Dust Cloud 183 (top left) was first cataloged by Dr. Lynds in 1962 (1) and has recently been calculated to be 105 parsecs away (2). It is part of a complex of cold, dense, and starless dust and molecular clouds which also includes LDN 134 (lower right).
I wanted to frame the photo in a different way and found that it looked quite dramatic flipped into portrait mode. Frames were taken south of Grafton in a Bortle 4 location by Lake Ontario.

Descrição:
A Nebulosa de Eta Carinae é uma das jóias do céu do
hemisfério Sul. São muitos as zonas interessantes a se destacar: Keyhole, bright-rimmed globules, dark globules, Dust Pillars, Star cluster Trumpler 14 e Trumpler 16, Mystical Mountain e os Stellar Jets. É uma das maiores nebulosas difusas do céu e cerca de quatro vezes maior que a Grande Nebulosa de Orion. Está a cerca de 7500 anos-luz da via láctea. A região central da imagem nos brinda com brilhantes filamentos bem como nuvens escuras de poeira cósmica.
There are a lot of firsts for me in this image. First deep sky image from a dark sky (SQM 21.3 on this night), first image with new camera (SBIG STF-8300C), first time automating entire imaging run (via ACP), and first time combining images from multiple nights. It's also the first time I've done the majority of processing in PixInsight. So much to learn in this hobby!
Full acquisition and equipment details here.

Really dense region on dark nebulae.
Imagen taken with a "simple" equipement, an inexpensive mount, a camera lens and ASI1600 camera.
The key point to that picture is this high f.3 used and a really dark site location.
And of course, also fine processing is needed to show all that beauty
I will continue with this setup for a while, I am thinking of changing the mount to a new one with harmonic drives.... will see.

CTB-1 aka The Garlic Nebula
IG: www.instagram.com/p/CTp1xyVhXIN/
AB: www.astrobin.com/nbsqqv/B/
This image was captured from my backyard observatory (total integration time: 25 hours)
CTB 1 is a supernova remnant (SNR) in the constellation Cassiopeia. This particular SNR was catalogued by George Abell as a planetary nebula in his now well-known catalogue as Abel 85 but it was suggested by van den Bergh in 1960 and confirmed by Willis & Dickel in 1971 to be, in fact, not a planetary nebula but rather a galactic SNR. CTB 1 is approximately 9784 light years away and physically spans another 98 light years in diameter while it is dated to be approximately 10,000 years old.
A recent study by Schinzel et al. reports that a pulsar was running away from CTB-1. The pulsar was likely born from the very same supernova explosion that produced the remnant. Supernova explosions don’t have a perfect symmetry, and the pulsar likely received a natal kick that sent it tearing away from its birthplace at speeds exceeding 1000 km/s, causing it to eventually overtake the expanding shell of gas and dust.
(link to the study: iopscience.iop.org/article/10.3847/2041-8213/ab18f7)
The area top left of CTB1 has been confirmed as a shell rupture. This is likely to be the result of the supernova remnant's interaction with a nearby cavity of neutral hydrogen gas.

This is a re-process of my original RGB photo from May 2024. An additional 1 hour of luminance subframes was added to the original image stack. Thsi helped to bring out the details of the molecular cloud and trails of dust.
Additional technical details can be seen at my Astrobin page:
NGC 4631 (also known as the Whale Galaxy or Caldwell 32) is a barred spiral galaxy located at 30 millions light year away in the constellation Canes Venatici.
More than 17 hours of integration on a new try to show all possible details with my equipment.
It's the last target before the COVID situation and before to stop all remote activities on the observatory, because just in case...

The Elephant's Trunk Nebula is a concentration of interstellar gas and dust within the much larger ionized gas region IC 1396 located in the constellation Cepheus about 2,400 light years away from Earth.
On this wide field image the, elephant trunk is the darker region in the lower third of the image with a lighter rim around it’s dark form. The lighter rim is the surface of the dense cloud that is being illuminated and ionised by a very bright, massive star HD 206267
Taken over three nights at the observatory in Los Coloraos, Gorafe, Spain.

The Elephant's Trunk nebula is a region of ionized gasses located in the constellation Cepheus at a distance of 2,400 light-years from Earth. Of interest in this area is the population of very young newborn stars, whose intense stellar winds are excavating the interior of the nebula. Dark wisps of dust hide the cocoon of forming stars, called "globules", which will be blown away when the star ignites.
Captured recently in Narrowband and Broadband using a QHY600 60 Megapixel Full Frame Monochrome CMOS camera mounted on a Takahashi 130 FSQ, courtesy of QHYCCD.
This setup is available immediately for people wanting to subscribe to Grand Mesa Observatory's system 1.

