De aspecto caótico, estos filamentos de gases convulsionados y resplandecientes, visibles en el cielo terrestre en dirección de la constelación del Cisne, forman parte de la nebulosa del Velo

Considerada en conjunto, la nebulosa del Velo es el enorme remanente de una supernova es decir, una nube en expansión originada por la muerte explosiva de una estrella masiva.

La luz de la explosión de la supernova original probablemente llegó a la Tierra hace más de 5 000 años. Expulsadas violentamente por el cataclismo, las ondas de choque se propagaron por el medio interestelar barriendo e ionizando toda la materia que encontró a su paso.

Chaotic in appearance, these filaments of convulsed and glowing gases, visible in the terrestrial sky in the direction of the constellation Cygnus, are part of the Veil Nebula.

Taken together, the Veil Nebula is the enormous remnant of a supernova, that is, an expanding cloud caused by the explosive death of a massive star.

Light from the original supernova explosion probably reached Earth more than 5,000 years ago. Violently ejected by the cataclysm, the shock waves propagated through the interstellar medium, sweeping away and ionizing all matter in their path.

Located in constellation Orion and at about 6,500 light years from us, NGC 2174 is an emission nebula, rich in hydrogen and oxygen, with an apparent diameter slightly larger than the full moon. Within it, there is a loose star cluster, NGC 2175, with recently born stars. The stellar winds and radiation from these high energetic regions carve the nebula, yielding these beautiful structures.

The sky was clear last night so I pointed the 'scope at a ghost -- that's what Halloween is all about. This is the Ghost of Cassiopeia through an Ha filter. I collected about 8 hr of data last night and added it to Ha data collected in 2022. I had 17 hr of data in total and the image was made from the best 12 hr, as rated by DeepSkyStacker.

IC 59 is the upper-left part of the dust cloud, IC 63 is the "ghost" in the middle, and the lower lump/bump doesn't have a name, so I think we should call it IC Nothing. Below are a few fun facts about this little grouping.

IC 59 and IC 63 are a combination of faint, arc-shaped emission and reflection nebulae, located about 600 light-years away in the constellation Cassiopeia. Together they are approximately 10 light-years across. IC 63 is known as the Ghost of Cassiopeia.

The brightest star in the image is Gamma Cassiopeiae, which is 19 times more massive, 65,000 times brighter, and spins 200 times faster than our sun. The radiation from Gamma Cass is so intense that it affects the IC 63/59 gas/dust cloud several light years away.

A Hydrogen-Alpha + Oxygen III + Sulphur II Narrowband widefield image of the Cygnus Wall. The North America Nebula (NGC 7000 or Caldwell 20) is an emission nebula in the constellation Cygnus, close to the star Deneb. The remarkable shape of the nebula resembles that of the continent of North America, complete with a prominent Gulf of Mexico.

The Cygnus Wall:

The Cygnus Wall is a term for the "Mexico and Central America part" of the North America Nebula. The Cygnus Wall has the most concentrated star formation in the nebula. The North America Nebula and the nearby Pelican Nebula, (IC 5070) are in fact parts of the same interstellar cloud of ionized hydrogen (H II region). The nebula complex is estimated to be about 1,800 light-years from Earth.

The incandescence of the Eagle Nebula is laced with intricate dark lanes, globules, and huge clouds of dust which shroud ongoing star formation from direct view. The most prominent dark structures are the so-called “Pillars of Creation”, three long fingers of gas and dark dust nearly ten light years long. The Pillars are a field laboratory for the study of star formation and have been examined intensely by astronomers at visible, infrared, and ultraviolet wavelengths. Within the Pillars are much smaller, warmer, and denser regions called evaporating gaseous globules (EGGs), some of which contain just a few solar masses. The EGGs are ground zero for star formation, though it’s difficult to catch these new stars in the act of igniting because they remain obscured by cloaks of dark dust. EGGs located near bright stars are elongated by winds of light and charged particles into what look like schools of celestial tadpoles.

The stars within the Eagle Nebula appear to be in an intermediate state. Stars within the Pillars and other dusty regions remain obscured, while a cluster of some 400 new stars clearly appears in a more transparent section of the nebula. The largest of these stars has a mass some 80 times that of our Sun and the luminosity of perhaps a million Suns. The cluster formed just 2 to 5 million years ago. The nebula itself is only slightly older.

The light we see from the Eagle Nebula and its associated stars left some 7,000 years ago, but some astronomers suspect the Pillars of Creation may have already been obliterated when a massive young star within the nebula detonated as a supernova. The Spitzer Space Telescope detected evidence of a patch of hot gas near the Pillars which may have been caused by such an event about 8,000 years ago. Information from our e-book The Armchair Astronomer cosmicpursuits.com/e-books/armchair-astronomer-volume-1-n...

