NGC 6946 - Fireworks Galaxy
Full version : https://cdn.astrobin.com/thumbs/4SrfNLy ... TZ0INm.png

Located in the constellation of Cepheus, NGC 6946 is a Sc-type spiral galaxy seen almost head-on, of modest size: its diameter is around 40,000 light-years (about a third the size of the Milky Way) and it contains half as many stars as our own galaxy.

Despite its small size, this galaxy is very active in star formation, as demonstrated by the presence of large HII zones in the spiral arms.

Another sign of this sustained stellar activity is the fact that no fewer than 10 supernovae have been observed in the space of a century (between 1917 and 2017), a rate far higher than that of most spiral galaxies. By comparison, no supernova has been observed in the Milky Way since 1604, even though our galaxy contains more than twice as many stars. Because of this particularly high level of activity, NGC 6946 is nicknamed the “fireworks galaxy”.

Although relatively close to the Milky Way on a cosmic scale (22 million light-years), this galaxy has long been overlooked by observers, not least because of its peculiar position close to the galactic plane, where the dust-rich interstellar medium absorbs much of the light emanating from it.

ImageComet 2023 A3 (Tsuchinshan-Atlas) Over Siding Spring Observatory by Blake Estes, on Flickr

The wind and cold were brutal this morning, at Siding Spring Observatory, but what a sight it was! There was also some beautiful airglow that was visible into the beginning of twilight. The comet is getting lower each morning in the southern hemisphere, but it is still putting on a beautiful pre-dawn show.

Comet C/2023 A3 Tsuchinshan-ATLAS from Emilia

ImageC/2023 A3 Tsuchinshan-ATLAS - Semptember 29th 2024 by Alessandro Carrozzi, su Flickr

Comet C/2023 A3 Tsuchinshan-ATLAS taken on the morning of September 29, 2024.
Currently nearing perihelion—the closest point in its orbit to the Sun—the comet has significantly brightened, making it visible just before sunrise. However, viewing conditions from our northern latitudes are less than ideal: the comet is immersed in the pre-dawn glow and rises only a few degrees above the horizon before the Sun, making it primarily a photographic subject rather than one easily observed with the naked eye.
This image captures the comet just above the hills of Bologna, with the Basilica of San Luca recognizable in the distance. Closer to the foreground are the areas of Maranello and Fiorano, featuring the Beata Vergine del Castello sanctuary.
Technical details: The image was taken using a Canon EOS 6D paired with a Nikkor 180mm f/2.8 lens on a SkyWatcher Star Adventurer. It is a composite of three different images. The comet itself is the result of integrating 17 shots (each 1 second at f/4, ISO 3200 and 1600), blended with the sky from one of the subframes to keep the clouds stationary. The landscape was created using an HDR composition of exposures ranging from 1/4 second to 4 seconds at f/5.6, ISO 400.
Despite the complexity of the processing, care was taken to preserve the relative positions of all objects in the scene

Captured in the early hours of September 30, 2024, this image showcases the magnificent Comet A3 Tsuchinshan-ATLAS as seen from Beachmere, Queensland. The comet, which last visited our solar system over 80,000 years ago, is currently gracing our skies with its bright tail and vivid colours.

Using my DSLR and Tamron lens, I was able to capture this stunning view just before dawn, highlighting the comet’s intricate details against the serene backdrop of the pre-dawn sky. This rare celestial event has been a thrilling experience to photograph and share with the astronomy community.

The only opportunity in the south of Chile to be able to portray this beautiful star, it was worth the sacrifice and the anxious wait, now we face a storm that does not give way to respite.

When I lost all hope of being able to see it, it appears on the mountain in the town of Lago Chapo, in the south of Chile, first I see its beautiful tail that is little by little rising, and when it appears it gives the sensation of kissing the mountain.

Return to the Cave One of my first astro images when I first bought my Hyperstar lens was this dark and mysterious cave in Space. I have always loved it and was pleased to see how striking the natural colours were ( no narrowband filters were used) How fun to return to the cave with my deep rig at t 1960 mm

This red space cave is roughly 3,000 light-years away and lying in the plane of our Milky Way galaxy, the Cave Nebula is an emission formed of gases that emit their own light. The bright arc that forms the mouth of the cave is an active birthplace for stars, known as an H II region, where hot clouds of atomic hydrogen have become ionized. The natural colour allows us to see the wispy blue reflection nebula as well. These are dusty regions illuminated in blue by the young stars
Though covering a span of roughly 40 light-years across, Caldwell 9 is a diffuse and low-contrast object, so it can still be difficult to find in the sky. Its first known notation, in fact, was not until 1959 after astronomer Stewart Sharpless captured it on photographic plates and included it as the 155th object in his second catalog of H II regions, giving Caldwell 9 its alternate catalog name, Sh2-155.

