NGC 2174, or the Monkey Head nebula, is an emission nebula in Orion located around 6,400 light years from Earth.
I am resist to turn the image 90º to see clearly the head... I really prefer how these clouds creates a better tridimensional effect and how the complete nebula increase his beauty if you are not identifying the "monkey head".
Close to 70 hours of image integration using my dual setup at the remote observatory located in Ager, Spain.

The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula) is a young open cluster of stars in the constellation Serpens, discovered by Jean-Philippe de Cheseaux in 1745–46. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope.
The pillars are composed of cool molecular hydrogen and dust that are being eroded by photoevaporation from the ultraviolet light of relatively close and hot stars. The leftmost pillar is about four light-years in length. The finger-like protrusions at the top of the clouds are larger than the Solar System, and are made visible by the shadows of evaporating gaseous globules. [Wikipedia]

The Vela Supernova Remnant is a large and complex structure in the southern sky that is the result of a supernova explosion that occurred approximately 11,000-12,000 years ago. It is located in the constellation Vela, which is Latin for "the sails," and is one of the closest and best-studied supernova remnants.
The Vela SNR is estimated to be about 800 light-years away from Earth and spans an area of approximately 8 degrees in the sky, making it one of the largest objects visible to the naked eye.
I have chosen the heart of the Vela as a subject for its high level of structural detail in this mega structure.
I have captured about 20h of data with RGB for the stars and Ha, Oiii and Sii for narrowband. Ha is map to Red, Oiii to blue and Sii to light blue which make the sulphur contribution appear purple in the image

Nebulosa da Cabeça de Cavalo e Nebulosa da Chama
[English Below]
Exercício (tentativa de registro prolongado), somando frames de dois dias (isto pela primeira vez), com a Nebulosa da Cabeça de Cavalo (Barnard 33) e a Nebulosa da Chama (NGC 2024). Foram empilhados 35 frames, totalizando quase 3 horas de exposição. Dentre outros fatores, infelizmente os registros foram um pouco prejudicados pela poluição luminosa da Lua e por algumas nuvens passageiras (não pude aguardar por dias mais favoráveis em razão de Órion já estar se despedindo do meu campo de visão nesta temporada). Também desta vez, senti necessidade de ter feito mais frames para alcançar melhor resultado, mas um novo período de noites com tempo fechado se iniciou. Fica para a próxima temporada. Ainda buscando avançar no processamento.
À direita da imagem, está a famosa Nebulosa da Cabeça de Cavalo. A Nebulosa da Chama está na parte inferior esquerda da imagem. Ambas se situam na constelação de Orion. A Nebulosa da Cabeça de Cavalo é uma nuvem de poeira opaca e é vista contra um brilhante fundo vermelho da nebulosa de emissão que se originou de uma nuvem de gás hidrogênio. A Nebulosa da Chama, é energizada por altos níveis de luz ultravioleta emanando da estrela supergigante azul Alnitak, mostrada logo acima dela, que é a estrela mais a leste no Cinturão de Orion.

====================================
Exercise (extended registration attempt), integrating two-day frames (this for the first time), with the Horsehead Nebula (Barnard 33) and the Flame Nebula (NGC 2024). 35 frames were stacked, totaling almost 3 hours of exposure. Among other factors, unfortunately the records were somewhat damaged by the light pollution of the Moon and some passing clouds (I couldn't wait for more favorable days because Orion is already saying goodbye to my field of vision this season). Also this time, I felt the need to have made more frames to achieve a better result, but a new period of nights with closed sky started. Stay for the next season. Still looking to advance in processing.
To the right of the image is the famous Horsehead Nebula. The Flame Nebula is at the bottom left of the image. Both are located in the constellation of Orion. The Horsehead Nebula is a cloud of opaque dust and is seen against a bright red background of the emission nebula that originated from a cloud of hydrogen gas. The Flame Nebula is energized by high levels of ultraviolet light emanating from the blue supergiant star Alnitak, shown just above it, which is the most easterly star in the Orion Belt.

Thor's Helment (NGC 2359) is an emission Nebula in zhe constellation Canis Major. It is about 15.000 lightyears away from earth and expands at a speed rate of ca. 25 km/s.
The light emitting bubble is exited by a Wolf-Rayet-Star which that emits hard radiation that blows the outer shells into the space.

Mandel Wilson 2, Dust Angel or Angel nebula, is made up of Integrated Flux Nebula (IFN).
According to Steve Mandel-Wilson, IFN are "high galactic latitude nebulae ... illuminated not by a single star (as most nebulae in the plane of the Galaxy are) but by the energy from the integrated flux of all the stars in the Milky Way".
Meaning... the combined light of stars along the Milky Way are reflected by these cosmic dust clouds that soar some 300 light-years or so above the plane of our galaxy.
It's amazing what myriad of small galaxies are in the background of htis picture....
It's a extremelly faint nebula on a large wide field, on the same frame it's possible to alocate 50 full moons.....