In this Hubble Palette version (SHO) the H-Alpha is mapped to green channel, SII is mapped to red channel and OIII is mapped to the blue channel. The raw data was preprocessed using Pixinsight, the stars were removed using a tool called "Starnet" and the stars were later replaced during Post Processing in Photoshop CC with the more naturally colored stars from the RGB data.
I was so delighted with the result of the starless image I decided to post a starless image as well as the image with the RGB stars.
Captured bin 2x2 over 5 nights between March and July 2021 for a total acquisition time of 13.1 hours.

The starting point for this image is the NASA APOD that I took in cooperation with Federico Pelliccia at the end of October 2013 (apod.nasa.gov/apod/ap131029.html). In this last week I had a chance to rework on this object due to bad weather conditions. I reviewed the colors, applied some customized denoise techniques and merged my IC434 (www.astrobin.com/74396) image here in this one.

Really beautiful object catalogued as 881 on the Lynds' Catalogue of Dark Nebulae.
It's one of the jewels that you could find on gamma Cygni nebula, on SADR region of Cygnus, one of my favorites regions of the sky.
"A dark nebula or absorption nebula is a type of interstellar cloud that is so dense that it obscures the visible wavelengths of light from objects behind it, such as background stars and emission or reflection nebulae. The extinction of the light is caused by interstellar dust grains located in the coldest, densest parts of larger molecular clouds." (wiki)
It was necessary to integrate more than 70 hours to show all faint and nice details on the estructure.
Here was captured using the more natural palette, please also check my HSO palette on this link:

I recently assisted my good friend, GMO volunteer and astro-photographer Kim Quick in post processing his data on Omega Centauri, the largest and most massive Globular Cluster in our Milky Way in the constellation Centaurus.
I still remember viewing this "one of the most beautiful objects in the night sky" as a child growing up in Australia.
Kim captured this data in LRGB over 3 nights in May 2020 using iTelescope's T32 at Siding Springs, NSW Australia.

The Humunculus nebula is a very difficult object to be photographed by amateur astrophotographers. With a combination of very short exposures, I was able to partially solve the nebula even while photographing with a telescope with little aperture. I hope you like the result, in the coming days I will update this capture with short exposures in RGB to be able to solve the colors of this beautiful nebula.

Iteration on the Sharpless catalogue of faint nebulae.
It's not a common object, and here is the close up. Very faint and difficult. I am really proud of it :D
Sh2-170 is an emission nebula in Cassiopeia at around 7500 light years away.
The bright star at the centre of the nebula is ionising the surrounding hydrogen gas, causing the nebula to glow.
This nebula is about 2/3 the diameter of the full moon.

Bon ciel.
La nébuleuse en émission de la Tête de dauphin Sh2-308 est située à 5 200 années-lumière de la Terre (cf. Robert Nemiroff & Jerry Bonnell) dans la constellation du Grand Chien (Canis Major). Cette bulle cosmique de 60 années-lumière de diamètre est sculptée par les vents stellaires intenses d'une étoile Wolf-Rayet extrêmement rare (type spectral WO) en son cœur, l'un des objets stellaires les plus massifs et les plus éphémères de la Voie lactée. Cette nébuleuse se serait formée il y a environ 70 000 ans par l'éjection des couches extérieures de son étoile binaire centrale principale EZ Canis Majoris-WR6 (étoile massive en fin de vie, expulsant sa matière à grande vitesse avant de probablement s'effondrer en supernova).
Les étoiles Wolf-Rayet sont connues pour éjecter de la matière à des vitesses dépassant 1 700 km/s et la nébuleuse Sh2-308 illustre ici cette violence avec une précision remarquable. Ses filaments complexes brillent principalement en émissions d'oxygène doublement ionisé (rendu ici en bleu) et d'hydrogène alpha (souvent cartographié en rouge). Ces éléments tracent les ondes de choc, là où les vents supersoniques de l'étoile entrent en collision avec de la matière plus lente expulsée lors des phases évolutives antérieures (cf. app.astrobin.com, merci Simbiosisgroup pour la photo).
Pour situer la nébuleuse de la Tête du dauphin Sh2-308 dans la constellation du Grand Chien (Canis Major) :

Here is my latest Bi-Color version of NGC2264 - The Cone Nebula taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY);
I have never done it before and I am very happy of this result.
Unfortunately the seeing was not so good, and this is the reason why the stars are not so much point-like.
I hope you like it and clear skies!

The Cat's Eye Nebula also known as NGC 6543 is a planetary nebula in the northern constellation of Draco, discovered by William Herschel in 1786. The bright planetary nebula is the very small central core within the large surrounding outer halo. The difference in brightness between the core and the outer halo makes this a very challenging target to process. Outside the bright inner portion of the nebula, there are a series of concentric rings, thought to have been ejected before the formation of the planetary nebula.

