The Clampshell Nebula (Sh2-119) is a large emission nebula located about 2,200 light-years from Earth, in the constellation Cygnus. It lies just 3° east of the famous North America–Pelican complex and, perhaps because of this proximity to such a well-known object, it is not among the most frequently photographed regions of the sky. In reality, it is a highly fascinating area, made particularly striking by the contrast created by a dense network of dark dust in its southern portion. Near the center of the field shines, like a pearl, the star 68 Cygni: its closeness is only apparent, as it is actually more than twice as far away as the nebula.

I have photographed the Heart Nebula before, and was always curious and interested in the little appendix in the corner. It can easily be overlooked when looking at the much larger and impressive details of the Heart Nebula (See flic.kr/p/2qgwVE8). This time, I decided to spend some quality time imaging NGC896; I love the intricate patterns of dark dust clouds interspersed with brighter regions full of young stars.
In total, I've managed to acquire 27 hours of narrowband data, with both the Optolong L-Ultimate (3nm Ha & Oiii) and with the Antlia ALP-T 5nm Ha & Oiii filters.
I used my William Optics FLT 132 with the Flat8 0.72x reducer, the ZWO ASI2600MC Pro camera, on an AM5 mount with ASIAir Plus. Processed with PixInsight + Affinity Photo 2.

I hope you like it and perhaps be inspired to spend some time imaging this somewhat overlooked but beautiful nebula.
Thanks for looking.

===== From Wikipedia ====
The Fish Head Nebula, or the Northern Bear Nebula, is part of a large star forming system of gas and dust located along the Perseus spiral arm of the Milky Way. The nebula is located in the Constellation Cassiopeia, approximately 6,000 light-years from Earth and is adjacent to the much larger Heart Nebula. The brighter region of the nebula is designated NGC 896 and is the home to many young and large stars. These stars radiate high amounts of ultraviolet light. This UV radiation excites the surrounding gas and causes it to shine at a high brightness.

IC 443, also known as Jellyfish Nebula, is a supernova remnant located at 5,000 light years in the constellation Gemini. This supernova has created neutron star CXOU J061705.3+222127, the collapsed core of the exploded star; these neutron stars have a density of 400 million tons per cubic centimer - in other words, the mass of about 1’800 Great Pyramids of Giza fitted in a cube with one centimer side.
Near the top right corner, a small planetary nebula called HoCr1 (Howell-Crisp 1) can be seen. It was found in 2006 by amateur astronomers Michael Howell and Richard Crisp - always fun to find objects we were not expecting in a photo…

Working on a Heart and Soul Mosaic, this is 2 of the panels, need to finish the 3rd panel which will include the rest of the Soul Nebula. This is the h-alpha integration shot with an Optolong L-enhance filter on a modded Nikon D5300, roughly 8 hours of integration per panel. Working on getting the Oiii for the second panel so I can then do the bi-color combination for the 2 panels. LOTS AND LOTS of work for this kind of stuff, some of the hardest astro I've done.

La nebulosa Messier 78 (también conocida como M78 o NGC 2068) es una nebulosa de reflexión en la constelación Orión. Fue descubierta por Pierre Méchain en 1780 e incluida por Charles Messier en su catálogo de objetos ese mismo año.
M78 es la nebulosa difusa de reflexión más brillante de un grupo de nebulosas que incluye NGC 2064, NGC 2067 y NGC 2071. M78 es fácilmente visible en pequeños telescopios como una mancha difusa e incluye dos estrellas de magnitud 10. Estas dos estrellas, HD 38563A y HD 38563B, son responsables de hacer la nube de polvo en M78 visible al reflejar su luz. (Wikipedia)

