This deep-space image showcases two stunning nebulae in the constellation Auriga: the Tadpoles Nebula (IC 410) at the top center, and the Flaming Star Nebula (IC 405) toward the lower left.
IC 410, the Tadpoles Nebula, is an emission nebula located about 12,000 light-years from Earth. It surrounds the young star cluster NGC 1893, whose massive, energetic stars light up and shape the surrounding gas. The 'tadpoles' that give the nebula its nickname are dense streams of dust and gas about 10 lightyears long. They are assumed to be sites of star formation.
IC 405, the Flaming Star Nebula, lies in the lower left portion of the image. This beautiful mix of emission and reflection nebula is about 1,500 light-years away and is illuminated by the hot, massive star AE Aurigae. Its flowing, flame-like filaments of gas and dust give the nebula its name and striking appearance.
Set against a dense star field, this image uses narrowband imaging techniques to highlight different elements: hydrogen, oxygen, and sulfur. The result reveals both the structure and composition of these rich star-forming regions.
This image is a SHO combination with the classic gold and blue hues of the Hubble Palette

The Orion Nebula (also known as Messier 42, M42, or NGC 1976) is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion. It is one of the brightest nebulae, and is visible to the naked eye in the night sky. M42 is located at a distance of 1,344 ± 20 light years and is the closest region of massive star formation to Earth. The M42 nebula is estimated to be 24 light years across. It has a mass of about 2000 times the mass of the Sun. Older texts frequently refer to the Orion Nebula as the Great Nebula in Orion or the Great Orion Nebula
Portuguese:
A nebulosa de Órion ou nebulosa de Orião, também descrita como M42 ou NGC 1976, de acordo com a nomenclatura astronômica, é uma nebulosa difusa que se encontra entre 1500 e 1800 anos-luz do Sistema Solar, e situada a sul do Cinto de Órion. Foi descoberta por Nicolas-Claude Fabri de Peiresc em 1610 (anteriormente havia sido classificada como estrela - Theta Orionis). Existem muitas outras (fracas) nebulosas ao redor da nebulosa Orion e existem muitas formações de estrelas na região. A nebulosa Orion é, provavelmente, a nebulosa mais ativamente estudada do céu. O seu nome provém da sua localização na constelação Orion. Possui 25 anos-luz de diâmetro, uma densidade de 600 átomos/cm³ e temperatura de 70 K. Trata-se de uma região de formação estelar: em seu interior as estrelas estão nascendo e começando a brilhar constantemente. Há uma enorme concentração de poeira estelar e de gases nessa região, o que sugere a existência de água, pela junção de hidrogênio e oxigênio.
Here we have more data from the new set up in Spain that will soon be available for subscriptions.
It is always interesting to reshoot a previously imaged target to review where one's processing is.
I hope my current level shows a bit more of a natural look whilst still pulling out as much detail as I currently can.
Guess you will decide that though ;)

Explanation: An eerie blue glow and ominous columns of dark dust highlight M78 and other bright reflection nebula in the constellation of Orion. The dark filamentary dust not only absorbs light, but also reflects the light of several bright blue stars that formed recently in the nebula. Of the two reflection nebulas pictured above, the more famous nebula is M78, in the image center, while NGC 2071 can be seen to its lower left. The same type of scattering that colors the daytime sky further enhances the blue color. M78 is about five light-years across and visible through a small telescope. M78 appears above only as it was 1600 years ago, however, because that is how long it takes light to go from there to here. M78 belongs to the larger Orion Molecular Cloud Complex that contains the Great Nebula in Orion and the Horsehead Nebula.

As I mentioned dear viewers, I would probably end up processing this image several times before I was happy with it. This version (no. 7) is closer to the magic I felt beneath this starry sky.
Image capture by Carlos Araya, Chile, and processed by Martin Campbell using Pixinsight and Photoshop CC 2023. Image stack of 1.5 hours using a Canon 6D and a Nikon Nikkor 85mm F/1.4 lens at F/4 on a SW Star Adventurer.
Situated 7500 light years away in the ‘W’-shaped constellation of Cassiopeia, the Heart Nebula is a vast region of glowing gas, energized by a cluster of young stars at its centre. The image depicts the central region, where dust clouds are being eroded and moulded into rugged shapes by the searing cosmic radiation.

In the constellation Sagittarius, seemingly in the middle of the Milky Way, are two bright nebulae.
The Lagoon Nebula, the bright one lower in the frame, is a gigantic glowing cloud.
The Trifid Nebula (smaller, higher in the frame) is a composite of three nebula and an open star cluster. An emission nebula emits its own light (red), a reflection nebula (blue) and a dark nebula that looks like black lines on the glowing red (discernible by zooming in).
The Rebel T71 was modified for astrophotography.

A short window of clear skies on the 16th February, before clouds and rain rolled in, allowed me a longer imaging session on the beautiful Orion Nebula.
The nebula complex actually consists of two nebula Messier 43 (M43),the small beak-like feature on the left. This nebula is also referred to as De Mairan's nebula and it is joined to the second much larger fan-like nebula, M42, by a dense dust lane.
This dust lane is known as the northeast dark lane and is visible in the image.
Also visible top left is part of the reflection "Running Man" nebula - Sharpless 279 - running off the frame!!
The Orion Nebula complex is believed to lie just over 1300 light years distant and is estimated to be 24 light years across.
One of the very brightest nebula visible even to the naked eye as a fuzzy patch in the sword of the Orion.
This collection of neutral clouds of gas and dust, associated stars, ionized gases and reflection nebulae is a fine sight in any telescope.
Imaged with a guided Skywatcher Esprit 120ED fitted with a field flattener and a ZWO 2600MC camera.

