Edited Vista image from the European Southern Observatory of the Orion Nebula. Color/processing variant.
The Great Nebula in Orion is featured in this sweeping image from NASAs Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year. The Orion Nebula (also catalogued as Messier 42) is located in the sword of Orion, hanging from his famous belt of three stars. The star cluster embedded in the nebula is visible to the unaided human eye as a single star, with some fuzziness apparent to the most keen-eyed observers. Because of its prominence, cultures all around the world have given special significance to Orion. The Maya of Mesoamerica envision the lower portion of Orion, his belt and feet (the stars Saiph and Rigel), as being the hearthstones of creation, similar to the triangular three-stone hearth that is at the center of all traditional Maya homes. The Orion Nebula, lying at the center of the triangle, is interpreted by the Maya as the cosmic fire of creation surrounded by smoke.
The metaphor of a cosmic fire of creation is apt. The Orion Nebula is an enormous cloud of dust and gas where vast numbers of new stars are being forged. It is one of the closest sites of star formation to Earth and therefore provides astronomers with the best view of stellar birth in action. Many other telescopes have been used to study the nebula in detail, finding wonders such as planet-forming disks around newly forming stars. WISE was an all-sky survey giving it the ability to see these sites of star formation in a larger context. This view spans more than six times the width of the full Moon, covering a region nearly 100 light-years across. In it, we see the Orion Nebula surrounded by large amounts of interstellar dust, colored green.
Astronomers now realize that the Orion Nebula is part of the larger Orion molecular cloud complex, which also includes the Flame Nebula. This complex in our Milky Way Galaxy is actively making new stars. It is filled with dust warmed by the light of the new stars within, making the dust glow in infrared light.
Color in this image represents specific infrared wavelengths. Blue represents light emitted at 3.4-micron wavelengths and cyan (blue-green) represents 4.6 microns, both of which come mainly from hot stars. Relatively cooler objects, such as the dust of the nebulae, appear green and red. Green represents 12-micron light and red represents 22-micron light.

Edited Spitzer Space Telescope image of stars in the gas clouds of the Orion Nebula. Inverted grayscale variant.
Original caption: This new view of the Orion nebula highlights fledgling stars hidden in the gas and clouds. It shows infrared observations taken by NASA's Spitzer Space Telescope and the European Space Agency's Herschel mission, in which NASA plays an important role.
A star forms as a clump of this gas and dust collapses, creating a warm glob of material fed by an encircling disk. These dusty envelopes glow brightest at longer wavelengths, appearing as red dots in this image. In several hundred thousand years, some of the forming stars will accrete enough material to trigger nuclear fusion at their cores and then blaze into stardom.
The nebula is found below the three belt stars in the famous constellation of Orion the Hunter, which appears at night in northern latitudes during fall and then throughout winter. At a distance of around 1,500 light-years away from Earth, the nebula cannot quite be seen with the naked eye. Binoculars or a small telescope, however, are all it takes to get a good look in visible light at this stellar factory.
Spitzer is designed to see shorter infrared wavelengths than Herschel. By combining their observations, astronomers get a more complete picture of star formation. The colors in this image relate to the different wavelengths of light, and to the temperature of material, mostly dust, in this region of Orion. Data from Spitzer show warmer objects in blue, with progressively cooler dust appearing green and red in the Herschel datasets. The more evolved, hotter embryonic stars thus appear in blue.
The combined data traces the interplay of the bright, young stars with the cold and dusty surrounding clouds. A red garland of cool gas also notably runs through the Trapezium, the intensely bright region that is home to four humungous blue-white stars, and up into the rich star field.
Infrared data at wavelengths of 8.0 and 24 microns from Spitzer are rendered in blue. Herschel data with wavelengths of 70 and 160 microns are represented in green and red, re