Essa densa nuvem de poeira estelar é iluminada por estrelas jovens.
É uma região em colapso, onde muitas outras estrelas estão nascendo.
Quase sempre esquecida, essa linda região da constelação de LUPUS é muitas vezes preterida por estar muito próximo da região do escorpião, amplamente fotografada por nós, astronomos amadores.
Inclusive o trabalho de pesquisa para esse breve artigo foi árduo devido as poucas informações a cerca desse objeto.
Conhecido como Sandqvist 14 ou Lupus 3, está localizada a 600 anos-luz da terra. (uma das nebulosas escuras mais próximas da terra)
Quase toda a nebulosidade é formada por poeira e gás e se estende por centenas de anos-luz.
As estrelas jovens, e azuis do centro, foram formadas nessa nuvem cósmica, que quando suficientemente aquecida, sua radiação e fortes ventos, varreram a nebulosidade de sua frente, podendo enfim brilhar de seu berço caótico de escuridão.
Esse processo de formação estelar é lento, e provavelmente essa paisagem celestial não irá se alterar durante muito tempo.
Os primeiros astrônomos que observaram as nebulosas escuras pensavam que esses trechos de céu mais escuro eram vazios. Porém a partir de 1900 Edward Emerson Barnard observou e fotografou mais de 200 nebulosas escuras
Também são conhecidas como nebulosas de absorção, pois as partículas frias e densas de poeira absorvem e dispersam a luz que passa pela nuvem.
This dense cloud of stellar dust is illuminated by young stars.
It is a collapsing region, where many other stars are being born.
Almost always forgotten, this beautiful region of the constellation LUPUS is often overlooked because it is very close to the region of the scorpion, widely photographed by amateur astronomers.
Even the research work for this brief article was arduous because of the little information about that object.
Known as Sandqvist 14 or Lupus 3, it is located 600 light-years from Earth. (one of the darkest nebulae closest to Earth)
Nearly all of the cloudiness is formed by dust and gas and stretches for hundreds of light-years.
The young, blue stars of the center were formed in this cosmic cloud, which when sufficiently heated, its radiation and strong winds, swept the cloudiness of its front, and could at last shine from its chaotic cradle of darkness.
This process of star formation is slow, and probably this celestial landscape will not change for long.
Early astronomers who watched the dark nebulae thought that these stretches of darker sky were empty. However from 1900 Edward Emerson Barnard observed and photographed more than 200 dark nebulae.
They are also known as absorption nebulae, because the cold, dense particles of dust absorb and disperse light passing through the cloud.

The Soul Nebula is an emission nebula located in the constellation Cassiopeia, 7500 light years from Earth. It forms a famous pair with the neighbouring Heart Nebula which I posted recently. The Soul Nebula is sometimes also known as the Embryo Nebula (I always think it looks like a 12 week ultrasound of a baby ☺️) or IC1848, which is a designation used for the open star cluster embedded within the nebula.
The Heart and Soul Nebulae complex spans an area about 300 light years across and is a vast star-forming region illuminated by the light of the young stars surrounded by star-forming clouds of dust and gas. The two large clouds are separated by only 2.5 degrees and physically connected by a bridge of gas. The stars in the region are less than a few million years old and are only beginning their life. For comparison, our Sun has been around for almost 5 billion years.
This was taken over 3 nights from the garden in Wales and comprises 189 separate images, each 3 minutes long. It is then calibrated with another 150 images to provide a final stacked image that is processed for colour etc.

LDN 1400 is a vast region, which also includes the dark nebulae Barnard 8-9, 11, and 13, which hides the object SNR G150.3+4.
By studying the data and with their fantastic collaborative image, Nicolas Martino and Yann Sainty discovered the remnant of a supernova composed of a large area of hydrogen and filaments of O3.
I've been working on this project for over two years and knew full well that it would require a rather long integration.
Today I'm showing you the first result with the dark nebulae of the constellation Giraffe mixed only with oxygen.

The Lagoon Nebula M8 is a diffuse nebula in the constellation of Sagittarius. It is one of the brightest regions of the sky and is visible even with the naked eye in fairly clear and dark skies.
One of the main features of the Lagoon Nebula is the presence of small black spots known as Bok globules, which are protostellar clouds.
The brightest region of the nebula, in the center of the Lagoon, is known as the Hourglass Nebula and is a region of intense star formation.
The Trifid Nebula M20 on the right is a well-known star-forming region and is made up of three different types of cosmic clouds: reddish emission nebulae, blue reflection nebulae (produced by dust that reflects starlight), and dark nebulae, including the central one divided into three dense bands of dust, hence the name Trifid.
NGC 6559 on the left has both red emission regions and bluish reflections
This image is the result of 2 shots, one broadband and one narrowband, a combo of 2 filters l-quef and l-para to amplify the signal and the detail of the nebulae

