A panoramic mosaic of bright starclouds and dark stardust in the rich region of the Milky Way around the centre of the Galaxy in Sagittarius.
This panorama extends from the tail of Scorpius at far right to Serpens at far left, with the bright Sagittarius Starcloud near the direction of the galactic centre at centre. The Milky Way here is populated by a rich collection of nebulas and star clusters, including - from right to left - the very red Catâs Paw and NGC 6337 in the tail of Scorpius at right, the pink Lagoon and Trifid Nebulas in Sagittarius (left of centre), and the Swan and Eagle Nebulas in Serpens at far left. The Small Sagittarius Starcloud, M24, is at left, flanked above and below by the star clusters M23 and M25. The star clusters M6 and M7 are at right of centre in Scorpius, with M7 lost in the starclouds.
The bright âcloudsâ are masses of stars. The dark regions are obscuring regions of interstellar dust hiding the more distant stars. The actual centre of the Galaxy near the centre of the frame is not visible here in this or any visible light image as it is hidden by dust.
The nebulas at right in Scorpius are much redder as they are obscured by dark interstellar dust which absorbs the shorter blue wavelengths which add to the pink colours of the other nebulas which glow in red and blue wavelengths of hydrogen alpha and beta as well as cyan oxygen III wavelengths.
The mosaic runs along the galactic equator. I present this as a horizontal landscape image with north to the left and south to the right. This is the way you generally see this area in the southern hemisphere. But in the northern hemisphere this region of sky is seen running vertically from south to north, so the mosaic should be turned 90° CW to match that view. However, I shot this from Australia, on April 13, 2016 on a near perfect night for astronomy.
This is a mosaic of 6 segments, each segment being a stack of 4 x 3-minute exposures at f/2.8 with the 135mm Canon L-Series telephoto lens, tracked on the AP 400 mount, and with the filter-modified Canon 5D MkII at ISO 1600. Stacking and stitching in Photoshop CC 2015.

My First astrophoto with my new vintage lens
The Lagoon Nebula (M8, Messier 8 and NGC 6523) is a gigantic interstellar cloud in the Sagittarius constellation. It is classified as an emission nebula), whose ionized gases, mainly hydrogen, emit radiation mainly in the wavelength range of visible red light.
Lagoon Nebula was discovered by Giovanni Hodierna before 1654. Viewed through binoculars, the nebula appears as a distinct oval blob with a defined core. Superimposed on the nebula is a small open cluster of stars. It has an apparent magnitude of 6.0 and is located 4,850 light-years from Earth.

The Lagoon Nebula is a giant interstellar cloud in the constellation of Sagittarius. The nebula is composed of hydrogen gas. The gas glows due to excitation from the radiation of stars within and nearby.
M8 lies 5,000 light years distant within our Milky Way.
This image was captured under high desert skies near Santa Fe, New Mexico, USA with a telescope of 12" aperture at f/8 and an electrically-cooled CCD camera.

First light for my new Boren Simon 8" f/2.8 PowerNewt astrograph!
Acquired for use on wide field deep-sky objects.
It has taken quite a while to sort out the setup for this new telescope, but I think it is getting there. Still some issues with coma in the corners that I am trying to work out. Still, I am encouraged by the results so far.
This is only my 2nd attempt at a narrowband image, and is really only a "rough draft" as it includes only minimal post processing.

These two nebulae are between 4,000 and 5,000 light years from earth and appear in the constellation Sagittarius just above and to the left of the brightest portion of the Milky Way ("above" and "left" when looking south from the northern hemisphere). The open star cluster M21 also appears in this photo, near to the far left, center edge of the frame.
Photographed on the evening of July 7, 2013 from a moderately dark-sky location using a 5 inch aperture, f/4.2 telescope and a Sony NEX-5N digital camera (ISO 3200, a stack of seventy-nine images each exposed for 30 seconds, producing a total exposure integration time of just under 40 minutes). Tracking for each of the 30 second exposures was performed by a Celestron CGEM mount (no manual or auto guiding, standard sidereal rate after All-Star polar alignment).
I've also posted an image that was created with this same setup, but using only one thirty-second exposure (i.e. no stacking, as was done with the above image). The thirty-second image is located HERE.