Hampshire Astronomical Group Picture of the Month October 2019
Featured on the BBC The Sky At Night website www.bbc.co.uk/programmes/p07qcd0m/p07qcbd1
An unusual group of galaxies (ARP 227) in the constellation of Pisces. Outer shells may have been created from gravitational interaction between galaxies. The largest galaxy is NGC 474. It is 100 million light years away, and about 250,000 light years across. The outer shells are extremely faint and have necessitated 1800s luminance exposures.

The galaxy pair Messier 81/82 is a very popular target for astrophotographers as it is fairly easy to image and contains many interesting features, such as IFN (Integrated flux nebula) and faint background galaxies. Additionally, M81 and M82 have been violently gravitationally interacting for almost 1.5 billion years. This gravitational push and pull most likely caused huge amounts of supernovae in M82’s starburst region, which are believed to ultimately fuel M82’s bipolar Ha-outflow.
This bipolar outflow or Ha-stream was also the main focus of our big collaboration! Having been interested in the galaxy pair for a long time, We found several deep images of the region and was especially interested in the H-alpha cap of M82 (See image). What intrigued us about this cap is that there is not really a visible connection between the main outflows of M82 and its cap. However, in some of the deepest images, it is possible to ever so slightly make out a dim connection between the main Ha stream and the Ha cap.
Since there exists no clear image of this region, we wanted to produce an image deep enough to reveal this exact region, which ultimately resulted in the beginning of this amazing collaboration of Astrophotographers from all over the world. In order to reveal the missing piece, we knew we had to go DEEP. Starting in February we had 6 people in the group, but the number quickly rose to now 17 people: 1 Editor, 1 person who gave us his Bortle 1 data for MSGR, and 15 photographers.
By mid-April we had 173h 34min of broadband data and 243h 04min of Ha data which had us confident in realizing our goal. With 416h 38min of total integration gathered on the target, of which 393h 10min (or over 16 days) were effectively used, this also marks the longest integration time ever on M81/82, and the longest one-panel integration time on Astrobin!

Special thanks to:
William, our editor and instructor on anything processing related and who also helped compose this text. He spent a staggering 40h+ hours processing the image you see here.
Carl, who was also a great help in anything technical related and who stacked all of our over 9000+ Broadband files and 3000+ Ha files, which took over 4TB of space and several days/weeks of processing.
Mark, who stacked all of our 3000+ Ha files which again took several days and gave us a second option for the Ha-stack
Prashant, who gave us his excellent Bortle 1 data that was used for MSGR
For a more technical overview of the editing, please refer to Will’s website: theastroenthusiast.com/collab-processing/
Finally, if you want to see our image in greater detail, feel free to go to Carl’s website, where the image is uploaded in full resolution ( 6000 x 4200 px), enabling you to explore the picture by yourself and being able to zoom in on every tiny detail!

Van den Bergh 14 & 15 along with SH2-202 in HaLRGB. This is a 2-panel mosaic from data I finished capturing a few months ago but hadn't had the time to sit down and process until now. I am properly proud of this image, more so than any of the others I have made since going remote. The stark contrast of the blue reflection nebula and the hydrogen alpha emission from the Sharpless cloud juxtaposed next to each other make this an extremely dynamic region.
I have not seen that many images of these objects in particular on Astrobin and thus wanted to shoot it in the hopes of inspiring others to make even better images of it in the future.

Dim Planetary Nebula at Cancer, really dim.
With a surface magnitude of 27 arc-sec-1, it was discovered in 1955 by George Abell.
It is estimated to be about 2,000 light years away.
This picture is the result of my longest integration time up to today, it's more than 90 hours of frame capture during the past 3 years.
The work desk was complicated due the different scopes and cameras used and the low signal captured.

A deep field attempt at capturing Markarian's Chain and surrounding Ha gas.
More than 92 hours of exposure in Ha, Lum and RGB did not reveal as much data as I expected but very happy with the deep field view of all the background galaxies in this fascinating group.
Imaged over three months in April, May and June 2025 at Los Coloraos, Gorafe, Spain. Unfortunately the weather was not kind and many of the frames were discarded due to clouds.
Markarian's Chain is a stunning string of galaxies located within the larger Virgo Cluster. From our perspective on Earth, these galaxies appear to form a gently curving line across the night sky, creating a beautiful cosmic alignment. It was named after Armenian astrophysicist Benjamin Markarian, who in the 1960s discovered their shared motion through space.
This "chain" is not just a visual coincidence; many of the galaxies are gravitationally interacting, influencing each other's shapes and movements. Notable members include the famous Messier galaxies M84 and M86, along with the "Eyes Galaxies" (NGC 4435 and NGC 4438), which show clear signs of a past close encounter.
Markarian's Chain offers a fascinating glimpse into galaxy evolution and interactions within a dense cluster environment. It's a popular target for amateur astronomers, showcasing a variety of galaxy types, from elliptical to spiral, all bound together in a grand cosmic dance.