In May, I was really lucky with the astro-weather around the new moon. The nights were quite short, but I still wanted to make good use of them. Unfortunately, the view from my home is a bit restricted due to large trees in the garden, which greatly limited the selection of objects in May. However, the region in this image was one of the few that was visible all night, allowing me to collect over 27 hours of data in total.
The image shows the emission nebula SH2-157, also known as the "Lobster Claw Nebula," which stands out due to its characteristic shape and red color. Next to it is the impressive bubble nebula NGC 7635, the "Bubble Nebula," formed by the strong stellar winds of a hot, massive star. Both nebulae are located in the constellation Cassiopeia and together create a fascinating celestial object.

This images has been cropped a little bit to highlight the galaxy.
IC 1805, surnommée la nébuleuse du Cœur, est une nébuleuse en émission située à environ 6 500 années-lumière.
dans la constellation de Cassiopée. Elle couvre un champ d'environ 60 minutes d'arc, ce qui correspond approximativement à 200 années-lumière.
La nébuleuse, s’étend ainsi dans le ciel sur une taille apparente de 1°, soit le double de la pleine Lune.
L’amas lui-même s’est formé très récemment, puisque celui-ci est âgé tout au plus de 1,5 millions d’années… un battement de cil à l’échelle de temps cosmique !

Under a frigid but very clear sky last night I tried out a new filter and was able to combine the resulting data with some previous images to produce this composite of the star-forming region known as IC 410, the larger cloud at upper left, along with the smaller IC 417 to the lower right. (For the astronomy purists, this is rotated relative to the usual north-up orientation, but I thought it looked more interesting this way (and there's no "up" in space anyway).
This rendering is a lot like many of the images from the Hubble Telescope that combine the light of the three elements sulfur, hydrogen, and oxygen into the colors red, green and blue respectively.

My first attempt at the Triangulum Galaxy, a spiral galaxy located 2.73 million light-years from Earth in the constellation Triangulum. It is the third-largest member of the Local Group of galaxies, behind the Milky Way and the Andromeda Galaxy. It is one of the most distant permanent objects that can be viewed with the naked eye but only in very low light polluted areas. This is right at the limit of what my scope can presently achieve so the detail is lacking. That said I had limited data here having lost half the night's effort due to a tree invading the shots.

Stacked in DSS, edited in PS and finished in LR
This is with my home setup -- Celestron Edge HD 925 with ZWO ASI120MM camera, 3x Barlow, and Optolong RGB filters. I wanted to see if I could keep Europa and its shadow looking decent while shooting with a mono camera. To do this, I limited the RGB SER files to 12 seconds and took each set in under a minute. After stacking in AutoStakkert and doing some sharpening in PixInsight, I used WinJUPOS to derotate the frames so I could check the resulting RGB images for color distortions around the moon or its shadow. Seeing that they weren't discernible, I stacked and derotated six RGB images from 0429 to 0440 UT in WinJUPOS and tweaked the result a little in PixInsight and Photoshop.
Europa is visible just below and a bit to the right of its shadow. I couldn't get any detail on it. Seeing varied from mediocre to good. This is from my backyard in Long Beach, CA.
This beautiful nebula is called Helix nebula (NGC 7293) or Eye of God and sometimes called Eye of Sauron. Its the closest planetary nebula to the Earth about 450 light years in constellation of Aquarius. It is a dying star that blown out its outer shell. The remanent star in the middle of the nebula is a white dwarf that reaching its end of life and nearly finished the nuclear fuel. The colors of this object is due to presence of the very hot white dwarf that energize the central part of the nebula in green from the ionized Oxygen. The outer part is Hydrogen gas glows in Red. Just imagine that, those gases are expanding at rate of 40 km per second.

My first reasonable tricolour image using three narrowband filters from Optolong to create the colour. I assigned the Hydrogen Alpha frequency to Red, the Oxygen3 frequency to Green and the Sulphur frequency to Blue.
Total exposure for this image is 15 hours in total across the three filters.
