Nome: NGC 6888, Caldwell 27, Sharpless 105

Tipo: Nebulosa de emissão

Distância: 5.000 anos-luz

Constelação: Cisne [1]

Estrelas massivas têm vidas curtas e espetaculares. Esta imagem revela detalhes dramáticos da Nebulosa Crescente, uma gigantesca concha gasosa criada por fortes ventos que sopram da estrela central catalogada como HD 192163 (também conhecida como WR 136). [2]

Depois de apenas 4,5 milhões de anos (um milésimo da vida do nosso Sol), a estrela HD 192163 iniciou uma corrida precipitada em direção à formação de uma catastrófica supernova. Primeiro a estrela expandiu-se enormemente para se tornar uma gigante vermelha e ejetou suas camadas externas a uma velocidade de aproximadamente 32000 km/h. Duzentos mil anos depois, tempo que equivale a um piscar de olhos na vida de uma estrela normal, a intensa radiação da camada externa exposta e quente da estrela começou a empurrar o gás para longe a velocidades superiores a 4.8 milhões de km/h! [2]

Quando este "vento estelar" de alta velocidade atingiu o vento gigante vermelho mais lento, formou-se uma densa concha. Na imagem, esta concha apresenta-se na cor vermelha. A força da colisão criou duas ondas de choque: uma que se moveu para fora da casca densa para criar a estrutura filamentar azul, e uma que se moveu para dentro para produzir uma bolha de gás emissor de raio X de milhões de graus Celsius (não é vista nos comprimentos de ondas registrados). A emissão de raios X mais brilhante está próxima da parte mais densa do reservatório de gás comprimido, indicando que o gás quente está evaporando a matéria da casca. A estrela massiva HD 192183 que produziu a nebulosa aparece como o ponto brilhante no centro da imagem. [2]

A estrela HD 192163 provavelmente explodirá como uma supernova em cerca de cem mil anos. Imagens assim permitem aos astrônomos determinar a massa, energia e composição da camada gasosa ao redor desta estrela pré-supernova. Uma compreensão de tais ambientes fornece dados importantes para interpretar observações de supernovas e seus remanescentes. [2]

Name: NGC 6888, Caldwell 27, Sharpless 105

Type: Emission Nebula

Distance: 5,000 light-years

Constellation: Cygnus [1]

Massive stars lead short, spectacular lives. This image reveals dramatic details of the Crescent Nebula, a giant gaseous shell created by powerful winds blowing from the massive star HD 192163 (a.k.a. WR 136, the star is in the center of image). [2]

After only 4.5 million years (one-thousandth the age of the Sun), HD 192163 began its headlong rush toward a supernova catastrophe. First it expanded enormously to become a red giant and ejected its outer layers at about 20,000 miles per hour. Two hundred thousand years later - a blink of the eye in the life of a normal star - the intense radiation from the exposed hot, inner layer of the star began pushing gas away at speeds in excess of 3 million miles per hour! [2]

When this high speed "stellar wind" rammed into the slower red giant wind, a dense shell was formed. In the image, a portion of the shell is shown in red. The force of the collision created two shock waves: one that moved outward from the dense shell to create the blue filamentary structure, and one that moved inward to produce a bubble of million degree Celsius X-ray emitting gas (not viewed on the spectrum eletromagnetic registered). The brightest X-ray emission is near the densest part of the compressed shell of gas, indicating that the hot gas is evaporating matter from the shell. The massive star HD 192183 that has produced the nebula appears as the bright dot at the center of the image. [2]

HD 192163 will likely explode as a supernova in about a hundred thousand years. This image enables astronomers to determine the mass, energy, and composition of the gaseous shell around this pre-supernova star. An understanding of such environments provides important data for interpreting observations of supernovas and their remnants. [2]

The Flaming Star Nebula is an emission and reflection nebula found with the constellation Auriga. There are several other nebulae nearby including IC 410, "The Tadpoles" and the smaller spider nebula. I captured this image on 11/18/20 from my back yard in rural Pennsylvania, USA. Equipment used: Nikon D750, Nikkor 300mm f/2.8 lens, Optolong L-Pro clip-in filter, and an AstroTrac. 23 x 3 minute exposures.

NGC 1579 è una nebulosa diffusa visibile nella costellazione di Perseo. Si individua circa a metà strada fra le stelle ε Persei e ι Aurigae, in un'area che appare fortemente oscurata da nebulose oscure e pertanto priva di ricchi campi stellari. Si tratta di una nebulosa a riflessione, ossia che riflette la luce di stelle vicine, in questo caso una giovane stella T Tauri di magnitudine 8,8. La sua distanza è di circa 2600 anni luce.

