The Lagoon Nebula (M8) is a bright, vast star-forming HII region of hydrogen gas in Sagittarius. It lies low in the southern sky from my Idaho Falls vantage point. I love the Multiple Bok globules, bright central hourglass structure, and open star cluster (NGC 6530) to the right of center which give the nebula such an interesting appearance. This image was obtained with a Celestron Origin telescope ( 6 inch RASA) in EQ mode, the images stacked and processed in Pixinsight.
Júpiter y el Río lechoso.
En el centro de esta imagen se puede apreciar una “estrella” brillante de color blanco, resulta ser el planeta gigante gaseoso Júpiter, ubicada actualmente en la constelación de Ofiuco. A la izquierda lo acompaña la Via láctea, se le llamo así ya que al ojo desnudo se aprecia como una mancha blanca que atraviesa el cielo nocturno ya que nuestros ojos no tienen la capacidad de ver los colores de estas estructuras que están a miles de años luz, por eso, a través de la cámara se pueden desfigurar los colores reales de estas estructuras. El color amarillo-anaranjado son cientos de miles de estrellas viejas ubicadas hacia el centro galáctico, las nebulosas negras son nubes densas que se encuentran entre nosotros y el centro galáctico, al ser tan densas bloquean la luz que se encuentra detrás de estas nubes, los colores rojizos y rosados son principalmente regiones de formación estelar, regiones Hll, donde las estrellas masivas y brillantes ionizan el gas circundante haciéndolas brillar de estos colores.

Caption: A spectacular new NASA/ESA Hubble Space Telescope image reveals the heart of the Lagoon Nebula. Seen as a massive cloud of glowing dust and gas, bombarded by the energetic radiation of new stars, this placid name hides a dramatic reality.
The Advanced Camera for Surveys (ACS) on the NASA/ESA Hubble Space Telescope has captured a dramatic view of gas and dust sculpted by intense radiation from hot young stars deep in the heart of the Lagoon Nebula (Messier 8). This spectacular object is named after the wide, lagoon-shaped dust lane that crosses the glowing gas of the nebula.
This structure is prominent in wide-field images, but cannot be seen in this close-up. However the strange billowing shapes and sandy texture visible in this image make the Lagoon Nebula’s watery name eerily appropriate from this viewpoint too.
Located four to five thousand light-years away, in the constellation of Sagittarius (the Archer), Messier 8 is a huge region of star birth that stretches across one hundred light-years. Clouds of hydrogen gas are slowly collapsing to form new stars, whose bright ultraviolet rays then light up the surrounding gas in a distinctive shade of red.
The wispy tendrils and beach-like features of the nebula are not caused by the ebb and flow of tides, but rather by ultraviolet radiation’s ability to erode and disperse the gas and dust into the distinctive shapes that we see.
In recent years astronomers probing the secrets of the Lagoon Nebula have found the first unambiguous proof that star formation by accretion of matter from the gas cloud is ongoing in this region.
Young stars that are still surrounded by an accretion disc occasionally shoot out long tendrils of matter from their poles. Several examples of these jets, known as Herbig-Haro objects, have been found in this nebula in the last five years, providing strong support for astronomers’ theories about star formation in such hydrogen-rich regions.
The Lagoon Nebula is faintly visible to the naked eye on dark nights as a small patch of grey in the heart of the Milky Way. Without a telescope, the nebula looks underwhelming because human eyes are unable to distinguish clearly between colours at low light levels.
Charles Messier, the 18th century French astronomer, observed the nebula and included it in his famous astronomical catalogue, from which the nebula’s alternative name comes. But his relatively small refracting telescope would only have hinted at the dramatic structures and colours now visible thanks to Hubble.
The Hubble Space Telescope is a project of international cooperation between ESA and NASA.