Two neighbouring nebulae in the northern constellation of Auriga illustrate different outcomes for an ageing star. The nebula on the right, #221 in the Sharpless catalog, is a supernova remnant, created when a star exploded catastrophically. The nebula on the left, Sharpless 216, is a planetary nebula created when an ageing star expelled its outer layers.

This image is an integration of a total of 22 hours of data captured with a William Optics Redcat51 telescope and ASI2600MCPro camera. An Optolong L-eXtreme filter was used and all post-processing was carried out in PixInsight.

This cluster (M5 or NGC 5904) is too big for the setup I've been using a lot recently, so I shot it with the Hyperstar at a focal length of 535 mm instead of the 0.63x reducer at 1530 mm. I just got a set of 2" Optolong LRGB filters from Starizona to use with the Hyperstar and Atik 414-EX camera, and this was my first target.

I think I've made some progress

About 20 years ago I saw Andromeda for the first time in one of my first photographs at night. Since then, it has been a big dream of mine to be able to photograph her "in large". And this dream has finally come true :-)

After nine nightly imaging sessions and many processing sessions last September, I finally finished this beautiful deep-sky image.

The Andromeda Galaxy is a majestic spiral galaxy located approximately 2.5 million light-years away from Earth. Andromeda is on a collision course with the Milky Way, and the two galaxies are expected to merge in about 4 billion years, forming a new galaxy often referred to as "Milkomeda." Andromeda is home to over one trillion stars, more than twice the number in the Milky Way. Remarkably, it was one of the first galaxies observed using a telescope in the 17th century, and its light takes over two million years to reach us, offering a glimpse into the distant cosmic past.

NGC 7331 is the prominent spiral galaxy to the right in this image. The galaxy is a bit under 50 million light years away, and it shows a complex structure of dust lanes, along with some H II regions in its spiral arms and disks. These appear as pink dots within the galaxy in this image. The left half of the image is the Deer Lick Group of galaxies. This is not a true group of galaxies -- they are too far apart from each other to be gravitationally bound in a group. They just happen to all lie in the same direction on the sky.

These galaxies pass directly overhead from my location.

The M78 nebulae complex in Orion. This is an LRGB image taken on a QHY163M monochrome camera using Optolong filters. The scope was a William Optics FLT110 with Flat4 mounted on a Skywatcher AZ EQ6-GT. Image sequencing was managed via Sequence Generator Pro and PHD2, auto-focus was controlled with a Lakeside Astro focus motor. Over 5 hours of data, in 2 minute subs, in each of the L, R, G and B channels. All post-processing was done in PixInsight.

Taken from Prachinburi, Thailand.

The Eagle Nebula at top (aka M16) and the Swan Nebula (aka M17), straddling the Serpens-Sagittarius border. The star cluster below M17 is M18, while the small cluster above M16 is Trumpler 32. The Swan Nebula is also called the Omega or the Checkmark Nebula. The Eagle Nebula contains the dark towers called the Pillars of Creation made famous in the Hubble images.

This is a blend of a stack of 9 x 8-minutes at ISO 3200 through the Optolong L-eNhance dual-band nebula filter, with a stack of 6 x 5-minutes at ISO 800 with no filter, all through the SharpStar 94mm refractor at f/4.4 and with the Canon EOS Ra camera. I used the AstroHutech filter drawer/adapter to aid swapping out the filter. Autoguiding was with the MGEN3 stand-alone autoguider. All images stacked, aligned and blended with Photoshop.

I shot this set on June 14/15 on one short night a week before summer solstice from home at latitude 51° N, so the sky was never fully dark, making colour correction a challenge, resulting in a somewhat monochromatic look. In addition, the time to shoot was only 2 hours or so, limiting the number of sub-frames. Plus this field is low in the south from my latitude.

Also taken on a very warm +24° C night for my western Canadian location, all without darks or LENR thermal noise reduction, as a test, just with frame-to-frame dithering to reduce thermal speckling which was abundant on the filtered high-ISO shots. Stacking with a median stack mode eliminated most, though not all, of the speckling.

This is a rather faint supernova remnant in the constellation of Monoceros. This image is an integration of 19 hours of dual narrowband data taken with a William Optics FLT110 telescope, a QHY268C camera and an Optolong L-Ultimate filter. I also took another 10 hours of luminance data.

All post-processing was carried out in PixInsight.

Aquí comparto una foto de campo amplio (más o menos)...

Se trata de NGC 6960 y NGC 6992 o lo que es lo mismo las Nebulosas del Velo Estre y del Oeste.

La parte de arriba según se mira la foto es NGC 6960, la Nebulosa del Velo, también llamada la Nebulosa Escoba de la Bruja (mola ese nombre, jajaja...).

En medio, bajo la escoba, se encuentra el Triángulo de Prickering Wisp.

Y la nebulosa de abajo del todo es la Nebulosa del Velo Oeste.

