The Orion Nebula, imaged with a 90mm William optic's refractor telescope. A total of 9 x 3 minute exposures usinf a Ha filter fitted to a modified Canon EOS 600D camera.
“Resembling an interstellar Frisbee, this is a disk of dust seen edge-on around a newborn star in the Orion nebula, located 1,500 light-years away. Because the disk is edge-on, the star is largely hidden inside, in this striking Hubble Space Telescope picture. The disk may be an embryonic planetary system in the making. Our solar system probably formed out of just such a disk 4.5 billion years ago. At 17 times the diameter of our own solar system, this disk is the largest of several recently discovered in the Orion nebula.
The left image is a three-color composite, taken in blue, green, and red emission lines from glowing gas in the nebula. The right image was taken through a different filter, which blocks any bright spectral emission lines from the nebula, and hence the disk itself is less distinctly silhouetted against the background. However, clearly visible in this image are nebulosities above and below the plane of the disk; these betray the presence of the otherwise invisible central star, which cannot be seen directly due to dust in the edge-on disk.
The images were taken between January 1994 and March 1995, and a study of their characteristics has been submitted for publication to the Astronomical Journal.

The M42 Orion Nebula using my new Tamron 70-300mm telephoto lens (cropped image).
This pic is noisier than I'd hoped as I had difficulty getting the motor drive to track at the correct speed so ended up using a high ISO and shorter exposure. That considered, I'm pleased with the way it turned out from an entry level telephoto lens!

Last night's dabbling with the
telescope - Orion's Sword!
I rarely shoot deep sky objects in 'Portrait' layout on my camera, but for this I decided to do things differently - so I could capture the entirety of Orion's 'Sword' in one frame.
At the top of this photo is the Running Man nebula, consisting of NGC 1973, NGC 1975 and NGC 1977.
At the center, and the showcase of Orion's sword is the Great Nebula of Orion, designated as Messier 42, and an H-II region known as Messier 43.
Below the Great Nebula, resides NGC 1980, and the star ι Ori (Hatsya).
This is 25-30 second shots at ISO1600, plus 10 5-second shots for the core, captured via Nikon D5100 and a Meade DS2090 piggybacked to a Meade LX200
After months of clouds and rain, all is right in the world. Happy astronomer is happy! :)
I managed to capture the Orion Nebula (M42) with my 300mm lens using DeepSkyStaker and 24 raw captures. I'm surprised with how much detail managed to be captured. Processed in Photoshop and star diffraction spikes added with Topaz Star Effects.
La Nebulosa di Orione (nota anche come Messier 42 o M 42, NGC 1976) è una nebulosa diffusa molto conosciuta perché tra le più brillanti del cielo notturno, talmente luminosa da essere facilmente individuabile già con un piccolo binocolo.
Per questo sembra anche apparentemente semplice da elaborare, ma l'enorme differenza di luminosità tra le sue deboli strutture e le parti più luminose la rendono invece particolarmente difficile.
Le parti più flebili possono essere evidenziate solo con tempi di esposizione lunghi che però sono tali da saturare le zone che presentano già un elevata luminosità! Quindi se si espone poco non si evidenziano le strutture deboli ed al contrario se si espone adeguatamente si rischia di saturare le parti già luminose della nebulosa come nel caso delle stelle che formano il trapezio.
L’unica soluzione consiste nell'acquisire molte serie di frames realizzate con tempi via via sempre superiori al precedente e poi elaborarle in HDR.

My second attempt at shooting M42 on a rare night of clear sky in Singapore. Taken at Changi Beach - a place located at the eastern end of Singapore main island. Night sky there is definitely darker compared to where I first attempted M42 (which was in the central part of severe light polluted Singapore).
But the imaging session was short lived as the lens fogged up after 40 plus shots. What a waste! Guess I have to bring some heat packs along if I am going to this location next time.
Though the image is noisy, I am quite satisfied with the end results of the stacked image. The running man nebula is visible in the photo as well. Waiting for the next clear night to collect more subs to add on to this group of subs.

Edited European Southern Observatory image of the Orion Nebula.
Original caption: The left-hand panel shows the Orion Nebula in visible light. Most of the light from the spectacular clouds comes from hydrogen gas glowing under the fierce ultraviolet glare from the central hot young stars. The region above the centre is clearly obscured by dust clouds. On the right the VISTA infrared view is shown. By observing infrared light many new features appear, including large numbers of young stars close to the centre and many curious red objects, associated with young stars and their outflows, in the region above the centre.