Emission nebulae got brighter and bigger thanks to the application of the dual narrowband filter, though reflection nebulae got fainter and smaller.
Gegenschein looked not round but irregular on the frame taken with clear filter, but the irregular parts of Gegenschein looked reddish a bit on this frame taken with dual narrowband filter. It means that the irregular parts were not Gegenschein but faint integrated flux nebulae containing hydrogen-alpha light from stars nearby.
Equipment: Sigma 35mmF1.4 Art, IDAS NB12 Dual Narrowband Filter, and EOS R6-SP5, modified by Seo San on ZWO AM5n Equatorial Mount, autoguided with Fujinon 1:2.8/75mm C-Mount Lens, Pentax x2 Extender, ZWO ASI 174MM-mini, and PHD2 Guiding
Exposure: 7 times x 1,200 seconds, 8 x 240 sec, and 10 x 60 seconds at ISO 6,400 and f/3.2
site: 2,560m above sea level at lat. 24 23 21 South and long. 70 12 01 West near the peak of Cerro Ventarrones Chile
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.
This view of the Lagoon Nebula (M8) was captured from my backyard using a Celestron Origin telescope in alt-az mode with the raw images processed in Pixinsight.
The summer southern Milky Way over Reesor Lake in Cypress Hills Interprovincial Park, a Dark Sky Preserve. Only July 28/29, 2017, just after moonset with Sagittarius in the southwest, and Saturn just about to go behind the treeline. Wind rippled the water and prevented a reflection of stars and the Milky Way. Some airglow tints the sky.
This is a composite of four untracked exposures for the ground (mean combined to smooth noise) and four tracked exposures for the sky taken immediately afterwards (again, mean combined to smooth noise). The ground shots were 2 minutes each at f/2.8 and ISO 3200, The sky shots were 1 minute each at f/2 and ISO 1600. All with the 20mm Sigma Art lens and Nikon D750. The tracker was the Star Adventurer Mini.
This is the Milky Way core and a bonus meteor over the peaks and valleys at Saskatchewan River Crossing, in Banff National Park, Alberta. At left is the sharp peak of Mount Chephren and the Mistaya Valley. At right is the Howse Pass route over the Continental Divide. Below is the North Saskatchewan River flowing out of the Rockies. In the sky are the galactic core and starclouds in Scutum and Sagittarius toward the centre of our Milky Way Galaxy.
The rich collection of nebulas and star clusters toward the core show up well, including the Lagoon Nebula (most prominent), the Messier 24 starcloud above, flanked by the M23 and M25 star clusters, and the M17 (Swan) and M16 (Eagle) nebulas above it. At top is the Scutum Starcloud wirh the Messier 11 star cluster.
The constellation of Capricornus is just contained within the frame at left.
At centre is a well-placed random meteor that just happened to appear during the shooting of one of the sky frames. The meteor displays the usual green to red colour transition as it descends into the atmosphere, from the high-temperature ionization of oxygen and nitrogen molecules. Another bonus of sorts are the bands of green airglow, another form of atmospheric glow, caused by chemical fluorescence.
So this is a busy sky filled with sky phenomena both near and far.
Technical:
This is a blend of tracked (for the sky) and untracked (for the ground) exposures:
- A single untracked 2-minute exposure for the ground, with Long Exposure Noise Reduction on.
- A stack of 4 x 1 -minute tracked exposures for the sky, with LENR off
+ A single 1-minute exposure with the meteor was blended and masked in to contribute just the meteor. But it's in the place in the sky where it actually appeared.
All were wide open at f/2 with the RF28-70mm lens at 28mm on the stock Canon R5 at ISO 800. On the MSM Nomad star tracker. Taken from the Howse Pass Viewpoint just as the Moon was setting so the sky was fairly dark. Adobe DeNoise AI applied to the ground image. I would have taken more ground frames to stack, but time was tight between the Moon setting and getting the Milky Way before it moved any farther west.

The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) is a giant interstellar cloud or emission nebula in Sagittarius.
This image was taken with the Celestron Origin telescope. The nearly full moon had risen in the east but I thought I would give it a go. The image consists of 61 ten second images for just over 10 minutes of total imaging time. Stacking and processing was done in the Origin and minor tweaks in Photoshop.
Aujourd’hui direction le bulbe de la Voie-Lactée. Cette région renferme une grande quantité d’etoiles, de nébuleuses, d’amas stellaires et autres objets du ciel profond.
•
Du bas vers le haut, on peut voir :
- la nébuleuse de la lagune en bas à droite (rouge). Cette nébuleuse diffuse est un immense nuage d'hydrogène et de poussières éclairé par une supergéante bleue. La taille de la nébuleuse est d'environ 110 années-lumière, et est distante de 5 000 années lumière de la Terre : elle occupe dans notre ciel, un diamètre trois fois plus important que celui de la pleine Lune.
- Juste au-dessus de la lagune se trouve M20 ou nébuleuse trifide. La trifide est une nébuleuse à réflexion et à émission. N’hésitez pas à aller voir mon post du 16/06/20.
- Au centre de l’image, sur la gauche, se trouve une zone chargées d’étoiles. Il s'agit de M24 (ou nuage du Sagittaire), vaste nuage galactique composé d'étoiles et de gaz interstellaire.
- Plus au-dessus encore, se trouve deux nébuleuses (rouges également). Celle du bas est M17 (ou nébuleuse Oméga), nébuleuse en émission située à environ 5 500 années-lumière de la Terre. Celle du haut est la nébuleuse de l’aigle (M16). (Voir mon précédent post).

