Orion's Radiant Echo: A Celestial Bond
My name is Ali Alobaidly
This is my submission for APOD, captured in Al Salmy, kuwait.
Orion's Radiant Echo: A Celestial Bond by Ali Alobaidly, on Flickr
https://live.staticflickr.com/65535/534 ... 7c15_k.jpg
Image description:
In the vast Kuwaiti desert, beneath a star-studded canvas, a 382mm telescope aimed at the heart of Orion can be a transcendent experience. The Orion Nebula, a stellar nursery, unfurls its cosmic tapestry through 17 hours of imaging—capturing both the broadband and the ethereal Hydrogen Alpha emissions. Orion, the mighty hunter, graced the ancient skies, revered by Arab astronomers for centuries. His presence was not merely myth; it was an enduring connection to the celestial wonders above. In the ancient Arab world, Orion held significance as a guide across the vast desert, a constellation embraced in stories and navigation. A resonance of ancient wisdom can still be felt in the modern era as Arab astrophotographers, heirs to the ancient stargazers, continue the tradition. I and many others can attest to it. Through advanced equipment and techniques, intricacies of Orion’s nebula brides the gap between ancient lore and contemporary exploration. 1,344 ± 20 light-years away, the crown jewel of the Milky Way spans 24 light-years of space, and so the celestial bond echoes through time and stands as a testament to the timeless curiosity that unites all those who wander.

Hi guys, I've always liked this picture and always wanted to, but I thought the light pollution would spoil the picture and it would be a wasted night, so I always used prime focus. This time I decided to go for it, and although I had to fight a lot against the LP, in the end I had a great time processing it, the main conclusion I have come to is that I must buy a quality lens, we'll see if Santa has pity on my soul next weekend hehe.
I hope you like it

The Old Man and Polaris
Location: The Stone Forest, Bulgaria
Date: 12.12.23
Story: Gazing into the night sky and spotting the North Star, you're actually looking at Polaris. It's not only the most luminous star in the Ursa Minor constellation (the Little Dipper), but its proximity to the north celestial pole (less than 1° away) renders it valuable for orienteering and navigation. Myth and science intertwine, as Polaris also symbolizes Santa's home, our most favorite old man in the entire planet.

RCW 16
RCW 16
RCW (RCW stands for Rodgers, Campbell, and Whiteoak) catalogues a series of emission nebulae found in the southern hemisphere. RCW 16, in particular, is a stunning and intricate emission nebula located in the constellation Ara in the Milky Way.
RCW 16 is an active star-forming region characterized by the presence of young, massive stars. These stars emit intense ultraviolet radiation that ionizes the surrounding hydrogen gas, causing it to glow and emit light. This emission gives RCW 16 its vibrant appearance when observed through telescopes.
The nebula showcases various structures, including intricate filaments, pillars, and dense regions of gas and dust. These features are indicative of ongoing processes of star birth and the interaction of these newborn stars with the surrounding interstellar medium.
Imaged with the Planewave CDK 24, QHY 600M camera, and Astrodon 3nm filters from El Sauce Observatory in Chile on May 5th, 2023.

The Bubble
The Bubble Nebula in the constellation, Cassiopeia. The bubble is formed from the stellar wind coming from a star about 45 times larger than our own. I shot this from Vancouver, Canada, all the way back in August 2023, over 6 nights, for a total of 28 hours of total exposure. I used my Celestron Edge HD 8", with 0.7x reducer, ASI533 MM Pro, Antlia 3nm SHO filters, and Antlia RGB filters for the stars.

The Garlic Nebula
The attached image was done from my driveway in Ellicott City, Maryland under Bortle 6 night sky. My neighbor showed me an article from ARSTechnica about the nebula so I thought I would give it a try. I originally tried with my Celestron EdgeHD 9.25 and ASI2600MC but the field of view wasn't enough to capture the whole nebula. So, I used my REDCAT 71 and ASI1600mm PRO to capture subs from three different filters (60 - Ha, 66 - Sii, 64 - Oiii) over three nights in December 2023 for almost 16 hours of imaging. Post-processing was about 8 hours.

Flaming Star Nebula (IC 405) & Tadpole Nebula (IC 410)
The Flaming Star Nebula (IC 405) is an emission and reflection nebula
approximately 1,500 light-years away. The nebula illuminated by the
hot blue variable star AE Aurigea.
The Tadpole Nebula (IC 410) is approximately 12,400 light-years away.
The tadpoles are gas globules, small dense knots of dust and gas that
give birth to young stars.