In astronomy, the Pleiades (/ˈplaɪ.ədiːz/ or /ˈpliː.ədiːz/), or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The celestial entity has several meanings in different cultures and traditions.
The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula.[7] Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.[8]

Exercício (primeira tentativa) ontem com NGC 2997 (Galáxia Espiral na Constelação de Antlia). Foram empilhados 24 frames de 300 segundos, totalizando 2 horas de exposição. Como é um objeto sem grande brilho aparente (visto da Terra), seria interesante mais tempo de exposição para melhorar o registro. O processamento foi bastante difícil. Aos poucos vamos avançando.
O NGC 2997 é uma galáxia espiral não barrada, localizada a cerca de 40 milhões de anos-luz de distância na constelação Antlia. NGC 2997 contém centenas de bilhões de estrelas e acredita-se que tenha uma massa de cerca de 100 bilhões de vezes a do nosso Sol, mas provavelmente é menos massiva do que a nossa Via Láctea. A galáxia está se afastando de nós a cerca de 1085 quilômetros por segundo. Fonte: annesastronomynews.com/

Exercise (first attempt) yesterday with NGC 2997 (Spiral Galaxy in the Constellation of Antlia). 24 frames of 300 seconds were stacked, totaling 2 hours of exposure. As it is an object without great apparent brightness (seen from Earth), it would be interesting to have more exposure time to improve the record. Processing was quite difficult. Gradually we will advancing.
NGC 2997 is a unbarred spiral galaxy, located about 40 million light-years away in the southern constellation Antlia (the Air pump). NGC 2997 contains hundreds of billions of stars and is thought to have a mass of about 100 billion times that of our Sun, but is probably less massive than our own Milky Way Galaxy. The galaxy is speeding away from us at about 1085 kilometers per second. Source: annesastronomynews.com/

Polaris is a star in the northern circumpolar constellation of Ursa Minor and is commonly called the North Star or Pole Star.
With an apparent magnitude of around 2, it is the brightest star in the constellation and is readily visible to the naked eye at night.
The position of the star lies less than 1° away from the north celestial pole, making it the current northern pole star.
The stable position of the star in the Northern Sky makes it useful for astrophotographer in the Northern hemisphere to align our telescopes with the central axis of the Earth. [Wiki]
Imaged over 11 nights in June and July 2024 while waiting for my main target to reach altitude.
I have always wanted to capture the IFN (Integrated Flux Nebula) around our pole star in the Northern hemisphere.
I thought that while I am waiting for my main target to rise in altitude, just sitting on Polaris would be a cool idea.
The main problem is guiding your telescope at the pole. In the end none of the frames were guided, Plate solving was interesting too. I attempted to centre the star but the mount would never end up plate solved and locked on. The solution was to place Polaris off centre. The result was that I obtained a better view of the IFN surrounding the star.
735 x 2 minute images were originally taken without a filter and reduced down to the best 349. This left me with over 11 hours of the best frames to process.
I am very pleased with my first attempt. I must look at either making a mosaic or using a wider FOV telescope to feature more of the surrounding space dust.

This is my last picture taken from the AstroAtlas Observatory situated in Noventa di Piave (ITALY).
This is M33 in H-aLRGB. I have been trying to photograph many times... It seems to be easy but, in my opinion, it is challenging to process.
I am impressed from the hydrogen present in this region.
I hope you like it and clear skies!

This picture is the result of an integration of 6 hours on RGB and another 54 hours in narrow band, using a focal length of 530mm and aperture f3.3
It was a long project in terms of acquisition period, five months of capturing frames from September 2022 to January 2023, only on nights with no moon.
The elaboration was a little bit more complex as usual due the high number of stars on the frame.
I really like how this Epsilon shows all fine details and structures on the nebulae, and how PK116+00.1 is properly defined.
CTB 1 is a supernova remnant located in the Milky Way galaxy.
It is thought to be the remnants of a massive star that underwent a supernova explosion, expelling its outer layers into the interstellar medium and leaving behind a compact object such as a neutron star or a black hole.Supernova remnants are important because they help us to understand the evolution of stars and the processes involved in supernovae.
They also release large amounts of matter and energy into the interstellar medium, which can have a significant impact on their surroundings.
CTB 1 was discovered in the late 1970s and has been the subject of numerous studies since then. These studies have helped to improve our understanding of the structure, dynamics, and evolution of supernova remnants, as well as the properties of the supernova explosions themselves.
It is believed that CTB 1 is relatively young, with an estimated age of only a few thousand years. This makes it an important object for studying the early stages of the evolution of supernova remnants, and for understanding the processes involved in their formation and evolution.
