Finally I got some good weather in Joinville to shot Sagittarius.
Although the moon was 41% illuminated, I've been able to do around 80 frames before the fog ruined the sky.

The Lagoon Nebula (M8), is a giant interstellar cloud in the constellation Sagittarius. It is classified as an emission nebula.
This LRGB image was taken way back in 2017 with the Skywatcher ED80 scope. I thought I would add it to Flickr as I am currently doing a Narrowband version from my home in northern Melbourne Victoria, Australia
The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) 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 is estimated to be between 4,000–6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulae, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006, four Herbig–Haro objects were detected within the Hourglass, providing direct evidence of active star formation by accretion within it.

First light with the ZWO ASI2600MC-P and I targeted the Lagoon and Trifid Nebula region of Sagittarius using the Williams Optics REDCAT. When looking in this region, you are looking into the center of the Milky Way, our galaxy. The Trifid Nebula (blue and red nebula) is near the top and is also known as Messier 20 (M20). The Lagoon Nebula is the largest nebula in this view and is also known as Messier 8 (M8). Several star clusters are also in view including Messier 21 (M21) to the upper left of the Trifid Nebula.
This was also the first test using the ProAstroGear Black-CAT Mount for autofocus on the Williams Optics Redcat using the ZWO EAF, worked like a charm.

Earlier in the night dense fog all along the coast had made it impossible to see the stars, so we drove some twenty miles east and stopped at a place with perfectly clear skies all the way to the horizon and no visible light pollution.

Messier 8
5,200 Light years away in the constellation Sagittarius is the Lagoon Nebula M8 (NGC 6523).
This vast emission nebula is home to the open star cluster NGC6530. The open cluster contains thousands of stars, most of which are hidden by the interstellar gas & dust that make up this awesome nebula.
The image is made up from about 2 hours of data using the Chile 2 telescope at Slooh.com stacked & processed with PixInsight.
a wide field shot of the Milky Way Core, with Lagoon and Trifid Nebula's shining bright in the centre. Canon 5Dsr with 70 -200mm L . 25 x frames of 100 sec each stacked to give around 40 mins of exposure. Love the dark dust here amongst all the billions of stars.
Nebulosa da Lagoa
Messier 8
Na constelação de Sagitário, se encontra um dos mais belos objetos do céu noturno. Essa gigante nuvem interestelar foi descoberta por Giovanni Battista Hodierna aproximadamente no ano de 1654. Situada a aproximadamente 5200 anos-luz da terra, a vista desta nebulosa através de um binóculo, apresenta apenas uma mancha clara e oval, destacando-se apenas o aglomerado aberto, sobreposto a nebulosidade.
Embora pareça cinza ao olho humano, em fotografias de grande exposição, a característica cor Rosácea, nos apresenta esse majestoso objeto. A região mais Brilhante da nebulosa foi descoberta por John Herschel, e ficou conhecida como a Nebulosa da Ampulheta, região com intensa formação estelar. Grande parte do brilho da nebulosa é devido a estrela 9Sagittarii, que fica próxima a região brilhante. É classificada como uma nebulosa de emissão, onde os gases ionizados, em especial o hidrogênio, emite radiação principalmente no comprimento de onda na faixa da luz visível vermelha.