MWP1 Methuselah Nebula in Cygnus  imaged with Epsilon 160 and Player One Poseidon mono CMOS remotely from Spain.  Exposure times were 200x 180s in O3 100x 180s in Ha and 30x 60s in each RGB filters.
Not your usual Planetary Nebula with is very unusual structure. Quite a rarefied object in RGB but add some H-alpha and O3 and it really shows itself off. The O3 really transforms it, I particularly love the striated structure in the O3 columns.

On September 30, 2024, I captured an image of Comet C/2023 A3 (Tsuchinshan–ATLAS) from Beachmere, QLD. The comet's tail extended more than 20 degrees across the sky, equivalent to six full moons. This rare event offered an ideal opportunity to photograph the tail’s structure, which was composed primarily of dust and ionized gases illuminated by sunlight. The calm tidal waters of Beachmere provided an additional element, reflecting the tail’s length and brightness on the surface. The image showcases the comet’s position relative to Earth.

I set out to explore NGC 7331, Stephen's Quintet and its surrounding region. During this journey of galactic exploration, I have come across a few surprises. One was the inclusion of this beautiful galaxy group in the top left corner of the image, with a prominent NGC 7345 and 7342 and a group of galaxies below them.

But the biggest surprise was finding a faint but defined Hydrogen alpha emission signal that appears as a river flowing from the bottom right of the image to the top of the image crossing Stephan's quintet and NGC 7331.

This was captured from Starfront Remote Observatories using my following equipment that is hosted there:

Unlocking the Helix Nebula: A Journey Through Time and Tech

After capturing the Pillars of Creation in late July with my 90's scope - the Celestron Ultima 9-1/4, I decided to turn my attention to the Helix Nebula (NGC 7293). This nebula is well-known for its complexity, and I quickly realized how challenging it would be to capture all of its intricate details at the native 2350mm focal length and slow f/10, as well as my bortle 6 skies. Still, I wanted to see what could be done by combining this classic equipment with modern technology.

The Challenge
The Helix Nebula’s delicate structure took a lot of effort to bring out. Using the ASI2600MM-Pro camera and Antlia 3nm narrowband filters, I spent more time than I'd like to admit refining the data to get the best result I could. It was tough, but I’m happy with how it turned out, showing that even older gear can still perform well with today’s tools.

Classic Meets Modern
Although the Helix Nebula has been photographed many times, this image is special to me because it highlights what’s possible when you combine equipment from different eras. It’s proof that with patience and persistence, classic telescopes can still capture some amazing views of the cosmos.

ImageTsuchinshan Atlas comet over the pyramids by Wael Omar, on Flickr



I planned for this images from 10 days ago, during this period i need to overcome several problems to make this image come true.:
1- I was searching for a high place to have a clear view of the 3 Egyptian pyramids and in same time to include the rise of the crescent moon and Tsuchinshan comet. Finding such a place in a very crowded area like Giza is very difficult as there will b
e always a residential building blocking the view so i continued in searching and exert too much efforts until I finally found that high place, it was about 2.7 km in the west of pyramids and by photopills app i confirmed that i ll have both the comet and the moon in frame from that place.
2- That was a bortle 9 sky and even after imaging the stacking apps failed to find the comet and make the stacking so i had to manually stacking around 25 subs for each layer to reveal the details of the comet. This manual stacking was a pain and consumed over 9 hours to succeed in stacking these images.

Gears:

Sony A7III astromodified Ha

Sigma art 85 mm DG F1. 4

Settings:

· Manual Stackeing of 25 subs for each comet layer, iso 800, 0.8 second , F2.8

All images are from same place same gears same night.


Location: Giza, EGYPT.

C/2023 A3 (Tsuchinshan-ATLAS) and ion tail from Peru 10/02/2024

The Andes mountains in Peru reach up to 6800 meters above sea level, that makes it very difficult from the cities to find places with low horizons (especially to the east) that allow observing and photographing comets when they are at their best. To get this image we had to move to the top of a mountain at 4500 meters above sea level, in front of a glacier that rises to almost 6 thousand meters called Huaytapallana. This is the only way to get a place with a really low horizon that allows us to see the comet a few more minutes before the brightness of dawn takes over.


The intense cold with temperatures below 0 degrees and the lack of oxygen were not a bother from the moment the clouds began to move and allowed us to contemplate this superb celestial spectacle.


The bright core was visible even through the light clouds. The tail was very easily visible and extended several degrees in the direction of Sirius; it was so noticeable to the naked eye that even a cell phone camera could capture a clear image of this fuzzy object. This is undoubtedly the most spectacular comet that I have had the opportunity to see with the naked eye and without the aid of optical instruments.


What surprised me the most when I started to process the photographs was to notice a thin, irregular tail with a slight bluish tint. Apparently this is the ion tail. I saw this faint tail a few days ago in a photograph by astrophotographer Yuri Beletsky. It was sensational to discover that I had also captured it.


This image is the result of stacking 5 photos of 25 seconds with the Sony A7III camera together with a 135mm f2 Samyang lens.

The processing was done with Photoshop and Pixinsight.