NASA's Spitzer and Hubble Space Telescopes have teamed up to expose the chaos that baby stars are creating 1,500 light-years away in a cosmic cloud called the Orion Nebula.
This striking infrared and visible-light composite indicates that four monstrously massive stars at the center of the cloud may be the main culprits in the familiar Orion constellation. The stars are collectively called the "Trapezium." Their community can be identified as the yellow smudge near the center of the image.
Swirls of green in Hubble's ultraviolet and visible-light view reveal hydrogen and sulfur gas that have been heated and ionized by intense ultraviolet radiation from the Trapezium's stars. Meanwhile, Spitzer's infrared view exposes carbon-rich molecules called polycyclic aromatic hydrocarbons in the cloud. These organic molecules have been illuminated by the Trapezium's stars, and are shown in the composite as wisps of red and orange. On Earth, polycyclic aromatic hydrocarbons are found on burnt toast and in automobile exhaust.
Together, the telescopes expose the stars in Orion as a rainbow of dots sprinkled throughout the image. Orange-yellow dots revealed by Spitzer are actually infant stars deeply embedded in a cocoon of dust and gas. Hubble showed less embedded stars as specks of green, and foreground stars as blue spots.
Stellar winds from clusters of newborn stars scattered throughout the cloud etched all of the well-defined ridges and cavities in Orion. The large cavity near the right of the image was most likely carved by winds from the Trapezium's stars.
Located 1,500 light-years away from Earth, the Orion Nebula is the brightest spot in the sword of the Orion, or the "Hunter" constellation. The cosmic cloud is also our closest massive star-formation factory, and astronomers believe it contains more than 1,000 young stars.
The Orion constellation is a familiar sight in the fall and winter night sky in the northern hemisphere. The nebula is invisible to the unaided eye, but can be resolved with binoculars or small telescopes.
This image is a false-color composite where light detected at wavelengths of 0.43, 0.50, and 0.53 microns is blue. Light at wavelengths of 0.6, 0.65, and 0.91 microns is green. Light at 3.6 microns is orange, and 8.0 microns is red.
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.

M42, also known as the Great Nebula in Orion, is one of the brightest nebulas in the sky and one of the few visible to the naked eye. It is located around 1,300 light-years from earth and it is estimated to be 24 light-years across. The Orion Nebula is a star formation region, where clouds of gas start to group into denser areas until eventually collapsing into a ball of plasma to form a star.
At the bottom left of the picture, there is a very faint nebula, called the Horsehead Nebula, which is also part of the same larger molecular complex.

Reprocessed data from last February, M42 shot in Ha and Hb to show the difference between hydrogen emission lines. The channels were linear fitted across the nebulous ADU range (leading to blue stars), then mapped R:Ha, G:Avg(Ha,Hb), B:Hb. The background was neutralized and gradients were removed, stretching was done with a histogram stretch in luminosity only and contrast and saturation was enhanecd to make the differences a bit more visible.

Direkt links vom Orionnebel befindet sich noch der kleinere blaue Running-Man-Nebel. Der Name Running Man entstand, weil der dunkle Mittelteil des Nebels so ähnlich aussieht wie ein laufender Mann. Alle Nebel sind Sternentstehungsgebiete und gehören zu einer größeren Wasserstoff-Molekülwolke im Sternbild Orion.

Original caption: The individual images of the Orion Nebula where obtained with WFI at the ESO/MPG 2.2m telescope on the night of Dec.10-11, 2001. Several images were obtained in the following filters: U (363.690 nm; 15 images for a total exposure time of 1.25 hour); B (456.252 nm; 14 images; total exp.: 21 min); Oxygen [OIII] (502.393 nm; 15 images; total exp.: 32 min); Halpha (658.827 nm; 15 images; total exp.: 32 min); Sulphur [SII] (676.340 nm; 10 images; total exp.: 30 min). ESO Press Photo eso0421 is a false-colour composite of all of the images obtained in B, Halpha, [OIII], and [SII] where each waveband was associated to a given colour: B to blue, [OIII] to green; Halpha to orange, and [SII] to red. The field of view covers 34 x 33 arcmin2. North is up and East is to the left. The images were first processed by Massimo Robberto (STSci) then further combined by Hännes Heyer and Henri Boffin (ESO).
Taken with a telescope and Canon DSLR, 240 second exposure. Truly a marvel of the night sky that can be captured on telescopes large or small.
Messier 42,
From Wikipedia:
The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated south of Orion's Belt. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. Older texts frequently referred 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. There are also supersonic "bullets" of gas piercing the dense hydrogen clouds of the Orion Nebula. Each bullet is ten times the diameter of Pluto's orbit and tipped with iron atoms glowing bright blue. They were probably formed one thousand years ago from an unknown violent event.

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.
Clouds stopped my imaging session and Orion had risen to view, so I took a quick LRGB series (3x1 min per channel). The colored streak near the top is most likely a geosynchronous satellite.
A 25-second exposure using a Vivitar 2x teleconverter and a Vivitar 135MM telephoto lens of the three "stars" in Orion's Sword. The center star is the Orion Nebula, lit by the Trapezium cluster. The "trailing" in the image is because I accidentally bumped the tripod to my Meade ETX-80AT telescope (which I was using for guided astrophotography) while I had the shutter held open.
The mighty Orion and its Great Nebula. 10x30s per channel added to the previous set (3x5min RGB, 2x5min L) and bit of processing shows a bit of promise for this wonderful nebula.
More light is still needed but the nordic skies haven't been too co-operative lately with one clear night in early November and one clear evening in January.