Astrometry :
My 80ED has a field of view just wide enough to take in both M8 and M20--but I might try this with my 70-300 lens sometime to give them a bit more border (that is, if I can rig up a way to use that lens on my mount somehow)

For 28 years, NASA’s Hubble Space Telescope has been delivering breathtaking views of the universe. Although the telescope has made more than 1.5 million observations of over 40,000 space objects, it is still uncovering stunning celestial gems.
The latest offering is this image of the Lagoon Nebula to celebrate the telescope’s anniversary. Hubble shows this vast stellar nursery in stunning unprecedented detail.
At the center of the photo, a monster young star 200,000 times brighter than our Sun is blasting powerful ultraviolet radiation and hurricane-like stellar winds, carving out a fantasy landscape of ridges, cavities, and mountains of gas and dust. This region epitomizes a typical, raucous stellar nursery full of birth and destruction.

The Messier 8 (aka Lac III-13, NGC 6523, BCA 237 or Sh 2-25), is definitely the protagonist of this rich nebular and stellar field in the Sagittarius constellation, near the centre of our galaxy.
With approximate apparent dimensions of 45’x30’ and a distance of about 4-5 thousand light-years, this very bright emission nebula has a real extension of nearly 100 light-years, factors that make it visible to the naked eye even in suburban areas, and a good target for binoculars or small telescopes, although it takes a somewhat big telescope (10-inch would be very fine) in a dark sky site to fully reveal its splendour to a visual observer – as I had the unforgettable opportunity to witness via a 11-inch SCT from a Bortle 2 sky site.
But the Lagoon Nebula, as it is popularly known, is surrounded by several other nebulae and HII regions, such as Sh 2-29, Sh 2-31, and Sh 2-32, to the bottom left, and M8 itself also encompasses a bright open star cluster, NGC 6530 as well as the famous Hourglass Nebula, at its luminous core, and some dark nebulae showing themselves as beautiful dark filaments cutting through their way along the field, partially blocking our view of the shimmering nebula behind.
This colour combination is the renowned Hubble Palette or SHO (Sulphur-Hydrogen-Oxygen), by which the narrowband SII captured data is assigned to the Red channel, the H-alpha data to Green, and the OIII to Blue. I also used the H-alpha as Luminance channel for this image.
Curiously, this SHO palette, at least in my opinion, makes the “Lagoon Nebula” an even more appropriate name for this object, perhaps because of the blue huge central region surrounded by the golden/brown border.
Please enjoy the view!
Cloudy weather in several moonless nights and processing turned this a work of multiple months.
This image was accomplished with the collaboration of my dear friend Romualdo Caldas.
And, being my inaugural image in narrowband and the first one processed in part with PixInsight, I would like to thank some other people who helped me in those regards: Rafael Compassi, Maicon Germiniani, Ernande Júnior, Gabriel Santos and Luiz Duczmal.