Little bit of light pollution from the moon, but otherwise, perfect night for shooting.
21st-22nd January 2021, The first imaging session in over 2 months and the first opportunity to try out my new Optolong L-Pro filter to see how effective it is against London light pollution. I think it makes a big improvement. This composite was made by blending two images, one made from 5 minute and 2-minute shots for the outer parts of the nebula and one made from 30-second shots for the bright inner region known as the Trapezium. This is just a test so the image isn't particularly well-framed but it came out reasonably well.
[From Wikipedia]The Orion Nebula (also known as Messier 42 and NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion.[b] It is one of the brightest nebulae, and is visible to the naked eye in the night sky. It is approximately 1,344 light-years away and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2,000 times that of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula.
The Orion Nebula is one of the most scrutinized and photographed objects in the night sky and is among the most intensely studied celestial features. The nebula has revealed much about the process of how stars and planetary systems are formed from collapsing clouds of gas and dust. Astronomers have directly observed protoplanetary disks, brown dwarfs, intense and turbulent motions of the gas, and the photo-ionizing effects of massive nearby stars in the nebula.

I tried pulling some more of the sky glow out and went a little less aggressive with the curves. It might've lost me some detail, but results in a more pleasant image I think. Not much different though at a glance.
M42 - The Great Orion Nebula. This picture of the Orion nebula is actually a mosaic of 5 separate pictures and, therefore, seems to have a little better detail than the previous image of M42 posted here. The photos were merged in Photoshop. Pictures were taken using a Nikon D50 camera and the Powell Observatory 30" F/5 Newtonian Telescope located near Louisburg, KS. Taken 1/22/07 by Doug Spalding. The region at the bottom of the picture is classified as M43 (Messier 43). To view as a larger image click on the image, then the magnifying glass.

Third try at this DSO in the middle of light-polluted Singapore. Clear weather. No lens fogging problems unlike the first two attempts. Only problem was satellite signals keep disconnecting at this location. Only few subs were collected as a result. Despite so, the resultant stacked photo definitely looks better than previous tries. Running Man Nebula is vaguely visible on the right.

This spectacular color panorama of the center of the Orion Nebula is one of the largest pictures ever assembled from individual images taken with NASA's Hubble Space Telescope. The picture, seamlessly composited from a mosaic of 15 separate fields, covers an area of sky about five percent the area covered by the full Moon.
The seemingly infinite tapestry of rich detail revealed by Hubble shows a churning, turbulent star factory set within a maelstrom of flowing, luminescent gas. Though this 2.5 light-year-wide view is still a small portion of the entire nebula, it includes almost all of the light from the bright, glowing clouds of gas and a star cluster associated with the nebula. Hubble reveals details as small as 4.1 billion miles across.
Hubble observing time was devoted to making this panorama because the nebula is a vast laboratory for studying the processes that gave birth to our own Sun and solar system 4.5 billion years ago. Many of the nebula's details can't be captured in a single picture — any more than one snapshot of the Grand Canyon yields clues to its formation and history. Like the Grand Canyon, the Orion Nebula has a dramatic surface topography — of glowing gases instead of rock — with peaks, valleys, and walls. They are illuminated and heated by a torrent of energetic ultraviolet light from its four hottest and most massive stars, called the Trapezium, which lie near the center of the image.
In addition to the Trapezium, this stellar cavern contains hundreds of other young stars at various stages of formation. High-speed jets of hot gas spewed by some of the infant stars send supersonic shock waves tearing into the nebula at 100,000 miles per hour. These shock waves appear as thin, curved loops, sometimes with bright knots on their end (the brightest examples are near the bright star at the lower left).
The mosaic reveals at least 153 glowing protoplanetary disks (first discovered with Hubble in 1992 and dubbed "proplyds") that are believed to be embryonic solar systems that will eventually form planets. (Our solar system has long been considered the relic of just such a disk that formed around the newborn Sun). The abundance of such objects in the Orion Nebula strengthens the argument that planet formation is a common occurrence in the universe. The proplyds that are closest to the Trapezium stars (image center) are shedding some of their gas and dust. The pressure of starlight from the hottest stars forms "tails," which act like wind vanes pointing away from the Trapezium. These tails result from the light from the star pushing the dust and gas away from the outside layers of the proplyds. In addition to the luminescent proplyds, seven disks are silhouetted against the bright background of the nebula. These dark objects allow Hubble astronomers to estimate the masses of the disks as at least 0.1 to 730 times the mass of our Earth.
Located 1,500 light-years away, along our spiral arm of the Milky Way, the Orion Nebula is located in the middle of the sword region of the constellation Orion the Hunter, which dominates the early winter evening sky, at northern latitudes. The stars have formed from collapsing clouds of interstellar gas within the last million years. The most massive clouds have formed the brightest stars near the center and these are so hot that they illuminate the gas left behind after the period of star formation was complete. The more numerous faint stars are still in the process of collapsing under their own gravity, but have become hot enough in their centers to be self luminous bodies.
To create this color mosaic, 45 separate images of the Orion Nebula were taken in blue, green, and red between January 1994 and March 1995. Light emitted by oxygen is shown as blue, hydrogen emission is shown as green, and nitrogen emission as red. The overall color balance is close to that which an observer living near the Orion Nebula would see. The irregular borders produced by the Hubble images have been smoothed out by the addition of images from the European Southern Observatory in Chile, these being about 2% of the area shown here and lying at the top left corner.

