At a not-so-busy night, I went to dark mountains and tune my larger equatorial mount (Tak's NJP) with a telescope 1m focal length.
Guiding parameters for diurnal motion is not completed yet and star image is not true circular in this photo. The problem, however, gets gradually to converge, I think :-)

The Trifid Nebula (catalogued as Messier 20 or M20 and as NGC 6514) is an H II region located in Sagittarius. It was discovered by Charles Messier on June 5, 1764.[3] Its name means 'divided into three lobes'. 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; these are also designated Barnard 85). Viewed through a small telescope, the Trifid Nebula is a bright and peculiar object, and is thus a perennial favorite of amateur astronomers.[4]
The Trifid Nebula is a star-forming region in the Scutum spiral arm of the Milky Way.[5] The most massive star that has formed in this region is HD 164492A, an O7.5III star with a mass more than 20 times the mass of the Sun.[6] This star is surrounded by a cluster of approximately 3100 young stars.[7]

Messier 20 a.k.a Trifid Nebula
……………………………………………
Discovered in the 18th century by Charles Messier, the Trifid Nebula has an apparent diameter of about 25 light years, is located a little over 4000 light years from Earth, and can be observed in the Centaurus Arm of the Milky Way, at the edge of the constellation Sagittarius.
What is special about this deep sky object is that M20 is a combination of an open cluster (in the middle of the red area), an emission nebula (red area), a reflection nebula (blue area) and a dark nebula (those gaps in the star field). Unfortunately, this dark nebula does not stand out very well in the attached image because I had less than 3 hours of “photon collection”.

Check it out! This is the final version of the Messier 8 - The Lagoon Nebula / Messier 20 - The Trifid Nebula field imaging project. After several nights of capture, totaling 15 hours of exposure, I decided to start processing the datasets. There is so much going on in this image! All the reds in this image are recombined ionized hydrogen, a process triggered by intense ultraviolet radiation from nearby stars. Blues are reflected starlight from high-mass stars inside the nebula. Blacks are cold hydrogen regions, where starlight is obscured by the hydrogen cloud. Whites are the Integrated Flux Nebula (IFN) which are hydrogen, oxygen, and other metals that are being illuminated by the combined starlight of the overall galaxy. I captured this at Frosty Drew Observatory in Charlestown, Rhode Island. Mara Decesare assisted with data collection, alignment, and set up as part of the Frosty Drew summer internship project preparation.

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.
Neat summer target I've never imaged before because it is very low against my local horizon. The red portion is an emission nebula; the blue a reflection nebula; and the lobes are formed by a dark nebula -- all fueled by hot young stars.

Messier 8 and 20, the Lagoon and Trifid, appear so low in the northern sky that it has been a challenge for me to image them from home, where trees impinge on my horizon. This was captured at a Westchester Amateur Astronomers' star party last week. The Lagoon is a large emission nebula formed principally from hydrogen gas; the smaller trifid is a more complex structure featuring an emission nebula (red), a reflection nebula (blue) and a dark nebula which carves the red structure into its three petaled shape. Both structures are estimated to lie some 4-6,000 light years from earth.

Messier 20, or The Trifid Nebula is an unusual combination of dark, reflective, and emission nebula, plus an interesting open cluster of stars. It is located in an H II region in Sagittarius. The distance from out vantage is around 5200 light years away. It’s a little over 21 light years across, and is fairly bright at Magnitude 6.3. This makes it a fairly popular target with amateur astronomers.
I wanted to highlight the fine Ha filaments that surround this popular target. Ha areas are typically red in astronomical photos. The central area is bright, and tends to have a more washed out colour. On closer inspection, there is a terrific amount of detail running through the lobs. It looks like there are many dark cavernous channels intersecting this area. Each branching out into tiny filaments.

M20, la nébuleuse Trifide est une nébuleuse jeune et compacte située dans la constellation du Sagittaire.
•
La nébuleuse est à la fois une nébuleuse à émission et à réflexion, selon des zones bien distinctes :
- Nébuleuse à émission : une zone rose, voire rougeoyante qui correspond à une zone de formation d’étoiles.
- Nébuleuse à réflexion : une zone gazeuse bleue au Nord de la zone émettrice.
- Nébuleuse obscure : des filaments de poussières interstellaires parcourent la nébuleuse Trifide, lui donnant cet aspect de lobes, laissant penser à la forme d’un trèfle. Ces filaments sont des résidus de supernova.

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.

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.
This is the Trifid Nebula, a combination dark nebula and reflection nebula in the constellation of Sagittarius.
The blue gas and dust is highlighted by light reflected from the nearby star.
In the lower right is the open star cluster Messier 21.
This was created with 2 x 8 minute RGB images with an unmodded Canon 70D and Skywatcher ED100 Refractor, stacked in DSS and post processed in Lightroom.

Hoy quiero compartir una asombrosa obra arquitectónica que descubrí de manera fortuita durante mi último viaje a Extremadura: el Partenón de Don Benito. Lo sorprendente es que este monumento está dedicado al reciclaje, aunque pueda resultar difícil de creer.
No quise perder la oportunidad de hacer una visita nocturna para fotografiarlo junto al centro galáctico. Lástima que el cielo no era lo suficientemente oscuro como para tener más detalle en el cielo.
¿Qué os parece? Es cuanto menos curioso, ¿verdad?

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.
In order to trial the famous Blur/Noise/Star-Xterminator plugins for PixInsight, I decided to look at images I captured in July 2020 while testing my newly-acquired Nikon 600mm F4 lens.
Needless to say that these 3 scripts take your images to the next level especially when this is only 6 subs (3x 3' + 3x 2') at 1020mm F6.7 and autoguiding was struggling to control my NEQ6 mount!
Here is the cropped starless version, then tweaked using the usual PixInsight tools + BlurX and NoiseX.
I don't usually like starless images where I find stars do add to the richness of the field of view, but for once I could not resist ... O:)
A colorful shot I snapped of Messier 20 - The Trifid Nebula yesterday morning at Frosty Drew Observatory in Charlestown, Rhode Island, USA. The Trifid Nebula is a star forming region visibly featuring an emissions nebula (red), reflection nebula (blue), and a dark nebula. The Trifid Nebula is found in the constellation Sagittarius towards the central bulge of the Milky Way's galactic core, and resides at 5,200 light years distant.
