"Oceanic Cosmos": The Dolphin Head Nebula in Aquatic Hues.

My latest acquisition, not sure how I feel about this yet, I may choose to add more data later.
All my socials here: https://linktr.ee/deepskyjourney


ABOUT THE ACQUISITION


Despite being observed from a Bortle 6 location in my Brisbane backyard, the nebula's charm is vividly captured. The observation challenges however were significant due to the month's full moon and suboptimal FWHM readings between 2.76" and 3.46" due to high clouds. Because of this, I was not able to highlight the presence of a round bubble at the bottom edge of the nebula (planetary nebula candidate PNG 234.9-09.7). You can *just* slightly see its presence if you know what you're looking for.


Nonetheless, some of the nebula's details were seized at a modest focal length of 250mm using a RedCat 51 telescope. The image is further embellished by the bright presence of the red-orange supergiant O¹ Canis Majoris and the stellar ensemble of the open cluster Collinder 121, adding depth to the celestial scene captured from this urban setting.


ABOUT THE WIDEVIEW


This astrophotography endeavor captures a broader celestial landscape beyond the Dolphin Nebula, spanning from -22º to -26º in declination and extending from 6h50min to 7h in right ascension. Centered at RA 06h54m14s.93 and DEC -23°51′59″.9, the image offers a wide field of view of approximately 3.007 degrees, with a pixel scale of 3.879 arcsec/pixel and oriented at -89.219 degrees. This wideview includes not only SH2-308 but also other significant astronomical features such as SH2-303 and the planetary nebulae candidates PK233-10.1 and PK236-10.1. The detailed capture of this expansive celestial region, despite the challenges posed by less-than-ideal observing conditions, showcases a rich tapestry of stellar and nebular phenomena, adding a broader context to the captivating scene centered on the Dolphin Nebula.


ABOUT THE NEBULA


The Dolphin Nebula, also known as SH2-308, is a captivating emission nebula formed by the intense ultraviolet radiation from the Wolf-Rayet star WR6, also known as EZ Canis Majoris. This star, a luminous beacon with over 600,000 times the sun's brightness yet only 26 times its mass, plays a pivotal role in the nebula's striking appearance. Predominantly illuminated by OIII emissions, the nebula's intricate structures, reminiscent of a dolphin's brain, are also accentuated in Ha emissions.

Comet 12P/Pons-Brooks

Imaged at UT 2024-03-02 02:23. This comet is now showing a very complex ion tail, as well as interesting changes in its coma. I'm not sure what's creating the double coma; there doesn't appear to be any dust, so I assume most of what we're seeing is gas and ice particles. Perhaps a recent eruption of ice is scattering enough sunlight that the green CN/C₂ glow of the larger, older coma is washed out near the nucleus.

The Monkey Head Nebula is a star-forming region located 6,400 lightyears away in the Orion constellation. NGC 2174, to give it is formal name, is a place where new stars are being born at a fierce and rapid rate, and these newly born stars emit powerful streams of charged particles known as stellar winds that blow the gas and dust away, removing the ingredients necessary for future stars to be born. Dark dust streams among the glowing cosmic cloud to give the nebula its ape-like appearance. Indeed, it is one of many nebulae that look like animals

M31 - the kilohour project and the quest for Oiii by William Ostling, on Flickr

After half a year of work, the Deep Sky Collective is happy to present its latest project - a kilo hour on M31. Not only does this image set new boundaries of what’s possible with collaborative imaging, its release also marks the DSC’s anniversary project! Being launched the 13rd February last year, we never thought we could achieve what we did so far - huge thanks to everyone involved in the DSC and for keeping on believing in what we do.

Behind the scenes we’re working on in-depth tutorials for everyone to access - our hope is that other ambitious photographers out there can make use of these tutorials and get started in collaborative imaging themselves - helping us get started in a new era of collaborative imaging. Expect the first tutorials to be released in 1-2 months.


