Echoes of Eternity: Memnon and the Comet (Comet C/2023 A3 Graces the Colossi of Memnon)

The Colossi of Memnon stand tall and majestic, like silent guardians that have witnessed the rise and fall of empires and civilizations. Their stony gaze, fixed across thousands of years, holds countless stories of the ancient past.

On this particular night, the night sky is adorned with a unique spectacle that adds a special magic to the atmosphere. Comet C/2023 A3 (Tsuchinshan-ATLAS) steals the show, painting a magnificent work of art across the vibrant space. Its light dances around one of the statues, erected in 1350 BC for the King Amenhotep III, as if reviving the spirit of the past and recalling the grandeur of the Pharaohs.

This comet, which completes its cosmic journey once every 80,000 years, has not been witnessed even by the oldest civilizations that inhabited this land. It is a rare guest from the depths of time, reminding us of the insignificance of our existence in the face of the vastness and eternity of the universe.

VDB152 ,sometimes called the "wolf's cave" nebula in Cepheus is my first image after re-installing my dual telescope rig on a lower pier to make it more resilient against wind gusts. Sounds easy , right not really as everything needed to be re-aligned and calibrated.
We also took the opportunity to drift align the mount to get a true mount alignment rather than a guide scope. I have to thank John Adler for his assistance in this.
When deciding on a first image to take I thought about whether to go for a Planetary nebula, maybe Supernova remnant, Dark nebula, Reflection nebula?

In this image all these are present! Cepheus is the most amazing region in the sky.
VDB 152 is the bright bluish area in the middle of the image. To me it looks like a birds beak not a wolfs cave. The red tendrils are from an ancient supernova remnant SNR 110.3+11, and to the lower right is the planetary nebula DeHt5 , the dusty dark nebula in the center is LDN1217

M45 OSC & an NBZ filter

M45 The Pleiades. What a wonderful part of the sky, when ever I see it rising in the East I know that the winter of on its way. It still amazes me what can be done with a OSC camera and dual band filters.
Imaged remotely from Spain in One Shot Colour and Ha/O3 Dual band IDAS NBZ UHS filter ultra wide 105 Sigma and the Player One Poseidon-C Pro. Exposure times were 260s x 60s in OSC and 60x 180s in Ha/O3.

This is something I have been meaning to do for ages and combine some H-alpha with RGB. There were always signs of there being enough in the field to make an interesting image. What really surprised me was the amount visible using the dual band and OSC combination.



The animation is just a way of showing how much of an effect the H-alpha makes. You will need to click the link to view the animation.
https://cdn.astrobin.com/images/25750/2 ... da8cdd.gif

The Ha/O3 dual band IDAS NBZ UHS filter really brings something quite lovely to M45. I split the channels to create the Ha and O3 data channels that were then added with continuum subtracted techniques so not to contaminate the overall main colour. Although the O3 did contain some signal it seemed to get lost in the RGB data and only create a colour cast that then needed to be corrected out. So I am not sure what benefit it brought in this case.

I've been waiting a long time for this shot!

The old church at Mwnt is one of my favourite places for night sky photography and when I saw that amazing northern lights forecast last week I knew I had to head to the Ceredigion coast to try to capture it. Worth the trip, I hope you agree!

“Whirling Lights”: M83 – The Southern Pinwheel Galaxy

This stunning barred spiral galaxy, also known as M83, lies 15 million light-years away in the constellation Hydra. It’s one of the closest and brightest barred spiral galaxies in our sky, known for its vibrant star formation and chaotic supernova remnants scattered throughout its arms.

Bringing this galaxy to life with a 30yo scope felt like connecting the old and new. This telescope, paired with modern technology, still manages to reveal the breathtaking beauty of the cosmos. There’s something magical about capturing these distant wonders with gear that has seen so many skies over the decades.

Hello everybody,

these days the Comet C/2023 A3 Tsuchinshan-ATLAS is being so popular.
Here my contribution with two photos taken in Rome, Italy.