A Nebulosa da Lagoa em Hubble Palette (SHO) e adjacências
A Messier 8 (M8, também conhecida como Lac III-13, NGC 6523, BCA 237 ou Sh 2-25) é definitivamente a nebulosa a protagonizar esse rico campo estelar na constelação do Sagitário, próxima ao centro da nossa galáxia. Com as dimensões aparentes aproximadas de 45’x30’ e uma distância de 4 a 5 milhares de anos-luz da Terra, essa brilhante nebulosa de emissão tem uma extensão real de quase 100 anos-luz, fatores que a tornam visível a olho nu desde até mesmo áreas suburbanas de grandes cidades, e um bom alvo de observação para binóculos e pequenos telescópios, embora seja desejável um telescópio um tanto maior (10 polegadas seria bem razoável) e num céu escuro, para revelar totalmente seu esplendor a um observador visual – como eu mesmo tive a inesquecível oportunidade de testemunhar via um telescópio SCT de 11 polegadas em um local de céu Bortle 2.
Mas a Nebulosa da Lagoa, como é popularmente conhecida, é cercada de várias outras nebulosas e regiões HII, como as Sh 2-29, Sh 2-31 e Sh 2-32, vistas em grupo no região inferior esquerda da imagem. E a própria M8 também hospeda um brilhante aglomerado aberto de estrelas, o NGC 6530, bem como a Nebulosa da Ampulheta, que lhe serve de radiante núcleo, além de algumas nebulosas escuras que se apresentam como belos filamentos negros cortando seu caminho ao longo do campo de visão, parcialmente bloqueando nossa visão da fulgurante nebulosa logo atrás.
Essa combinação de cores é a conhecida Hubble Palette (ou Aquarela do Hubble – ficando assim famosa por ser empregada pelos processadores de imagens do famoso telescópio espacial), ou SHO (Enxofre-Hidrogênio-Oxigênio, na sigla em latim e inglês). Nessa combinação, os dados capturados em banda estreita de SII são atribuídos ao canal Vermelho do conjunto RGB (Vermelho-Verde-Azul), enquanto as capturas na faixa do Hidrogênio-alfa vão para o canal Verde, e as em Oxigênio-III vão para o Azul. Para essa imagem, eu também usei o H-alfa como canal de Luminância.
Curiosamente, esta aquarela SHO – ao menos na minha opinião – torna o nome “Nebulosa da Lagoa” ainda mais apropriado para este objeto, talvez pelo fato de tornar a imensa região central azul, e cercada pelas margens em tons marrons/dourados.
Por favor, desfrute da imagem em alta resolução.
Tempo nublado em muitas noites e o longo período de processamento fizeram deste um trabalho de múltiplos meses.

The centre of the galaxy area of the Milky Way toward Sagittarius and Scorpius, with the Sagittarius Starcloud right of centre, and the Lagoon Nebula (M8) left of centre. The Cat's Paw Nebula (NGC 6334) in Scorpius is at upper right, the Swan Nebula (M17) and Eagle Nebula (M16) are at lower left. To the right of them is the Small Sagittarius Starcloud (M24). At the very top is the Snake Nebula (B72). The main mass of dark nebula is the Pipe Nebula (B78). Above M24 at left is the open cluster M23 while below the M24 star cloud is the cluster M25. The globular M22 is at the bottom edge. At right of frame are the open clusters M6 (in the dark area of the Milky Way) and M7 (in the bright starcloud).
I took this at about 3 am local time, Monday, March 31 from the Warrumbungles Motel grounds near Coonabarabran, NSW, Australia at the OzSky Star Safari 2014. This is a stack of 4 x 4 minute exposures at f/2.8 with the Sigma 50mm lens on the Canon 60Da at ISO 800. The camera was tracking the sky using the iOptron SkyTracker.
I've oriented it horizontally as that's the way the camera was oriented to frame the area as it was rising in the east in the sky. However, from northern latitudes, this area would be framed vertically with the right side of the image in Scorpius (the area farthest south in the Milky Way) at bottom.
Now in summer astrophotography season, our galaxy The Milky Way is showing all of it's wondrous sights. Photographed from my backyard in the Alexander Valley, Sonoma County, Calif.
Messier 8 (M8), also known as the Lagoon Nebula, is a large, bright emission nebula located in the constellation Sagittarius. The star-forming nebula has an apparent magnitude of 6.0 and lies at a distance of 4,100 light years from Earth.