Many thanks for looking!
The Heart Nebula, IC 1805, Sharpless 2-190, lies some 7500 light years away from Earth and is located in the Perseus Arm of the Galaxy in the constellation Cassiopeia. This is an emission nebula showing glowing ionized hydrogen gas and darker dust lanes.
The very brightest part of this nebula (the knot seen at www.flickr.com/photos/jrgibbs/28671076182/in/photostream/) is separately classified as NGC 896, because it was the first part of this nebula to be discovered.
The nebula's intense red output and its configuration are driven by the radiation emanating from a small group of stars near the nebula's center. This open cluster of stars known as Melotte 15 contains a few bright stars nearly 50 times the mass of our Sun, and many more dim stars that are only a fraction of our Sun's mass.

Interstellar dust clouds and glowing nebulae abound in the fertile constellation of Orion. One of the brightest, M78, is centered in this colorful view, covering an area north of Orion's belt. At a distance of about 1,500 light-years, the bluish reflection nebula is around 5 light-years across. Its tint is due to dust preferentially reflecting the blue light of hot, young stars. Reflection nebula NGC 2071 is just to the right of M78. To the left, and much more compact in appearance, the intriguing McNeil's Nebula is a recently recognized variable nebula associated with a young sun-like star. Deeper red flecks of emission from Herbig-Haro objects, energetic jets from stars in the process of formation, stand out against the dark dust lanes. The exposure also brings out the region's fainter pervasive glow of atomic hydrogen gas. (Text from APOD)

This region of the sky, in the constellation Monoceros, contains many different types of objects including Reflection nebulae (NGC2170), Hydrogen Alpha Emission nebulae (LBN999) and lots of surrounding molecular dust clouds. It is low in the sky from my latitude so more difficult to capture clean data and I also battled with intermittent clouds and a large number of satellite trails.

This is a wide-field image of Lagoon (M8) & Trifid nebulae (M20) in Sagittarius constellation. These nebulae are both star nurseries. The Lagoon nebula is emission nebula mainly composed of Hydrogen gas. The black focal spots in the nebula are protostar collapsing dust clouds called Bok globules. The nebula is brightened by two giant stars in the centre and the open star cluster NGC 6530 above it. In the other side, the Trifid nebula which is composed of Red emission nebula & Blue reflection nebula. It’s called trifid because the dark dust lanes are separating the nebula into three lobes. Its about 5,200 light years distance. Gear setup: WO Redcat51 f/4.9, Optolong L-Pro, ZWO ASI 2600 MC, iOptron Sky Guider Pro unguided, ASIair. Acquisition 20 x 180 sec subs, 20 Darks, 50 Bias.

Avevo iniziato nel 2015 ad acquisire queste immagini flic.kr/p/CCbNR7 , flic.kr/p/CCejHs , flic.kr/p/CCi68y per realizzare un mosaico con 5 pannelli. Purtroppo solo la 1° acquisizione è stata buona, mentre le altre hanno avuto vari problemi e il 4° pannello aveva poca integrazione quindi speravo di rifarmi quest'anno, ma non è stato possibile.
Malgrado ciò, ho unito i 4 pannelli ed ho tentato di elaborare il mosaico nel modo migliore possibile.
Il risultato (work in progress) mi è sembrato molto gradevole quindi lo condivido con piacere con voi.
I dati EXIF sono riferiti all'acquisizione del 4° pannello in data 20/08/2016

I started in 2015 to acquire these images flic.kr/p/CCbNR7, flic.kr/p/CCejHs, flic.kr/p/CCi68y making a mosaic with 5 panels . Unfortunately only the 1st acquisition was good, while the others have had various problems and the 4th panel had lower integration so I was hoping to solve this year, but it was not possible.
Despite that, I joined the 4 panels and attempted to process the mosaic in the best possible way.
The result (work in progress) seemed very nice so I share it with pleasure with you.

The Southern Cross is one of the most popular representations in the sky for observers in the southern hemisphere. Four stars give the constellation its characteristic configuration:
1. Acrux, at the foot of the cross, is the brightest of the four at magnitude 0.67 (and is the 13th brightest in the sky). Although a single star is visible in the image, Acrux is a sixfold system 321 light-years (average) from Earth.
2. Mimosa (below in the image), is second in order of brightness with a magnitude of 1.15. It is also known by the name of Becrux and is a spectroscopic binary system 278 light years from Earth.
3. Gacrux, the head of the cross, is third in order of brightness with a magnitude of 1.63. It is a red giant 88 light years from Earth.
4. Delta Crucis, also known as Imai, is the least bright of the quatern, with a magnitude of 2.70. Delta Crucis is in the process of evolving into a red giant.
An important group of star clusters enrich the view of this magnificent region of the sky, such as NGC 4755, known as The Jewel Box, under Mimosa. Caldwell 97 and Caldwell 100 can be seen above in the image on the Gacrux and Delta Crucis side. But surely what is most striking are the dark areas surrounding the foot of the cross. It is the most important of the dark nebulae in our sky, known as the "coal sack."
If you visit Argentina, don't miss the opportunity to go to a dark sky and look at the stars. After the astonishment, after feeling and assuming our enormous finiteness and contingency under that magnificent starry sky, look for the Southern Cross, the smallest, but the most notable of the 88 constellations in the sky. It is always visible, not hidden, and the sack of coal can be seen with the naked eye.

HFG-1 and Abell6 are both planetary nebulae in the constellation Camelopardalis. I love the shockwave on HFG-1 and the nearly perfect translucent sphere of Abell6. I'll need to come back and add data to this one though. This is only 21.5 hours of Ha-OIII-RGB data, just enough to get teased by this one.