The first one has been taken in Sep 30th at about 6 a.m. CET, right before sunrise.
Second one has been taken yesterday, Oct 15th at 18:49 CET.


by Emanuele Colonnelli, on Flickr
The photo above was taken on September 30th, just before dawn, from a hill near the center of Rome. You can see a panoramic view of the entire city and the distant mountains. The comet was clearly visible despite the first light of dawn


by Emanuele Colonnelli, on Flickr
The photo above is a composite of two images taken with a tripod using an Olympus OM-1 and M.Zuiko 40-150mm f/2.8 lens at 40mm and f/2.8. The location is known as the "Park of the Aqueducts," named after the well-preserved ruins of the ancient Roman aqueduct that once carried water from the mountains to the city center nearly 2,000 years ago.

Cheers,

Title:
Omega Nebula - Cosmic inferno


M17 Omega NB by Giancarlo Melis, su Flickr

Full res image:
https://flic.kr/p/2qo63ti

Description:

The Omega Nebula, or M17, is one of the brightest and most spectacular nebulas, often featured in the old astronomy books I read as a child.
This star-forming region, located in the constellation Sagittarius about 5,000-6,000 light-years from Earth, has captured my attention since I was young.
Spanning 15 light-years and composed of ionized gas and dust, it shines thanks to the massive young stars within it.
Fascinated by the historic images in star atlases, having moved to a dark place with an unobstructed southern horizon,
I decided to capture M17 with my amateur equipment.

Date and Location:

Date: Fri Jul 12th 2024 starting at 10:30 pm
Barrali is a small village in the south of Sardinia, Italy.
I live in a place where light pollution is low (Bortle 4).
My shootings are made from my backyard;
I live on the outskirts and can capture the entire sky without obstructions.

Technical data:

This picture was obtained by the well-known technique of image stacking.
To emphasize the haziness of the emission in the HII wavelength, I used a bi-narrow-band filter (HII+OIII).
Because the camera I use has a reduced dynamic range, I performed a session of short shots to capture the stars that, at long exposures, are generally oversaturated.
The nebulosity was instead captured with exposures of 2 minutes each.
I applied an HOO palette in processing to make the most of the dual narrowband filter Ha and OIII.


Imaging scope: Celestron RASA 8 (400mm @f/2)
Imaging camera: ZWO ASI 183 MC-Pro
Guiding scope: ZWO Mini guide (168mm)
Guiding camera: ZWO ASI 120 M-Mini
Filter: IDAS Nebula Booster NBZ (Ha+OIII)
Lights: 30x10sec (stars) + 164x120sec (nebula)

Comet C/2023 A3 Tsuchinshan - Atlas from Meteora Greece!

We had a very stressful adventure yesterday to be able and travel on time to the wonderful site of Meteora Greece to capture the comet. The image is an integration of 520sec for the sky and the ground below with a Sony A7s full frame dslr and a 24mm lens set at f/4. The bright moonlight did make the process a lot harder but it also lit the majestic rocks of Meteora (we actually call them meteora in Greek!)

This is the third comet I image from that location and finally we get to see one at the right moment and location in the nightsky!!!

Sending my best regards to all the imagers out there and enjoy the comet for as long as it is visible.

I went chasing the comet a couple of nights this past weekend. On October 12th, it made its closest approach to Earth and was brighter than Jupiter, visible to the naked eye just after sunset. It was a rare sight in our evening sky to see something that traveled from the outer reaches of our solar system. This image was shot from the summit of Brasstown Bald in Georgia, USA

The Fighting Dragons of Ara nebula is a spectacular sight in the southern sky. It gets its dramatic name from the way its gas clouds and dust formations resemble two intertwined, battling dragons. Located within the constellation Ara, this emission nebula is a rich tapestry of star-forming regions, with bright young stars illuminating the swirling gas around them. The contrast between the glowing hydrogen gas and the dark interstellar dust lanes creates an almost mythical, mesmerizing scene. The universe at its most cinematic.

Dear APOD editors,

I would like to share with you this image of the Comet C/2023 A3 captured just 40km from the light polluted Barcelona city center.



Is it possible to see the Comet C/2023 A3 from the Barcelona region? The night of the Sunday 13th of October 2024 we drove almost 100km from our home dark sky in Prades in order to see the comet for the first time. Close to Barcelona city we found a hill, close to the Turó de l'Avellana summit (717 m above sea level), high enough to see the comet above the central mountain ranges of central Catalonia (Serra de Miralles among others).

The image shown is the result of a stacked image and the landscape image, both captured the same night within minutes of delay.