Estos objetos de cielo profundo son el remanente de una supernova que ocurrió hace entre 12000 y 20000 años y que se encuentra en la constelación del Cisne. Su tamaño aparente en el cielo (si se pudiese ver a simple vista cosa imposible), sería como 6 veces el diámetro de la Luna llena.

Se encuentra a una distancia de unos 1470 años luz de nuestro planeta, pero hay estudios que indican que está más lejos, como 2397 años luz, vamos que si te quieres dar una vuelta por esta supernova va a hacerte falta recargar el depósito de tu cohete espacial un gritón de veces... 😂

EXIF: Usé una Sony A7R full spectrum, con un filtro L-Enhace que bloque la contaminación lumínica, y un telescopio Skywatcher ed80 de 600mm f7,5 con un reductor 0,85, que deja la focal en 510mm efectivos. Vamos la lente era un 510mm a f6,375.

Se trata de dos paneles de unas 60 fotos a 120 segundos cada una a ISO 6400, con sus darks, sus flats, y sus bias.

Use mi montura Explore Scientific EXOS 2, y el guiado lo hice con un tubo Xvbony 120mm f4, y una cámara qhy5 monocromo.

El programa de adquisición fue N.I.N.A. y los paneles los procesé con PI y PS.

Espero que os guste.

Saludos.

Going through some data archives looking for lost data I never processed, here is over five hours of collected data from late 2023 on the Bubble Nebula.

From Wikipedia: “NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575. The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow.”

Um pouco de Mitologia:

Segundo a Wikipédia: Na mitologia Nórdica Fenrir é um lobo monstruoso.Na mitologia Fenrir é pai dos lobos SKOLL e HATI e é um dos filhos de LOKI.É pressagiado a matar o Deus ODIN durante RAGNAROK e ser morto pelo filho de ODIN VIDAR.

Localizado na costelação de Escorpião, a semelhança com o monstro da mitologia aparece pronto para o ataque, como uma imensa sombra escura saltando no espaço.

Sempre que via imagens de grande campo dessa região imaginava ser possivel um close nesta linda região. Já estava em meus planos a pelo menos 2 anos está captura. Com um céu maravilhoso, em 3 noites pude juntar dados suficientes para compor uma bela imagem desse objeto.

O campo é totalmente envolto em uma nebulosa de emissão, com uma densa nuvem de poeira formando Fenrir. As estrelas no campo são de diversos tipos e idades diferentes, como as cores atestam.

O mais engraçado de toda essa história, é que esse apelido não oficial, surgiu na Astronomia amadora. Depois que um astronomo amador da Australia Paul Haese fotografou esse objeto, Rolf Wahl Olsen da Nova Zelândia notou a semelhança com o monstro da mitologia e popularizou o objeto como FENRIR NEBULA.

SL 17 (Sandqvist and Lindroos 17) é a designação oficial desse objeto.

A Little Bit of Mythology:

According to Wikipedia: In Nordic mythology Fenrir is a monstrous wolf. In mythology Fenrir is the father of the wolves SKOLL and HATI and is one of the sons of LOKI. He is presaged to kill the ODIN God during RAGNAROK and be killed by the son of ODIN VIDAR.

Located in the constellation of Scorpio, the resemblance to the monster of mythology appears ready for attack, like an immense dark shadow leaping into space.

Whenever I saw images of the great field of this region I imagined a close-up of this beautiful region to be possible. I was already in my plans for at least 2 years is catch. With a wonderful sky, in 3 nights I was able to gather enough data to compose a beautiful image of this object.

The field is totally encased in an emitting nebula, with a dense cloud of dust forming Fenrir. The stars in the field are of different types and ages, as the colors attest.

The funniest of all this story, is that this unofficial nickname, arose in amateur astronomy. After an Australian amateur astronomer Paul Haese photographed this object, Rolf Wahl Olsen of New Zealand noticed the resemblance to the monster of mythology and popularized the object as FENRIR NEBULA.

SL 17 (Sandqvist and Lindroos 17) is the official name of this object.

NGC 7023 (talvolta nota come Nebulosa Iride o con la sigla C 4) è una nebulosa diffusa visibile nella costellazione boreale di Cefeo. Fu scoperta da William Herschel nel 1794. NGC 7023 è una nebulosa a riflessione, ossia riflette la luce di alcune stelle vicine; probabilmente la stella principale responsabile della sua illuminazione è proprio la stellina di settima grandezza, catalogata come HD 200775, la quale si troverebbe avvolta dalla nebulosa, assieme ad altre stelle meno brillanti nate dalle sue polveri e che vanno a formare l'ammasso aperto. La nebulosa dista da noi probabilmente circa 1400 anni luce e misura circa 6 al. Fa probabilmente parte del vasto Complesso nebuloso molecolare di Cefeo.