The Lagoon Nebula aka M8 is the largest and brightest of a number of nebulosities in and around Sagittarius.
The Lagoon Nebula, also known as M8 or Messier 8, is a large gas cloud within the Milky Way Galaxy, barely visible to the human eye under good conditions. It appears a few degrees above and to the right of the Teapot asterism in the constellation Sagittarius. Visually about three times the size of the full moon, the Lagoon Nebula is the largest and brightest of a number of nebulosities in and around Sagittarius.
M8 is about 5000 light years away, and roughly 130 light years across in the longer dimension. Composed primarily of hydrogen, much of it ionized (heated or energized) by radiation from the nearby superstar Herschel 36, M8 is known as an emission nebula. As such it also is a star-forming region, sometimes called a “stellar nursery.” There is an open star cluster, NGC 6530, of young, hot, blue stars probably only a few million years old. In addition to these young stars, there are also many dark “Bok” globules of condensing gas and dust on their way to becoming “protostars” and ultimately full-fledged stars like those already formed nearby.

The Trifid is a famous summertime binocular object. Its name means “divided into three lobes.” If you view this nebula through a telescope, you’ll see why.
The Trifid Nebula (Messier 20) is one of the many binocular treasures in the summer Milky Way. Its name means divided into three lobes, although you’ll likely need a telescope to see why. On a dark, moonless night, you can star-hop upward from the spout of the Teapot in Sagittarius to another famous nebula, the Lagoon, also known as Messier 8. In the same binocular field, look for the smaller and fainter Trifid Nebula as a fuzzy patch above the Lagoon. Follow the links below to learn more.
Whether the close-knit nebulosity of the Trifid and Lagoon Nebulae represents a chance alignment or an actual kinship between the two nebulae is open to question. Both the Trifid and Lagoon Nebulae are thought to reside about 5,000 light-years away, suggesting the possibility of a common origin. But these distances are not known with precision, and may be subject to revision.
Both the Trifid and Lagoon Nebulae are vast cocoons of interstellar dust and gas. These are stellar nurseries, actively giving birth to star formation. The Trifid and Lagoon Nebulae are summertime’s answer to the winter sky’s Great Orion Nebula.
For more about the science of this nebula, see our article on exploring the Trifid Nebula.
Bottom line: The Trifid is a famous summertime binocular object. Its name means “divided into three lobes.” If you view this nebula through a telescope, you’ll see why.

The Milky Way through the region of the tail of Scorpius and up into Sagittarius, photographed with it high in the sky from Australia. At bottom are the red nebulas of NGC 6334, the Cat’s Paw, and NGC 6357 (sometimes called the Lobster Nebula, for a “Paws and Claws” pairing). ..The clusters Messier 6 and Messier 7 are at left, below centre, with M7 lost in the star clouds of the Milky Way. The Galactic Centre lies at left centre. ..The Lagoon and Trifid Nebulas, M8 and M20, are at top left. Saturn is the bright star at top centre. The Dark Horse region of dark dust is at right, with the darkest part below being the Pipe Nebula, B78. ..This is a stack of 5 x 2-minute exposures at f/2.8 with the Rokinon 85mm lens, and filter-modified Canon 5D MkII at ISO 2500. Taken from Tibuc Gardens Cottage near Coonabarabran, Australia. ..The image could be turned 90° CCW to better resemble its orientation in the sky in which it was photographed in the southern hemisphere, This orientation matches the view in the northern hemisphere.
I used my camera to produce a night sky image to provide a location map for more detailed, higher resolution photographs of features that are present in this portion of the Milky Way.