On a night where the primary plan (for great night photography) went to pot, I decided to improvise with a plan to head south to the Spanish Peaks with good friend, Jon Blake.
We were hoping for some more cooperative weather (than was predicted up north) and with a big 84% full moon setting at 3:30 am, I figured we had a chance for a good composite image. I was hoping for some good light from the moon just as it set on the horizon followed by some good dark sky shots of the milky way afterward.

Astro-landscape image of the Lagoon and Trifid Nebula over Steens Mountain in SE Oregon. It was meant to be a Deepscape, but life happens..
I didn't think this image was going to come together. The clouds were supposed to dissipate by 8:30pm and then clear skies for the rest of the night so I could collect lots of data on the nebula to make them really stand out. That is NOT what happened.
Not only did the clouds not clear at 8:30pm, but a thunderstorm rolled through to the west. My lightening app showed lightning and rain heading my way, so I covered up my tracker and camera and ducked into the car. Put "Ridin the Storm Out" on the radio and cranked it up. As it turned out, the storm skirted past me to the west and I neither got wet nor electrocuted. The clouds never fully dissipated, but I got enough images of Lagoon and Trifid peaking through to make an image.

The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. The Lagoon Nebula was discovered by Giovanni Hodierna before 1654 and is one of only two star-forming nebulae faintly visible to the eye from mid-northern latitudes.

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.
During my May vacation, the weather in central Europe was as foul as it can get. Nothing but wind and rain in the forecast for a whole week.
After checking all my options, I decided to drive to central Italy, as Tuscany was the closest region, where the forecast at least showed a chance for clear skies.
I took the decision in the early morning and an 8 hours drive was needed to get there. My pre-planning was therefore marginal. After finding a place to sleep and having a (great) dinner, I headed to this famous spot and captured the rising Milky Way over Podere Belvedere - probably the most photographed farm in the region, if not in whole Europe.
I was very surprised that I was the only photographer doing nightscapes there and I took the chance to create this extensive focus stack. As light pollution was rather bad, I used my light pollution filter to increase contrast.
After finishing this shot, I headed to the famous group cypresses, where I found a real frenzy of activity. While setting up my gear next to some local astrophotographers, they started teasing me that I was late for the party. When I told them that I had been shooting the Milky Way over Podere Belvedere first, they chuckeled even more and told me that it was impossible to capture a decent Milky Way shot from there. Instead of arguing, I just showed them the RAWs on my cameras LCD. Now the chuckles were gone and they said "Oh, we'll have to try that as well..."
Lesson learned:
Sometimes, if you come to a place as a clueless outsider without extensively researching it, you might succeed in capturing a composition, because you had no idea that it was known to be impossible.

The Scutum Starcloud (top) and Small Sagittarius Starcloud (midway down the Milky Way) stand out. The main Sagittarius Starcloud just above the horizon and town skyglows is dimmed by its low altitude and some smoke in the air this night. Between the two Sagittarius starclouds is the pink Lagoon Nebula. Several Messier star clusters popular the field as well. The "Teapot" asterism that marks Sagittarius stands out fairly well.