This time out- shooting this scene- has been my most internally stirring experience under the stars this year. I teared up when I broke through the trees to see this at the shoreline.
If you get it, you get it. If you don't, you don't. But, I hope someday you get to :-)
2010 is coming to a close in a month. And, yeah, I'll get some shooting in before the year is over, but with the Winter clouds moved in, clear-Starry nights are a rare commodity.
So, the star shooting is few and far between.
I'm posting this as a re-edit. My initial post of this shot was done a few hours after it was shot. I was so excited to post it, I didn't spend much time processing it. The Winter months suck for shooting, but it's great to catch up on sleep and spend time editing, posting, and now for the first time, marketing!
I've got a showing coming up this December, so I had to go back and pick my favourite images and get them sent out to the printer. It's been a challenge to pick my favourite, my best representation of my work, and the pieces that have the best chance of selling. That's a challenging combo. But, in the process, I got to spend some time on this one, and I believe it is my favourite star shot I've ever taken. There's many close runnerups battling for 2nd, but, this one takes the cake.
Unfoooooooortunately, it's soft on the focus, :-/
It kills me.
My best shot and it's a tad soft on the focus.
But, it's been a hell of a motivation to battle that focus monster in subsequent shoots.
So, thanks everyone for your support, encouragement and following my work. All your comments have been encouraging and constructive.
Cheers to a good December for everyone :-)

A portion of the open cluster NGC 6530 appears as a roiling wall of smoke studded with stars in this image from the NASA/ESA Hubble Space Telescope. NGC 6530 is a collection of several thousand stars lying around 4,350 light-years from Earth in the constellation Sagittarius. The cluster is set within the larger Lagoon Nebula, a gigantic interstellar cloud of gas and dust. Hubble has previously imaged the Lagoon Nebula several times, including these images released in 2010 and 2011. It is the nebula that gives this image its distinctly smoky appearance; clouds of interstellar gas and dust stretch from one side of the image to the other.
Astronomers investigated NGC 6530 using Hubble's Advanced Camera for Surveys and Wide Field Planetary Camera 2. They scoured the region in the hope of finding new examples of proplyds, a particular class of illuminated protoplanetary discs surrounding newborn stars. The vast majority of known proplyds are found in only one region, the nearby Orion Nebula. This makes understanding their origin and lifetimes in other astronomical environments challenging.
Hubble's ability to observe at near-infrared wavelengths – particularly with Wide Field Camera 3 – have made it an indispensable tool for understanding star birth and the origin of exoplanetary systems. The new NASA/ESA/CSA James Webb Space Telescope's unprecedented observational capabilities at infrared wavelengths will complement Hubble observations by allowing astronomers to peer through the dusty envelopes around newly born stars and investigate the faintest, earliest stages of star birth.

Le nebulose Laguna (M8) e Trifida (M20) sono forse tra le nebulose più osservate e fotografate. E poterle ammirare nello stesso FOV è veramente bello e spettacolare.
Le condizioni meteo di quella sera non sono state eccezionali: cielo non molto trasparente e seeing mediocre, e per questi motivi ho scelto oggetti DS luminosi.
Volevo realizzare un mosaico con 2 pannelli acquisiti con le stesse condizioni di cielo quindi ho potuto utilizzare solo le circa 5 ore di buio disponibili.
Un'integrazione di 1h e 40min e la temperatura del sensore 26°C non possono certo permettere elaborazioni estetiche esagerate, quindi ho fatto quello che ho potuto e penso di aver raggiunto un discreto risultato.

Laguna (M8) and Trifida (M20) nebulae are perhaps among the most observed and photographed nebulae. And seeing them in the same FOV is really beautiful and spectacular.
The weather conditions that night were not exceptional: sky not very transparent and seeing middling, and for these reasons I chose bright DS objects.
I wanted to make a mosaic with 2 panels scanned with the same sky conditions so I could only use the approximately 5 hours of astronomical night available.
Integration of 1h and 40min and 26 ° C sensor temperature can not allow exaggerated aesthetic elaborations, so I did what I could and I think I have achieved a decent result.

A fleeting glimpse into the Southern Sky. Corona Australis (Bottom left) is a faint constellation just beneath Sagittarius and is home to the Corona Australis Molecular Cloud, a star-forming region 430 light-years away from our Solar System, adjacent to the nebulosity is the globular cluster NGC 6723, though close in the sky, NGC 6723 is actually ~28,000 light years further away. Imaging was quite a challenge as Corona Australis was only 14 degrees above the horizon at the time of imaging and the afternoon's storms were still clearing out. Thankfully enough subs were cloud-free to provide a decent SNR.