Messier 94, also known as Cat's Eye Galaxy and Croc's Eye Galaxy, is a spiral galaxy in constellation Canes Venatici, located at 16 million light years from Earth. It has two ring, an inner one with very active star formation (as it can be seen by the blue ring near the center) and an outer ring, fainter but also with some structure, which need extra integration time to reveal.

This galaxy has a quite large dynamic range between the inner and outer ring making it a bit more complex to process but I believe I managed to balance the ability to see the structures in both ring. Surely a bit flatter than I would like but one must compromise.

This is my second attempt on this galaxy. However, this time it was shot from a Bortle 3 location instead of my home's Bortle 7-8 and difference is striking. Really happy on how this last one came up.

Hope you enjoy.

Astrophotographie avec mon ami Jordane Marliere qui s'est occupé du traitement. Pour ma part j'ai réaliser l'ensemble des prises de vue.

Mettons les voiles et naviguons vers la lumière !NGC 225, également connu sous le nom de l'amas du Voilier (de l'anglais The Sailboat Cluster), est un amas ouvert situé à environ 2 140 années-lumière de la Terre dans la constellation de Cassiopée. L'une de ses étoiles, l'étoile variable “V594 Cas”, illumine la nébuleuse à réflexion bleue vdB 4.Une nébuleuse par réflexion est créée lorsque la lumière d'une étoile est dispersée ou réfléchie par un nuage de poussière voisin. La lumière diffusée à un spectre similaire à celui de l'étoile éclairante, mais en plus bleu, la lumière bleue étant diffusée plus efficacement que les longueurs d'onde rouges plus longues. Cette couleur souvent bleue est donc caractéristique de ces nébuleuses.Cet amas est intégré dans des nuages sombres moléculaires qui reflètent partiellement la lumière des étoiles.

The Soul Nebula is an emission nebula located in Cassiopeia, 6,500 lightyears away. It is a cloud of cosmic gas and dust 150 lightyears wide that's being illuminated and carved by powerful streams of charged particles emanating from an open cluster of stars.

This image of the Soul Nebula completes my project to image the three main nebulae in the same region. The Heart Nebula (IC1805) flic.kr/p/2qgwVE8, The Fish Head Nebula (NGC896) flic.kr/p/2qg6dbf and the Soul Nebula.

This is my last shot from yesterday afternoon, and I went for a close-up of the area along the terminator, in the middle area of the Moon.

The line of three craters prominent in image center includes, from top to bottom, Ptolemaeus, Alphonsus and Arzachel. These are three of my favorite photo targets on the Moon - I always see them as an upside-down snowman.

At bottom center is the large, heavily worn crater Deslandres. It is a very old lunar feature so badly battered it was not recognized as a crater until well into the 20th Century. Instead, it was known as the "Hell Plain", after the crater Hell, prominent in this photo toward the western (left) rim of Deslandres Crater, near the terminator; Hell's interior is still deeply shadowed.

In the upper right is an interesting area, marked by notable rimae features. Rimae are cracks or fissures on the Moon's surface. They sometimes mark areas where the surface has split or cracked due to tectonic forces; other times they mark channels left by flows of lava. In this area you have examples of both kinds. Just in the upper right is one of the most interesting, Rima Hyginus. It is seen as a curved feature with a crater (Hyginus) at the center of the curve. Hyginus is a volcanic caldera, not an impact crater, and the rimae extending from it probably mark lava flow channels. Below Hyginus Crater and Rima Hyginus is a well-defined crater, Treisnecker. To the right of Triesnecker is another area of rimae (Rimae Triesnecker) which are probably the result of tectonic forces below the surface.

Localizada na constelação do Escultor, a galáxia IC5332 ou PGC 71775, é uma linda galáxia espiral simétrica extremamente tênue distante 39 milhões de anos-luz[1]. É uma galáxia espiral do tipo SA(s)d [3] que possui uma baixa taxa de formação estelar sendo assim considerada como uma galáxia estável sem explosão estelar (non-starbust)[2]. Possui uma magnitude aparente de 10.72 com um brilho superficial bastante baixo na ordem de 23.8 magnitude/arcosegundos^1/2 o que exige um céu escuro e muito tempo de exposição na astrofotografia para que seja registrada[1].