(Mi primera astrofotografía con seguimiento)
Ya en 1610 Galileo observó la espada de Orión pero no vio la nebulosa, el mismo año, Nicolas-Claude Fabri de Peiresc la describió como una "pequeña nube iluminada". En 1654 Giovanno Batista Hordierna contaba 22 estrellas en la espada de Orion "esta Luminosa es tan admirable puesto que es una luz que no se puede resolver y en cuyo centro se pueden contar tres estrellas" (primera descripción de lo que hoy se conoce como el trapecio). En 1656 Christiaan Huygens la describe "un objeto portentoso, con toda certeza único entre las estrellas fijas". En 1769 Charles Messier le otorgó su nombre más popular: Messier 42. En 1789 el Astrónomo Real William Herschel la describió "una niebla llameante y sin forma, material caótico que formará futuros soles". En 1865 William Huggins la fotografio, ningún otro objeto de cielo profundo había sido fotografiado antes y en la actualidad sigue siendo el más fotografiado.
Excitados por la radiación ultravioleta intensa de las estrellas cercanas, el oxígeno y el hidrógeno de Messier 42 se ionizan emitiendo la característica luz coloreada. La coloración violeta del lado oriente es la refulgente luz azul de las estrellas masivas que se refleja en las cortinas de polvo. Las mediciones de 2009 sugieren que Messier 42 se encuentra a 1,344 años-luz de la tierra y debe medir más de 12 años-luz de diámetro. Las estrellas del Trapecio calientan el gas a una temperatura dos veces superior a la de la superficie del sol. Los astrónomos calculan que hace no más de 1000 años una o varias estrellas masivas estallaron dando lugar a la dispersión de escombros ricos en hierro.
Más de 200 estrellas constituten un gigantesco cúmulo abierto. La mayoría de ellas sólo puede ser detectada mediente detectores infrarojos.
Algunas estrellas como AE Aurigae, Arietis y Mu Columbae, salieron disparadas de Messier 42 a más de 100 km/s.
Muchas de sus estrellas son variables e inestables, se sospecha que el aspecto y luminosidad de la nebulosa ha sufrido cambios en el transcurso de los últimos siglos. En menos de 100.000 años la nube de gas y polvo se habrá disipado dejando al descubierto un bello cúmulo abierto.
Messier 42 es el objeto principal de una estructura mucho mayor: la Gran Nube Molecular de Orión, que incluye otros objetos como Messier 43, la nebulosa Cabeza de Caballo, la nebulosa de la Fogata, Messier 78, el lazo de Barnard etc.
(He recopilado esta información de páginas web, algunos datos podrían no ser exactos)
Images made with the Wide Field/Planetary Camera on NASA's Hubble Space Telescope have revealed the structure of a thin sheet of gas located at the edge of the famous "Great Nebula" in Orion, an estimated 1,500 light-years from Earth.
Astronomers, who compare the appearance of this sheet of gas with that of a rippled window curtain, report that this emission traces the boundary between the hot, diffuse interior of the nebula and an adjacent dense, cool cloud. The sheet is seen in light emitted by atoms of gaseous sulfur (shown in red in the photograph). This emission is strongest under conditions that are intermediate between those in the interior of nebula and those in the dense cloud. The sulfur emission is seen to break into filamentary and clumpy structures with sizes down to the limit of what the telescope can show. In contrast, emission from gaseous oxygen and hydrogen (shown as blue and green, respectively) is favored in the interior of the nebula itself, and is distributed much more smoothly in the image.
The Orion Nebula is a "stellar nursery" — a region where new stars are forming out of interstellar gas. The emission from the nebula is powered by the intense ultraviolet light from a cluster of particularly hot and luminous stars. The sulfur emission seen in the photograph is coming from the region where the light from these stars is "boiling off" material from the face of the dense cloud. This is the very cloud from which the hot stars formed, and is known to harbor additional ongoing star formation.
Astronomers say that this is a good example of a case where, despite the spherical aberration that hobbled many of the early scientific programs that the Hubble Space Telescope was expected to carry out, the telescope was still able to be used to obtain scientifically interesting data with clarity far exceeding that normally possible from the ground.