Description
First image captured with the new dual rig configuration.
More than 56 hours of integration time. (Usually I am integrating 25 hours.. now dual rig :D is working ).
NGC 7635, also known as the Bubble Nebula, Sharpless 162, or Caldwell 11, is an H II region emission nebula in the constellation Cassiopeia. It lies close to the direction of the open cluster Messier 52. The "bubble" is created by the stellar wind from a massive hot, 8.7 magnitude young central star, SAO 20575.
The nebula is near a giant molecular cloud which contains the expansion of the bubble nebula while itself being excited by the hot central star, causing it to glow. (Desc creditcs: Wikipedia)

English Below:
Localizada na constelação de ARA (do latim O ALTAR), essa linda nebulosa foi descoberta por John Herschel em 1836, usando um telescópio refletor de 18 polegadas.
No topo da imagem podemos ver um belo aglomerado: NGC 6193, responsável pela nebulosa de reflexão dentro de 6188. Esse aglomerado está envolto em espessas nuvens de gás e poeira.
As estrelas mais quentes do aglomerado, duas gigantes do tipo O HD 150135 e HD 150136, (as estrelas brilhantes na imagem) são a fonte de iluminação da nebulosa de emissão NGC 6188.
Há uma interessante curiosidade a cerca de uma estrela em particular: HD 150136 é um notável sistema binário composto por uma enorme estrela do tipo O3 e uma estrela do tipo O6V que estão quase em contato uma com a outra. A colisão dos ventos estelares do par pode ser responsável pela emissão de raios X deste sistema estelar.
Além da nebulosa de emissão, é bom destacar os incríveis filamentos negros que aparecem na imagem. Muitos deles tem dezenas de anos luz de comprimento.
A distância estimada é de 4000 anos-luz, e toda a região de emissão está envolta em uma grande nuvem escura.
A região é densamente constituída por estrelas jovens, potencializando o brilho e os ventos nebulosos.O campo desta imagem tem o tamanho aproximado de 4 luas cheias e corresponde a cerca de 150 anos luz de diâmetro.
Os fortes ventos estelares das estrelas do aglomerado moldaram essa linda nebulosa. Comummente ela é chamada de “Batalha de Dragões de Ara”, devido ao formato parecido ao de dois Dragões duelando.

Located in the constellation ARA (from the Latin THE ALTAR), this beautiful nebula was discovered by John Herschel in 1836, using an 18-inch reflecting telescope.
At the top of the image we can see a beautiful cluster: NGC 6193, responsible for the reflection nebula within 6188. This cluster is wrapped in thick clouds of gas and dust.
The hottest stars in the cluster, two giants of the type O, HD 150135 and HD 150136, (the bright stars in the image) are the source of illumination of the emission nebula NGC 6188.
There is an interesting curiosity about a particular star: HD 150136 is a remarkable binary system composed of a huge O3-type star and an O6V-type star that are almost in contact with each other. The collision of the stellar winds of the pair may be responsible for the X-ray emission of this stellar system.
Besides the emission nebula, it is good to highlight the incredible black filaments that appear in the image. Many of them are tens of light-years in length.
The estimated distance is 4000 light-years, and the whole emission region is shrouded in a large dark cloud.
The region is densely constituted by young stars, enhancing brightness and cloudy winds. The field of this image is approximately 4 full moons in size and corresponds to about 150 light years in diameter.
The strong stellar winds of the cluster stars shaped this beautiful nebula. Commonly it is called "Battle of Ara Dragons", due to the shape similar to that of two dueling Dragons.

The Lambda Orionis Ring resembles a red flower and this image brings it together with the most famous rose in the winter night sky, the Rosette Nebula. Maybe it is the upcoming Valentine's Day to blame for my wild imagination. With this image I am hoping to give you the opportunity to spark your imagination and love, and why not, share it with your loved one!
This is a 3-panel mosaic made from old, lost data. Processed with the new Starnet version 2 in PixInsight, on a salvaged JPEG file. Some final touches done with love in Lightroom Classic 2022.
Technical Details:
Three hours of total exposure (3 x 60 x 60 sec frames) using an unmodified Canon 6D at ISO 1600 and a Samyang 135mm f/2 lens wide-open. The frames were taken under suburban skies (Bortle 5) on January 5, 2019. Tracked with a Star Adventurer Mini bundle. The image was down-sampled by a factor of two, to counteract for the low tracking quality present in the source data. More details at AstroBin.