Details:

Comet: 10" image 400ISO f/2.0 tracked 18:29 UTC
Landscape: 0.8" 2500ISO f/6.3 17:57 UTC

Title : The Tsuchinshan-Atlas Comet Over a Neolithic Menhir (France)
Copyright ; Julien Looten (https://linktr.ee/julienlootenphotographie)
France.



Discovered in January 2023, the comet C/2023 A3 Tsuchinshan-ATLAS quickly captured the attention of astronomers and stargazing enthusiasts alike. It takes its name from two observatories: the Tsuchinshan Observatory in China and the ATLAS system (Asteroid Terrestrial-impact Last Alert System) based in South Africa.

This comet follows an extremely long orbit, with a cycle of about 80,000 years, meaning it hasn’t been observed since the Middle Paleolithic era, a time when Homo sapiens had not yet reached Europe. Some have dubbed it the “comet of the century,” although this title might be a bit exaggerated, even if the view is worth the praise.

As comets approach our star, the ice within their core sublimates, releasing a long trail of dust that reflects sunlight, creating a spectacular glow.

Over the past week, weather conditions have often made observing the comet difficult, especially in northern France (unsurprisingly), missing its optimal visibility period. However, tonight a brief break in the clouds allowed for a photograph to be taken. Here it is, seen over a Neolithic menhir (from the time when humans were settling), located near Arras in the Pas-de-Calais.

The comet will remain visible in the coming days, gradually moving farther away from Earth. If the weather holds, grab your binoculars and look southwest to west at dusk!

Hello and thank you in advance for taking my upcoming submission into consideration.

The image I'm submitting is an integration of Planetary Nebula SH2-188.

The data was acquired in the following dates:
06.08.2024, 07.08.2024, 10.08.2024, 11.08.2024, 05.09.2024, 06.09.2024, 07.09.2024, 08.09.2024, 09.09.2024, 13.09.2024 [dd/mm/yyyy]

Location:
Dâmbovița, România

My name:
Radu Marinescu

Total integration time:
33h 10′

Description:
With its one-sided, semicircular, filamentary gas structure, SH2-188 is a weak and unusual planetary nebula in the Cassiopeia Constellation. It represents one of the most extreme examples of interstellar medium contact, or how planetary nebulas interact with space. It is a good candidate for examining ISM effects because of its large angular dimension (in comparison to many oother such nebulae) and apparent high proper motion. The central star of Sh2-188 is an evolved entity that has shed most of its material and is on the verge of transitioning into the white dwarf phase. Based on its age and structure, it is generally thought to be an old planetary nebula. It is located at a distance of around 850 light-years, close to Ruchbach Star and was photographed for the first time in 1965 by Gaze V.F. and Shain G.A.

Equipment:
SkyWatcher 10" 250PDS / 250mm 1200mm, Hypertuned EQ6R-Pro, ZWO ASI294MM Pro, ZWO EAF, ZWO EFW, ZWO LRGBHSO, ZWO OAG w/ ZWO ASI120MM-Mini

Processing details:
Pixinsight - WBPP, local normalization, DBE with GraXpert, SCNR, generalised hyperbolic stretch, local histogram equalization, wavelet transformation, HDR combination for the faint and bright regions of the Ha, narrowband combination, narrowband normalization, selective color correction, noise reduction with a blending between NXT, GraXpert Denoise and Topaz Denoise for an ultra clean result. Sharepening and detail enhancement was only performed by deconvolution with BXT and wavelets.
Stars were processed separately, SXT, SCNR, morphological transformation to fix saturated star cores typical for Newtonian, lightness reduction by iterative stretching and deconvolution, selective color saturation. Small final touches, crop and export from Photoshop.

NGC 281 The Pacman Nebulae

The Pacman Nebula (NGC 281) is a cosmic cloud of space gas located in the constellation Cassiopeia.

The nebula’s resemblance to the classic video game character Pac-Man is quite striking, and it’s interesting that it can also look like a heart from certain angles.

NGC 281 is a rather diffuse red-glowing emission nebula. It includes a small, yet noticeable open star cluster (IC 1590) and dynamic dust lanes located in the middle of th image.

Take a look at the famous Bock globules which are small isolated dark nebulae containing dense amounts of dust and gas that are the formation of new stars.

Below are the details of this image taken in our backyard observatory.