The Andromeda galaxy, also known as Messier 31, is a galaxy in the constellation Andromeda. It lies at a distance of roughly 2.5 million lightyears, making it the closest (non-satellite) galaxy to our Milky Way. M31 is a big galaxy, spanning some 200.000 ly in diameter whereas our own galaxy “only” spans some 100.000 ly in diameter. Furthermore, M31 is heading towards us at 400.000 km/h which will result in a collision that is predicted to happen in 4.5 billion years - after this collision the two galaxies will merge, forming an even bigger one, set to be named Milkdromeda.
M31 is one of the most popular targets for amateur astrophotographers, as it’s very big in the night sky and very bright, even being visible to the naked eye when observing from dark skies.
In addition to being a fun target for new astrophotographers to go after, M31 also has proven to be worth pursuing for more advanced photographers. This is due to the faint features such as the Halo surrounding M31, the dim Ha background, or the Oiii outbursts, pillar and arc just southeast of the galaxy which was only discovered in 2022 by Drechsler, M. ,Strottner , X. and Sainty Y.
This variety of interesting features made M31 the perfect target for the next Deep Sky Collective project. Having started this target in August, it also marks the longest project we ever had up until now. For this colossal effort, 22 people worked together- 1 Editor, 3 co-editors, 17 photographers and myself, coordinating the project.
Note that the final version is a blend of Uri's and Steeve's edit.

In our final image of M31 you see here, all of these amazing attributes of M31 can be found - a staggering 488h of Oiii integration was gathered to go as deep as no one managed before. For the Ha emissions in the background, a total of 314h of Ha integration were gathered to provide the deepest look yet. Besides the now traditional H-alpha and Oxygen III for M31, we also decided to do something unusual and get Sii - In the end we ended up with a total of 169h. The goal behind this was to 1) photograph the extragalactic nebulae in M31 in SHO and 2) check for any Sii in the arc - for our findings, refer to interesting features in our image.
Finally, by Mid January, and after rejecting bad frames we ended up with a record breaking 1056h (or 1 ½ month) of integration over the LRGBHaOiiiSii channels, which marks the longest integration time ever on a single panel for any astrophoto. While the results might diminish at these crazy integration times, the effort more than paid off.

Before we jump into the details of the picture, a big thank you to everyone who played a part in this project. This endeavour is a manifesto to the incredible possibilities that collaborative imaging brings to the amateur community. Working together with all of you has been a real pleasure!

Special thanks to:
Carl, who put in a tremendous effort - not only did he stack a staggering 5600+ files, but he also developed a whole new stacking workflow with starting help from Charlie, which vastly improves the image quality and allows for automation. Huge thanks for his immense commitment to the project - none of this would be possible without him! Eager to help the community get started with collaborative imaging, he also released the DeepSkyCollective processing suite on PixInsight, containing the newly developed tools that were used for this project. I strongly recommend checking it out on <a href="https://elveteek.ch/pixinsight" rel="noreferrer nofollow">elveteek.ch/pixinsight</a>
William, Uri and Steeve, for their impressive edits. A lot of time and skill goes into these edits, so big thanks! By having multiple edits we could cross check that all details are real.
Big thank you to Charlie who came up with the new stacking workflow which was later adapted by Carl.
Sendhil and Tarun, who gave us their excellent Bortle 1/3 data that was kept available for MSGR
Justin, who provided us with close-up data of the core. As our big stack's core was fried his data was used to blend in and fix the core which was a huge improvement

M 38 and NGC 1907 in HaRGB


(Thumb only)

>>>High Resolution: https://astrophoto-hannover.de/download ... s_Horn.jpg

M 38 is a 220 million-year-old open star cluster in Auriga, also known as the "Starfish Cluster." In the night sky, the open cluster NGC 1907 (500 million years old) appears to be in close proximity, but in reality, both objects are far apart: M 38 is approximately 3,480 light-years away from Earth, and NGC 1907 is about 5,100 light-years away.
Both star clusters seem to float in a sea of H-alpha clouds. However, these belong to the Taurus molecular cloud, which, at a distance of "only" about 430 light-years, is the nearest star-forming region to Earth.
I wanted to show the clusters in a different context. For this, I fortunately was able to combine 5.5 hours of H-alpha data from this area, which I had captured in January for another project, with the RGB image. I hope you like it!