This is a blend of tracked and untracked exposures:
- one 4-minute untracked exposure for the ground at f/4 and ISO 1600,
- followed by a stack of 4 x 1-minute exposures for the sky, each at f/2 and ISO 400. All with the Nikkor 20mm S lens and Nikon Z6III camera. On the MSM Nomad tracker.
Taken July 8, 2024 as part of a set of images demonstrating untracked vs. tracked exposures. Adobe DeNoise AI applied to the ground image largely to eliminate the hot pixels, as I did not use Long Exposure Noise Reduction on this warm night to speed up the shooting.
This is a reshoot of an image I had already done over a month ago. In the original, I had some optical aberrations due to improper spacing of my camera and coma corrector in my optical train, as well as fighting a mix of thin cloud which also caused me some guiding issues. This time, my optics were perfect, skies clear, and tracking was spot on!
Located at a distance of 5200 LY from Earth in the direction of the constellation Saggitarius, the Lagoon Nebula is one of the many star forming regions in that part of the sky. The giant stars within the nebula produce radiate trmendous amounts of UV radiation which ionizes the gas and causes it to glow. It's visible to the naked eye as a bright spot standing out of the Milky Way, but looks very distinct in binoculars.

My 1st attempt at these 2 beautiful Nebulae , M20 TRIFID NEBULA on the left side and M8 LAGOON Nebula on the right. I was trying for the Lagoon and was lucky with the lens I used that I managed both in 1 x go. 126 x light frames 17 x dark frames and 32 flat frames, lights were 30 secs each so a total of 1 hour 3mins of data captured and stacked in Sequator software. Canon 60D and Asahi Takumar 135mm f 3.5 old mf lens on a Star adventurer 2i tracker. Very damn happy with this 1st attempt.
The galactic centre area of the summer Milky Way in Sagittarius and Scorpius low over McGregor Lake reservoir in southern Alberta on a summer night. Jupiter is the bright object at right to the west of the Milky Way; Saturn is dimmer left, east, of the Milky Way. The sky is blue from the lingering summer solstice twilight. The pink Lagoon, Swan, and Eagle Nebulas show up well, despite this being an unmodified camera. Unfortunately, so does light pollution from towns to the south, primarily Lethbridge. The long exposure smooths the water and blurs the reflections which come from one of the static images. The most southely Messier objects, the star clusters M6 and M7, are just visible in and below the band of clouds.
This is a blend of untracked exposures (4 x 1 minute) for the ground, and 4 x 1 minute tracked exposures for the sky, all at ISO 800 with the Nikon D750 and Sigma 24mm lens at f/2.2. Stacking exposures with a mean blend mode smooth noise; the tracking ensures pinpoint stars, but ensuring a sharp foreground requires shooting those exposures with the tracking motor off and blending them later. The tracker was the Sky-Watcher Star Adventurer. LENR employed between exposures.
This new NASA/ESA Hubble Space Telescope image shows the Lagoon Nebula, an object with a deceptively tranquil name. The region is filled with intense winds from hot stars, churning funnels of gas, and energetic star formation, all embedded within an intricate haze of gas and pitch-dark dust.

The bright area left of the center of this image is the Small Sagittarius Star Cloud or M24. It is fairly large on the sky, so I decided to try shooting it with the Nikon D5100 instead of through the telescope. When I realized how many objects were nearby, it seemed like a good idea to expand the field of view.
There are 10 Messier objects present. These include four bright emission nebulae. From top to bottom, those are M16 (Eagle Nebula), M17 (Swan or Omega Nebula), M20 (Trifid Nebula), and M8 (Lagoon Nebula). Star clusters M25 and M23 are to the left and right, respectively, of the star cloud. Star cluster M21 is just above and left of the Trifid Nebula. M18 is a small star cluster between M17 and M24. In the lower left corner, globular cluster M28 is in view. There are many other NGC and IC objects present, along with dark clouds that represent areas dense with dust which blocks the view of background stars.
This is a stack of 47 60s exposures at a focal length of 90 mm and ISO 2000 from Mt. Pinos, CA. Dark, flat, and bias frames were applied in PixInsight, with registration, stacking, and additional processing in that program. Final touches in Photoshop.

