Here is a wide-field view of the Trifid Nebula, Messier 20 (M20) and the open cluster Messier 21 (M21) in the upper left. The word trifid comes from the Latin word trifidus which means “divided or split into three parts or lobes”. From Wikipedia - The object is an unusual combination of an open cluster of stars; an emission nebula (the lower, red portion), a reflection nebula (the upper, blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance. Focus got a little soft on this one.

A portion of the Milky Way in these summer days with the Dark Horse Nebula.
This nebula is one of the largest object of the deep sky. It is made up of many "small" dark nebulae mainly composed by interstellar gas clouds so dense to block light passing through.
Thanks to this simple mechanism we can detect the presence of such objects: by observing their silhouettes.
More extra info: the horse's back paw is usually called Pipe Nebula. And yet, in the belly of the horse lies a "small" (but fortunately visible in this photo) dark nebula with an "S" shape called Snake Nebula. Can you see them?

M8 - The Lagoon Nebula (NGC 6523) is a giant H II region in the constellation Sagittarius at 4,000-6,000 light years. The nebula contains several Bok globules (dark, collapsing clouds of protostellar material), the most prominent of which have been catalogued as B88, B89 and B296.
Messier 20 - "The Trifid Nebula" (above)
J2000 RA: 18h 02m 23s Dec: −23° 01′ 48″
NGC 6514, also known as The Trifid Nebula, is an HII region in Sagittarius discovered by Charles Messier on June 5, 1764.
The object is a combination of an opened cluster of stars, emission nebula, reflection nebula and a dark nebula that divide into three lobes this object.
This image is a "progressive stack" of images taken starting in 2019 and will be updated as new data is added. The goal is to obtain an image that is almost noise-free and rich in detail and nuance.

I knew I could capture the Lagoon Nebula and the Trifid Nebula. I was really hoping to catch all the nebulae clouds off to the right of the Lagoon Nebula (to catch a big nebula triangle) and boy, this approach sure worked great for that. My son and I like to call that area (appearing in the far right side) the Bear Claw Nebula but it's actually several other named objects. This is definitely a really interesting part of our night sky, that's for sure!
I captured this image using iTelescope's T8 telescope based in Sliding Spring, Australia in 2 nights - 5/17/2021 and 6/5/2021.
La Nebulosa de la Trífida, M20, es una de las nebulosas difusas de mayor tamaño aparente del cielo nocturno y sin duda una de las más bellas. En esta imagen, captada con el AP 305 mm Riccardi-Honders del observatorio de Daniel Verschatse en la Hacienda los Andes, la Trífida aparece inmersa entre las grandes y abundantes nubes rojas de hidrógeno que pueblan el centro del plano galáctico.
Haciendo honor a su nombre, en la Trífida se combinan tres tipos de nebulosas difusas. Las nebulosas de emisión se corresponden con las zonas de tonos rosados de M20 y están formadas fundamentalmente por grandes nubes de hidrógeno molecular que brillan por un efecto físico similar al que hace brillar una lámpara de neón. Las nebulosas de reflexión son las zonas con tonos azulados, en donde la luz de estrellas jóvenes cercanas, de intenso color azul, es dispersada y reflejada por diminutas partículas de polvo cósmico. Es el mismo fenómeno que se produce en la Tierra con la dispersión de la luz solar por parte de las moléculas de oxígeno y nitrógeno presentes en la atmósfera, y que genera el intenso color azul del cielo. A finales del siglo XIX algunos astrónomos utilizaron la hipótesis del "Nebulio", un presunto elemento químico encontrado en determinadas nebulosas que generaba una gran línea en el verde del espectro. Más tarde, en 1927, I.S. Bowen demostró que dicha línea pertenecía en realidad al oxígeno doblemente ionizado. Finalmente las nebulosas de absorción se corresponden con esa especie de vasos sanguíneos oscuros que parecen dar estructura a la Trífida y que son en realidad nubes moleculares que oscurecen la luz de los objetos brillantes que se encuentran detrás de ellas y en cuyo interior, mucho más frio que el medio que las envuelve, se incuban nuevas estrellas. La principal nebulosa de absorción de la Trífida, que la divide en tres secciones, está catalogada como Barnard 85.
Dentro de la Trífida se encuentra el cúmulo abierto de estrellas C 1759-230, con una edad de apenas 7 millones de años, en el cual destaca HD 164492A, una estrella gigante de espectro O7.5III, con una masa 20 veces mayor que la masa del Sol, y que es presuntamente la principal responsable de la incandescencia de la nebulosa.
Según revelan las observaciones realizadas recientemente en múltiples longitudes de onda, M20 es una región de formación estelar activa. Los astrónomos han encontrado numerosas evidencias de formación estelar de segunda generación que ha sido desencadenada por estrellas de primera generación. Dentro de M20 se observan muchos objetos característicos de los criaderos de estrellas, tales como jets ópticos, objetos protoestelares de infrarrojo medio y lejano, objetos estelares jóvenes infrarrojos y de rayos X, y objetos Herbig-Haro.
La distancia de M20 al sistema solar no es fácil de precisar y según las distintas fuentes sería un valor comprendido entre 1,7 kpc y 2,7 kpc. Un kpc es equivalente a 3.261 años luz.