The Portrait of the Monkey
This time it is a larger portrait, where we can see an area of hydrogen present in the shape of an arch, which looks like the neck and bust of the portrait.
That's why I wanted to title the photograph "The Portrait of the Monkey."
Very similar to the portraits that are minted on coins.
So, what is significant about this image is that it has much more strength in the hydrogen areas that interact with the gas present, forming new stars.
The photograph was taken from the skies of Áger, (Spain). I have my observatory there. I captured it during the months of January and February 2024.
For the image I made a total of 19h 45m of exposure, on the Hubble palette, using the 150 refractor telescope and sub exposures of 5 minutes in the Ha, SII and OIII filters.

Cities of stars and a few galaxies - M53 & NGC5053

I love Globular Clusters, I have heard them described as “Ancient stellar cities” - I think that’s a brilliant way to think of them.
Open and globular clusters are not given enough ‘Press’ in my opinion – I plan to image more of them, weather permitting
There are hundreds of galaxies in the view too – so we have Cities of stars with Megacities of galaxies in the background.

I'am Simone Curzi from Italy.
Sh2-308 is the minor project of SHARA N.8, and this is my personal interpretation.
Minor only in the number of poses, in fact it has been a long time that I have hoped to get my hands on this deep-sky object that has always fascinated me.
Sh2-308, also designated as Sharpless 308, RCW 11, or LBN 1052, and commonly known as the Dolphin-Head Nebula, is an H II region located near the center of the constellation Canis Major, composed of ionised hydrogen. It is about 8 degrees south of Sirius, the brightest star in the night sky.
Thanks to Bill Blanshan's formulas for the normalization of narrowband channels and the transfer of RGB stars to NB, I obtained a result that leaves me very satisfied. Hoping to be able to return one day to this object with a greater number of poses, I greet you and wish you clear skies

The Great AR3590 by FabricioBS, no Flickr

Immediately following the largest flare of the current solar cycle, I captured a close-up view of the extremely active region AR3590 as soon as the clouds cleared in Rio de Janeiro/RJ, Brazil. This detailed view showcases the largest sunspot, which is twice the size of Earth, along with numerous peripheral ones, flares, and filaments. To achieve this, I took 1,416 exposures across four different and superimposed frames. I then processed the top 5% of these exposures, combined the frames and artificially colored them in yellow-orange hues. The original shots were monochrome to allow for a higher resolution image, captured in the deep-red hydrogen-alpha spectrum of visible light.

Comet 12P/Pons-Brooks

Copyright: Julien Looten




Comet 12P/Pons-Brooks, first discovered in 1812 by astronomer Jean-Louis Pons, has captivated the interest of celestial observers ever since. With an orbital period of just under 71 years, this periodic comet was rediscovered in 1883 by William Robert Brooks, confirming its regular trajectory around the Sun.
With a diameter of around twenty kilometers, this comet is a small star made up of ice and dust, typical of objects in this class. As it approaches the Sun, it becomes increasingly visible, releasing tails of gas and dust.
Comet 12P/Pons-Brooks is what astronomers call a cryovolcanic comet. On its surface, geysers eject liquid hydrocarbons and gases under the effect of solar heat. Since December 2023, this comet has already seen at least six significant eruptions, testifying to its dynamic activity.
The comet is currently heading rapidly towards the Sun and Earth. Visible through binoculars for the past few days, its brilliance should continue to intensify over the coming weeks! It's time to take a look at the sky!
This photograph was taken in Etretat (France), despite a heavy haze of fine particles that hampered observation. Approx. one hour exposure - Askar Fra 400mm on StarAdventurer GTI - Canon 6d II. 06/03/2024