The Orion Nebula is a diffuse nebula located in the constellation of Orion, the hunter. This nebula is one of the brightest and is naked-eye visible in the night sky. It is seen as the middle "star" of the three in the sword of Orion, just south of Orion's belt. While the "star" appears fuzzy to even sharp-eyed observers, the nebulosity becomes obvious when viewed through binoculars or a small telescope. It lies at a distance of around 1,344 (+/-20) light years away and is the closest region of massive star formation to planet Earth. It has a mass of about 2,000 times the mass of the Sun and is estimated to be 24 light-years across. This nebula is one of the most intensely studied, most scrutinized, and most photographed objects in the night sky.

Probing deep within a neighborhood stellar nursery, the Hubble Space Telescope uncovered a swarm of newborn brown dwarfs. The orbiting observatory's near-infrared camera pierced clouds of gas and dust to reveal about 50 of these objects throughout the Orion Nebula's Trapezium cluster about 1,500 light-years from Earth.

The Orion Nebula, also known as Messier 42 and NGC 1976. One of my all-time favourite celestial objects and something I look forward to imaging every winter. Each attempt brings out more detail and this image shows some of the fainter gas and dust in the vicinity. At the top of the image is the Running Man Nebula (Sh2-279), a reflection nebula north of M42 and an object that in previous attempts I've struggled to resolve. Both objects are part of the asterism known as Orion's Sword which on a clear night can be seen with the naked eye just below the three stars which make up Orion's Belt. M42 is one of the brightest nebulae and is located at a distance of 1,344 ± 20 light-years. It is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light-years across.
For this image, a total of 78 shots were taken at three different exposure times. The three stacked exposures were then blended together in Photoshop to see the fainter details without the very bright heart of the nebula (a very young open cluster known as the Trapezium containing at least four energetic young stars) being massively overexposed. Conditions were surprisingly good for a change with clear sky and no Moon. This image is also my first attempt at processing on a Mac machine with a large monitor instead of struggling to see things properly on my PC laptop. I think it made a difference.

De Sky Safari: La nebulosa de Orión es tal vez el objeto de espacio profundo más fotografiado del cielo. Es la única nebulosa visible a simple vista, al sur del cinturón de Orión.
Fue descubierta en 1656 por Christian Huygens y fue posteriormente incluida por Charles Messier en su catálogo como Messier 42 o M42. Su tamaño aparente es de más de cuatro lunas llenas.
Es una nebulosa de emisión, cuya luz roja se debe al hidrógeno ionizado. Se encuentra a 1350 años luz de la tierra y tiene 24 años luz de diámetro. Es parte del Complejo Molecular de Orión, una nube que incluya el Bucle de Barnard, las nebulosas Cabeza de Caballo, Llama y M78.
Es la región de formación de estrellas masivas más cercana a la tierra.