Located in the constellation of the Sculptor, galaxy IC5332 or PGC 71775, it is a beautiful, extremely faint symmetrical spiral galaxy away 39 million light-years[1]. It is a spiral galaxy of the SA(s)d [3] type that has a low rate of star formation and is therefore considered a stable galaxy non-starbust[2]. It has an apparent magnitude of 10.72 with a very low surface brightness on the order of 23.8 magnitude/square arc sec which requires a dark sky and a lot of exposure in astrophotography[1].

M42 is a classic of HDR processing. The acronym HDR stands for High Dynamic Range and, with this acronym, we mean a technique that allows us to increase the dynamic range of our sensor, or rather of our image. The dynamic range of a digital sensor is a feature of primary importance for all those photographic genres that include in the photo areas with high brightness variability. Astrophotography is one of the photographic sectors in which we most often, if not always, find ourselves in this condition. In fact, we pass, in the same image, from the intense light of a star to the darkness of the deep sky.

It may happen that in long poses you go to saturate the brightest areas of the image, going to "burn" them, making these areas completely white, losing color and information.

This will happen more frequently the lower the dynamic range of our sensor. But there will still be situations in which it will be impossible to recover certain areas even with very high quality sensors.

It is to overcome this limit that the HDR technique is used. I said that m42 is a classic of this technique, although in my opinion some exaggerate presenting the very dark nucleus almost "venous". I like to keep it bright is still a stellar forge!

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 is a barred spiral galaxy approximately 2.5 million light-years Earth and the nearest major galaxy to the Milky Way.[ The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the Ethiopian (or Phoenician) princess who was the wife of Perseus in Greek mythology.

The virial mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion stars. The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy is more massive than the Milky Way by a margin of some 25% to 50%. This has been called into question by a 2018 study that cited a lower estimate on the mass of the Andromeda Galaxy, combined with preliminary reports on a 2019 study estimating a higher mass of the Milky Way. The Andromeda Galaxy has a diameter of about 220,000 light years, making it the largest member of the Local Group in terms of extension.

The number of stars contained in the Andromeda Galaxy is estimated at one trillion (1×1012), or roughly twice the number estimated for the Milky Way.

The Milky Way and Andromeda galaxies are expected to collide in around 4-5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy. With an apparent magnitude of 3.4, the Andromeda Galaxy is among the brightest of the Messier objects, making it visible to the naked eye from Earth on moonless nights, even when viewed from areas with moderate light pollution.

This was just a test with the L Pro and quite happy with it- can shoot in colour from my backyard which I haven't been able to do for over a decade thanks to increasing light pollution

issues with spacing -getting the distance from focal reducer to camera exactly right remain- need to address

The Raspberry nebula is in the center.( SH2-263 is the red emission nebula and VDB38 is the blue reflection nebula.) The central star is HD34989. To the right is SH2-265 and lower left shows a section of the Lambda Orionis ring SH2-264. The blue light from the star Bellatrix "shines" from the lower right.

This is enough data so i could use only basic processing in PI: DBE, HistogramTransformation, a little SCNR to remove green and a little curves adjustment. So no BackgroundNeutralisation, no ColorCorrection, no Noise reduction etc.

It had been a long time since I wanted to challenge myself with a mosaic, and with the arrival of the summer sky, it was easy to point towards the constellation of Cygnus. So, I aimed my lens towards the North America and Pelican Nebulae. Initially, I wanted to exclude Deneb from my composition as my narrowband filters from Optolong don't handle such bright stars very well. However, considering the various combinations of frames, I liked the presence of the Cygnus's beacon, so I decided to include it, trying to manage it as best as I could. I hope you like the result.

Messier 35 is a large open star cluster 2,800 light-years away that can be seen near Castor's right foot in the constellation Gemini.

M35 - or NGC 2168 as it’s also known - probably contains about 500 stars, and is thought to be about 100 million years old. This might seem very old, but it is relatively young in astronomical terms.

Open star clusters are indeed young objects, generally speaking, especially when compared to globular clusters, which can be as ancient as 12 billion years old.

Messier 35 shines at mag. 5.2, which means it can be seen with the naked eye under dark conditions, but viewing through binoculars or even a small telescope will begin to reveal its sparkling beauty.

The cluster is part of the famous Messier Catalogue conceived by Charles Messier in the 18th century, but it is the only Messier object in the Gemini constellation.

NGC 2158 is also located in Gemini and looks as thought it's right beside M35, but in actual fact it is much further away, at 14,700 lightyears distant.

NGC 2158 is also much older, at 2 billion years old.