The Great Nebula in Orion is featured in this sweeping image from NASAs Wide-field Infrared Survey Explorer, or WISE. The constellation of Orion is prominent in the evening sky throughout the world from about December through April of each year. The Orion Nebula (also catalogued as Messier 42) is located in the sword of Orion, hanging from his famous belt of three stars. The star cluster embedded in the nebula is visible to the unaided human eye as a single star, with some fuzziness apparent to the most keen-eyed observers. Because of its prominence, cultures all around the world have given special significance to Orion. The Maya of Mesoamerica envision the lower portion of Orion, his belt and feet (the stars Saiph and Rigel), as being the hearthstones of creation, similar to the triangular three-stone hearth that is at the center of all traditional Maya homes. The Orion Nebula, lying at the center of the triangle, is interpreted by the Maya as the cosmic fire of creation surrounded by smoke.
The metaphor of a cosmic fire of creation is apt. The Orion Nebula is an enormous cloud of dust and gas where vast numbers of new stars are being forged. It is one of the closest sites of star formation to Earth and therefore provides astronomers with the best view of stellar birth in action. Many other telescopes have been used to study the nebula in detail, finding wonders such as planet-forming disks around newly forming stars. WISE was an all-sky survey giving it the ability to see these sites of star formation in a larger context. This view spans more than six times the width of the full Moon, covering a region nearly 100 light-years across. In it, we see the Orion Nebula surrounded by large amounts of interstellar dust, colored green.
Astronomers now realize that the Orion Nebula is part of the larger Orion molecular cloud complex, which also includes the Flame Nebula. This complex in our Milky Way Galaxy is actively making new stars. It is filled with dust warmed by the light of the new stars within, making the dust glow in infrared light.
Color in this image represents specific infrared wavelengths. Blue represents light emitted at 3.4-micron wavelengths and cyan (blue-green) represents 4.6 microns, both of which come mainly from hot stars. Relatively cooler objects, such as the dust of the nebulae, appear green and red. Green represents 12-micron light and red represents 22-micron light.

This new view of the Orion nebula highlights fledgling stars hidden in the gas and clouds. It shows infrared observations taken by NASA's Spitzer Space Telescope and the European Space Agency's Herschel mission, in which NASA plays an important role.
A star forms as a clump of this gas and dust collapses, creating a warm glob of material fed by an encircling disk. These dusty envelopes glow brightest at longer wavelengths, appearing as red dots in this image. In several hundred thousand years, some of the forming stars will accrete enough material to trigger nuclear fusion at their cores and then blaze into stardom.
The nebula is found below the three belt stars in the famous constellation of Orion the Hunter, which appears at night in northern latitudes during fall and then throughout winter. At a distance of around 1,500 light-years away from Earth, the nebula cannot quite be seen with the naked eye. Binoculars or a small telescope, however, are all it takes to get a good look in visible light at this stellar factory.
Spitzer is designed to see shorter infrared wavelengths than Herschel. By combining their observations, astronomers get a more complete picture of star formation. The colors in this image relate to the different wavelengths of light, and to the temperature of material, mostly dust, in this region of Orion. Data from Spitzer show warmer objects in blue, with progressively cooler dust appearing green and red in the Herschel datasets. The more evolved, hotter embryonic stars thus appear in blue.
The combined data traces the interplay of the bright, young stars with the cold and dusty surrounding clouds. A red garland of cool gas also notably runs through the Trapezium, the intensely bright region that is home to four humungous blue-white stars, and up into the rich star field.
Infrared data at wavelengths of 8.0 and 24 microns from Spitzer are rendered in blue. Herschel data with wavelengths of 70 and 160 microns are represented in green and red, respectively.
This wide-field view of the Orion Nebula (Messier 42), lying about 1350 light-years from Earth, was taken with the VISTA infrared survey telescope at ESO’s Paranal Observatory in Chile. The new telescope’s huge field of view allows the whole nebula and its surroundings to be imaged in a single picture and its infrared vision also means that it can peer deep into the normally hidden dusty regions and reveal the curious antics of the very active young stars buried there. This image was created from images taken through Z, J and Ks filters in the near-infrared part of the spectrum. The exposure times were ten minutes per filter. The image covers a region of sky about one degree by 1.5 degrees. ASU-IPF-3071

A re-processing of old data (omitting the 60 second exposures, which didn't add much). There's a bit more noise come through but there's a hell of a lot more detail showing and all in all I think I'm pretty pleased with the upgrade at such a low amount of time!