Here's a collage of some common Deep Sky Objects and the Moon. All were taken using a Canon EOS 550D at prime focus of a 12" Goto Dobsonian and all are at the same scale.
I thought it might be interesting to see just how large these objects appear when compared to the Moon.
Exposures ranged from 1/500sec to 10 seconds.
Clockwise from top left:
Centaurus A galaxy, Keyhole Nebula in Carina, M22 globular cluster, Orion Nebula, Lagoon Nebula, Trifid Nebula, Omega Centauri globular cluster.
This image of the Lagoon Nebula (Messier 8) is from a single frame with a Canon 60Da camera and TeleVue NP101is apochromatic refractor.
I had a night with a forecast for clearer than normal transparency and better than normal seeing conditions. I had intended to spend the night imaging, but as I got my equipment ready and the sun began to set, clouds started rolling in (where did those come from? It was supposed to be completely clear and better-than-normal transparency.) It took a few hours for the skies to clear to the point where it was safe to image ... but the moon was about to rise. I only managed to get a few images before moonrise.
The image here is based on just a single frame of data.
I used my camera to produce a night sky image to provide a location map for more detailed, higher resolution photographs of features that are present in this portion of the Milky Way.
I don’t often use an 80mm lens for night sky photographs, but I am very happy with the level of detail in the output here. This focal length is midway between the wide angle (21-40mm) and mild telephoto (150mm and 250mm) lenses that I use more often.

M8 and Trifid Nebula as seen on June 25, 2011. Taken with an Unmodified Pentax K10D camera using the smc P-A* 300mm f4.0 lens at f5.6. I used an IDAS LPR-2 filter on the lens as well to help reject the inevitable light pollution. Subs were 16 frames of 5 minutes at 400 ISO (1 hour, 20 minutes). Used Losmandy GM8 mount guided by PHD with Orion SSAG on a Stellarvue SV70ED.
This image has been a long time coming. I originally captured the lights back in June and grabbed some darks at the same time as well. However, because the way that the software doesn't like the darks, it was really difficult to remove the amp glow that appears along the edge. After doing all the registration and calibration with darks that are at the same temperature as the lights, I was finally able to bring the FIT file into PI where I worked it over pretty aggressively.
As the corners were pretty badly distorted by coma, I've cropped them out as well as the amp glow.
This was the last of my efforts with using pef files. I've since gone over to dng.

Ambient temperature was 11 degrees Celsius or 52 degrees Fahrenheit. Wind was mild, and guide error RMS was 0.73". Sky was dark, and SQML was 21.77 at the night.
Obviously the small 4/3 sensor of my Olympus E-620 is not very good in astrophotography but I'm pretty happy with this one.

A wide view of Sagittarian trio of nebula.
Though really much more than a trio when viewed up close, the two most recognisable of the bunch are the Lagoon nebula at bottom and the Trifid Nebula at the top.

I called this image "Fantastic 4" in reference to HQ (superheroes) and the four sky elements crossing the center of the image:
Saturn (left side), Jupiter (center left), Sagittarius Star Cluster (center right) and Lagoon Nebula (right side).
Molecular clouds and the center of the Milkyway crossing up to down in the right side.
The Swan Nebula is on the top of the Milkyway and Ptolomy's Cluster is in the right down corner.
The Moon was in the right side of the Milkyway generating a flare in the image but after sometime the building cover its light.
It's a new composition.
After the lens fixing by myself, I could using my Meike 35mm f/1.7 again for astrophotography.

Chamei esta imagem de "Quarteto Fantástico" em referência à história em quadrinhos (super-heróis) e os quatro elementos do céu cruzando o centro da imagem:
Saturno (lado esquerdo), Júpiter (centro esquerda), Aglomerado de Estrelas de Sagitário (centro direita) e Nebulosa da Lagoa (lado direito).
Nuvens moleculares e o centro da Via Láctea cruzando de cima para baixo no lado direito.
A Nebulosa do Cisne está na parte de cima da Via Láctea e o Aglomerado de Ptolomeu está no canto inferior direito
A Lua estava no lado direito da Via Láctea gerando um "flare" na imagem, mas depois de algum tempo o edifício encobriu sua luz.
É uma nova composição.
Depois de arrumar as lentes sozinho, pude usar minha Meike 35mm f / 1.7 novamente para astrofotografia.