La nebulosa de Orión, también conocida como Messier 42, M42, o NGC 1976, es una nebulosa difusa situada al sur del Cinturón de Orión. Es una de las nebulosas más brillantes que existen, y puede ser observada a simple vista sobre el cielo nocturno. Está situada a 1.270±76 años luz de la Tierra, y posee un diámetro aproximado de 24 años luz. Algunos documentos se refieren a ella como la Gran Nebulosa de Orión, y los textos más antiguos la denominan Ensis, palabra latina que significa "espada", nombre que también recibe la estrella Eta Orionis, que desde la Tierra se observa muy próxima a la nebulosa.
La nebulosa de Orión es uno de los objetos astronómicos más fotografiados, examinados, e investigados. De ella se ha obtenido información determinante acerca de la formación de estrellas y planetas a partir de nubes de polvo y gas en colisión. Los astrónomos han observado en sus entrañas discos protoplanetarios, enanas marrones, fuertes turbulencias en el movimiento de partículas de gas y efectos fotoionizantes cerca de estrellas muy masivas próximas a la nebulosa.

The Messier Catalog, sometimes known as the Messier Album or list of Messier objects, is one of the most useful tools in the astronomy hobby. In the middle of the 18th century, the return of Halley's comet helped to prove the Newtonian theory, and helped to spark a new interest in astronomy. During this time, a French astronomer named Charles Messier began a life-long search for comets. He would eventually discover 15 of them. On August 28, 1758, while searching for comets, Messier found a small cloudy object in the constellation Taurus. He began keeping a journal of these nebulous (cloudy) objects so that they would not be confused with comets. This journal is known today as the Messier Catalog, or Messier Album. The deep sky objects in this catalog are commonly referred to as Messier objects.
This dramatic image offers a peek inside a cavern of roiling dust and gas where thousands of stars are forming. The image, taken by the Advanced Camera for Surveys (ACS) aboard NASA/ESA Hubble Space Telescope, represents the sharpest view ever taken of this region, called the Orion Nebula. More than 3,000 stars of various sizes appear in this image. Some of them have never been seen in visible light. These stars reside in a dramatic dust-and-gas landscape of plateaus, mountains, and valleys that are reminiscent of the Grand Canyon. The Orion Nebula is a picture book of star formation, from the massive, young stars that are shaping the nebula to the pillars of dense gas that may be the homes of budding stars. The bright central region is the home of the four heftiest stars in the nebula. The stars are called the Trapezium because they are arranged in a trapezoid pattern. Ultraviolet light unleashed by these stars is carving a cavity in the nebula and disrupting the growth of hundreds of smaller stars. Located near the Trapezium stars are stars still young enough to have disks of material encircling them. These disks are called protoplanetary disks or "proplyds" and are too small to see clearly in this image. The disks are the building blocks of solar systems. The bright glow at upper left is from M43, a small region being shaped by a massive, young star's ultraviolet light. Astronomers call the region a miniature Orion Nebula because only one star is sculpting the landscape. The Orion Nebula has four such stars. Next to M43 are dense, dark pillars of dust and gas that point toward the Trapezium. These pillars are resisting erosion from the Trapezium's intense ultraviolet light. The glowing region on the right reveals arcs and bubbles formed when stellar winds - streams of charged particles ejected from the Trapezium stars - collide with material. The faint red stars near the bottom are the myriad brown dwarfs that Hubble spied for the first time in the nebula in visible light. Sometimes called "failed stars," brown dwarfs are cool objects that are too small to be ordinary stars because they cannot sustain nuclear fusion in their cores the way our Sun does. The dark red column, below, left, shows an illuminated edge of the cavity wall. The Orion Nebula is 1,500 light-years away, the nearest star-forming region to Earth. Astronomers used 520 Hubble images, taken in five colours, to make this picture. They also added ground-based photos to fill out the nebula. The ACS mosaic covers approximately the apparent angular size of the full moon. The Orion observations were taken between 2004 and 2005.
Located approximately 1300 Light years from earth lies the Great Orion Nebula in the constellation of Orion, sometimes referred to as "Orions Sword". The Nebula is part of the "Orion Molecular Cloud Complex"
The Orion Nebula itself is about 24 light years across and can be seen with the naked eye quite easily, through a telescope with the naked eye it appears as a greenish cloud of dust

These images show the edge of the vast molecular cloud that lies behind the Orion Nebula, 1400 light-years from Earth. The image of the left shows a wide-field view of the region, as seen with the HAWK-I instrument, installed at the Very Large Telescope. A small region is highlighted with a white rectangle, and the rightmost image shows that region in stunning fiery detail, observed with the Atacama Large Millimeter/submillimeter Array (ALMA).