The Lagoon Nebula is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula and as an H II region. (Wikipedia)
I photo it during my visit to Namibia in June 2019, I manage to capture only the Ha subs, hoping to get the RGB from home. For now Im uploading the Ha only version.
Photo details:
Ha -12 x 5min each frame = 60mi
Total exposure - 1 hour
Telescope: ASA 12'' F3.6
Mount: DDM 85 Unguided
Camera: FLI 16200 Mono

Milky Way 2016 June 08, Hungary, Székesfehérvár 14x120s, CANON EF1.4 50mm, (f3.2) iso 800, (CANON M.)
The Galactic Core of the Milky Way rises above snow covered Mt. Katahdin and the other mountains of northern Maine. I shot this at 50mm so the mountains wouldn’t be just tiny specks, and to get a lot of detail in the Galactic Core.
At 50mm the pink nebulae around the core also become much more visible, including the Lagoon Nebula (largest pink spot center-left in the sky), as well as the Trifid Nebula, Eagle Nebula, and Swan Nebula. The bright star Antares and others around the Rho Ophiuchi cloud complex are visible in the upper right.
Nikon Z 6 with NIKKOR Z 50mm f/1.8 S lens @ f/1.8, ISO 6400. Star stack of 20 x 4 second exposures for sharp stars and low noise. I stacked the raw files in Starry Landscape Stacker (Mac only but you can do this with Sequator on Windows), then did some basic edits on the resulting file in Lightroom Classic, and then final edits for really bringing out detail in the Milky Way in Photoshop.
The few reflections of stars in the open area of water on the lake blurred far too much with the stacking, and treating the water as the "sky" in Starry Landscape Stacker didn't work because there simply aren't enough stars in the reflection for the software to properly align the reflections. So to get a lower noise version of the reflections I manually aligned and stacked 10 of the sky photos in Photoshop, moving the layers a few pixels at a time to get the reflections to line up between shots. I could have used all 20 shots but 10 was more than enough for just the little bits of reflection that I needed. Averaging that stack resulted in a lower noise version of the reflections, and I was able to mask them into the final shot with a combination of using the lighten blend mode and manual masking of just the reflected starlight.

The Milky Way as seen from rim of Haleakalā Crater on a perfectly clear night. The mountain in the distance near the lower right corner of the picture is Mauna Kea.
The inset rectangle shows the area seen in this zoomed-in photo of the Lagoon Nebula and the Trifid Nebula. A version of this photo, but without the inset rectangle can be seen here.
Seen at Lake Sonoma early in the morning in June, about an hour before first faint hints of daylight.

I finally managed to finish processing this beauty. This was a complicated capture with wind, gear malfunctions, and of course haze. This area of milky way doesn't stay above the horizon very long either (at least in this part of the world) limiting the exposure time.
I managed to get 23 7 minute frames over two nights totalling to just under 3 hours exposure time - much less than what I was hoping to accomplish. But I was able to extract reasonable amount of data from the stacked image.
You can clearly see the central region of milky way with M8 Lagoon Nebula (purple blob in the left centre), M20 Trifid Nebula just above it (pale blue). In the top left corner you can see M16 Eagle Nebula and M17 Omega Nebula.
Rho Ophiuchi Cloud Complex covers the right hand side of the image. The Dark River Nebula (B44) extendes all the way from Milky Way to this cloud complex.
And finally Saturn shines brightly over the black dust clouds in the centre of the image.
:-) Love them stars
Just got back from a weekend of shooting stars, and man-o-man, I am tired! Gonna be rough waking up for work tomorrow.
The first night the clouds were fickle. On the drive out to this spot I was worried we were going to be completely buried under clouds, but the sky cleared out and the stars began to shine.
But then as we began shooting, it became apparent thin clouds were continuously passing overhead, and did that the entire night.
On one hand, it was frustrating to work out a composotion for 20 minutes, get it all dialed in and then go to take the shot, only to find out fingers of clouds had covered much of the sky. But on the other hand, the wispy cloud layer does add an interesting element between the landscape and stars.
My friend Jon and my lovely Valorie joined me on this weekend. We all had a good time. Jon and I shot stars, Valorie read books, hung out, and provided incredible support. As always, I'm am very thankful for her backing me in this ludicrous passion of photography in the middle of the night in far out places. (and she reminds me she cuddled me in the tent when I crawled into the sleeping bag at 3am both nights :-) [she also makes a killer stir fry over a fire!]
Sadly, all light in the clouds is sourced from light pollution about 50 miles away.
I've got a hefty take of starry pictures from this trip, so please come back often to see what's new.
OH- something new and exciting, you can see my work in a different format here:
