC 6960 (la "Scopa della Strega", Nebulosa Merletto, "Nebulosa Filamentaria") vicino alla stella in primo piano 52 Cygni;
Il Velo Orientale (noto anche come Caldwell 33), la cui area più luminosa è NGC 6992, che si estende più a sud in NGC 6995 (insieme a NGC 6992 nota anche come "Nebulosa Rete") e IC 1340;
Il Triangolo di Pickering (o Wisp triangolare di Pickering ), più luminoso sul bordo centro-settentrionale dell'anello, ma visibile nelle fotografie che proseguono verso la zona centrale dell'anello.
NGC 6974 e NGC 6979 sono nodi luminosi in una zona di nebulosità più debole sul bordo settentrionale tra NGC 6992 e il Triangolo di Pickering.

🌌 The Veil Nebula – Supernova Lace in Cygnus
📍 Back-yard hilltop, Spokane WA
️ Imaged over clear nights, June 23 – July 2 2025
Forged by a massive star that exploded some 12 000 years ago, the Veil Nebula is a sprawling super-nova remnant about 2 400 light-years away in the constellation Cygnus. Shock-front filaments of ionised hydrogen and oxygen weave through interstellar space, creating the delicate, ribbon-like structures that earn it the nickname “Cygnus Loop.”