To celebrate its 28th anniversary in space the NASA/ESA Hubble Space Telescope took this amazing and colourful image of the Lagoon Nebula. The whole nebula, about 4000 light-years away, is an incredible 55 light-years wide and 20 light-years tall. This image shows only a small part of this turbulent star-formation region, about four light-years across.
This stunning nebula was first catalogued in 1654 by the Italian astronomer Giovanni Battista Hodierna, who sought to record nebulous objects in the night sky so they would not be mistaken for comets. Since Hodierna’s observations, the Lagoon Nebula has been photographed and analysed by many telescopes and astronomers all over the world.
The observations were taken by Hubble’s Wide Field Camera 3 between 12 February and 18 February 2018.

This may look like any other image of the Milky Way and it really is just that. The difference with this image is that it's made of 233 total images.
Last night while we were at Dead Horse Point and the sky was about as black as you can get, I had the opportunity to do something I have been wanting to do for a very long time.
This is a multi shot panorama/stitch that uses 23 various camera positions, 10 images in each position. Each of the 10 images were stacked for noise reduction and then each of the 23 stacked images were used to make the panorama/squareorama.
The detail in this image is extreme. With all my overlap, crop and adjust, this image will easily print 260x360 inches at optimum resolution.
I used a Sigma 50mm 1.4 Art lens with the following settings for each of the 233 images.

We are on our last night of our workshops and I have a feeling we will go out with a bang. I have a little surprise for the group tonight.
Here is a wide-field view of the star forming region named the Lagoon Nebula (Messier 8, M8) in the constellation Sagittarius. It encompasses the open cluster NGC 6530 (left of center) and the image also captures the globular cluster NGC 6544 in the lower left. From www.messier.seds.org/m/m008.html "One of the remarkable features of the Lagoon Nebula is the presence of dark nebulae known as 'globules' (Burnham) which are collapsing protostellar clouds with diameters of about 10,000 AU (Astronomical Units).

The Lagoon Nebula (catalogued as Messier 8 or M8, NGC 6523, Sharpless 25, RCW 146, and Gum 72) 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 is estimated to be between 4,000–6,000 light-years away from the Earth. In the sky of Earth, it spans 90' by 40', which translates to an actual dimension of 110 by 50 light years. Like many nebulae, it appears pink in time-exposure color photos but is gray to the eye peering through binoculars or a telescope, human vision having poor color sensitivity at low light levels. The nebula contains a number of Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued by E. E. Barnard as B88, B89 and B296. It also includes a funnel-like or tornado-like structure caused by a hot O-type star that emanates ultraviolet light, heating and ionizing gases on the surface of the nebula. The Lagoon Nebula also contains at its centre a structure known as the Hourglass Nebula (so named by John Herschel), which should not be confused with the better known Engraved Hourglass Nebula in the constellation of Musca. In 2006, four Herbig–Haro objects were detected within the Hourglass, providing direct evidence of active star formation by accretion within it. 20x8m=160m exposure.

The Lagoon Nebula (M8, Messier 8 or NGC 6523), is a giant interstellar cloud in the constellation Sagittarius. M8 is estimated to be between 4000 - 6000 light-years from Earth in the Milky Way Galaxy, and is classified as an emission nebula.
About this image:
Imaged in three key wavelengths of the electromagnetic spectrum of light (Hydrogen-Alpha, Sulfur-II and Oxygen-III), over a few nights (due to poor Astronomical seeing conditions, as a result of a very strong jet stream).
About Emission nebulae:
Emission nebulae are glowing clouds of interstellar gas which have been excited by some nearby energy source, usually a very hot star. The red light seen in this picture is glowing Hydrogen captured in the Hydrogen-Alpha (Hα) Infrared wavelength of light at 656nm. The blue light is from doubly ionized Oxygen ions (O2+) emitting at a wavelength of 500.7nm.