The Trifid Nebula is a star-forming region in the Scutum spiral arm of the Milky Way. Discovered by Charles Messier in 1764, its name means 'divided into three lobes'. The object is an unusual combination of an open cluster of stars (out of frame); an emission nebula (red portion), a reflection nebula (blue portion) and a dark nebula (the apparent 'gaps' within the emission nebula that cause the trifurcated appearance; these are also designated Barnard 85). Viewed through a telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial summertime favorite of amateur astronomers, both observers and imagers alike.

For me, when I add a little imagination to the Trifid Nebula, I see a grumpy dog with a pink head and a blue body. I know it's really just nebula clouds but does anyone else see a Trifid puppy dog?
Not long after posting a similar image from this same area, I was pleased to see even better image data provided by iTelescope.net - in this case, coming from a high quality 20 inch telescope over many nights. In addition to providing access to their telescopes, iTelescope.net provides subscribing members with a combination of premium image sets (with the rights to use & post them) and webinars that show how to process them. Itelescope.net captured the images and I did the post-processing with Astro Pixel Processor, Photoshop, and Topaz Sharpen AI.

How many horses can you see in this image?
When I saw these two prancing horses, while scouting the sculptures in Borrego Springs, I immediately knew that I had to capture them with their galactic cousin, the Dark Hores Nebula.
The Dark Horse Nebula is a collection of dark nebulae near the galactic center that resemble the side silhouette of a prancing horse. It is part of the Great Rift, a dark gap that splits the band of the Milky Way in half, starting at the Northern Cross and extending all the way down to the “Teapot” of Sagittarius in the south.
The Dark Horse Nebula in this image is facing the prancing horse sculpture, like a smaller morror image. Its back is partially hidden by the head of the horse on the left, to make the answer to the introductory question a bit less obvious.
The sky art sculptures in Borrego Springs were created by the amazing artist Ricardo Breceda. Visit his stream to learn more about his work: ricardobreceda.com

Tracking was with an Ioptron star tracker.
Roughly 10 frames per field of view were stacked to reduce noise, then stitched to cover a wider field. This image is a small section of a larger project that I'm working on to create a large high resolution panorama of the central part of the milky way.

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.

The Trifid (M20) is a combination emission (red) and reflection (blue) nebula that is located in the constellation Sagittarius. It gets its name because the main section of the nebula is divided by dust lanes into roughly three parts.
Taken over two nights from a relatively dark site on the slopes of Palomar mountain, this image consists of 1022 sub-exposures that were each exposed for 5 seconds using an uncooled QHY5-III 178C camera and a Stellarvue SV80ST2 telescope (the latter operating at f/4.8 using a 0.8X reducer/corrector, total exposure integration time about 85 minutes). Using such short exposures greatly simplifies the image capture process since there was no need to guide the Celestron AVX mount that carried the scope and camera.
Image capture was done with SharpCap, image processing was done in PixInsight and Photoshop CC2015.
This photo is best seen against a dark background or in the Flickr light box at full size (1920 x 1242 pixels).

The Trifid Nebula, also known as Messier 20 (M20) or NGC 6514 resides near the center of our Milky Way galaxy in the constellation Sagittarius. It is a relatively young (less than one million years old) star forming region approximately 5200 light years from earth.
It consists of a reddish emission nebula caused by ionized hydrogen, a reflection nebula … the blue light reflected from nearby stars, and a dark nebula from obscuring dust clouds.
It actually gets its name (Trifid) from those dark nebula gaps which appear to divide it into three parts or lobes.
This is 94 minutes of 10 second images taken with the SeeStar telescope, processed in PixInsight, Nik Collection software, and Topaz sharpening.