Re: Submissions: 2023 December
Although it is one of the most recognizable star groupings on the sky, Orion's icons don't look quite as colorful to the eye as they do to a camera. In this shot, cool red giant Betelgeuse takes on a strong orange tint as the brightest star at the upper left. Orion's hot blue stars are numerous, with supergiant Rigel balancing Betelgeuse at the lower right, and Bellatrix at the upper right Lined up in Orion's belt are three stars all about 1,500 light-years away, born from the constellation's well-studied interstellar clouds. Below Orion's belt a reddish and fuzzy patch that might also look familiar -- the stellar nursery known as Orion's Nebula. Finally, just barely visible to the unaided eye but quite striking here by camera is Barnard's Loop -- a huge gaseous emission nebula surrounding Orion's Belt and Nebula discovered over 100 years ago by the pioneering Orion photographer E. E. Barnard.

The Twin Stones...
https://www.flickr.com/photos/julienlooten/
Copyright: Julien LOOTEN
Last weekend (12/17/2023) I ventured to a rather unusual place... Although far from Brittany (France) and its many megalithic sites, Pas-de-Calais (France) is home to several similar sites, where you can discover standing stones, commonly known as "menhirs".
These include the "Pierres Jumelles" or "Pierres du Diable", not far from Arras. These two imposing menhirs date back to the Neolithic era, a period marked by the sedentarization of man and the development of animal husbandry and agriculture. The precise function of these stones remains enigmatic.
The largest sandstone block reaches 3.3m. Its imposing weight - eight tonnes - prompts reflection on the considerable effort required to transport it from the surrounding hills to its present location. Several local legends have the power to explain this age-old feat...
Moreover, photographing such places alone at night is a singular experience. When these ancient structures are associated with a starry sky, the mysterious character of the place is intensified.
The photograph reveals the Milky Way emerging from the two stones. The summer triangle of Deneb, Altair and Vega is clearly visible (at the end of autumn..), disappearing rapidly after sunset. The reddish hue in the Milky Way corresponds to the constellation Cygnus, home to numerous nebulae.
On the horizon, greenish and yellowish bands reveal the presence of "airglow", an atmospheric phenomenon I had captured at Château de Losse the previous winter.
Although the moon is invisible in the photo, you can easily imagine it on the left of the image, casting enough light to create the shadow of the menhir on the ground.

Re: Submissions: 2023 December
Stephan's Quintet- Don't they look a bit like Christmas Teee ornaments?
As the name suggestes this is a complex 5 galaxy group, where some galaxies are violently colliding and will likely merge together eventually. The orange coloured galaxies have a physical association, a true galaxy group, known as Hickson Compact Group 92.
Estimates place them 290 million light years away (!!) The blueish galaxy is much closer and is not connected to the others, only 40 million light years away.
These galaxies are located in the constellation Pegasus not far from the big galaxy in my last image NGC7331. This little grouping is often placed in a mosaic with that Deer Lick group.

3 hours of RBG data from 2022 (ASI 2600MC)
Processed with bias, dark and flat frames (taken twice due to light leak)
Guided with the Celestron OAG and the ASI174MM
Processed with Pixinsight, Photoshop with some Star Spikes added for fun.
Merry Christmas everyone!
Stephan's Quintet by Andrea Girones, on Flickr
As the name suggestes this is a complex 5 galaxy group, where some galaxies are violently colliding and will likely merge together eventually. The orange coloured galaxies have a physical association, a true galaxy group, known as Hickson Compact Group 92.
Estimates place them 290 million light years away (!!) The blueish galaxy is much closer and is not connected to the others, only 40 million light years away.
These galaxies are located in the constellation Pegasus not far from the big galaxy in my last image NGC7331. This little grouping is often placed in a mosaic with that Deer Lick group.

NGC7320, 7320c, 7318a 7318b 7319 and 7317 Also known as HCG92 and ARP319

Re: Submissions: 2023 December
NGC 1333 (or the Embryo Nebula) from a Bortle 1 - 31.5 hours total with the RASA 8 and ASI2600MC, no filters.
NGC 1333 is a reflection nebula in the constellation Perseus, it is also known as the Embryo Nebula. This is a bright but small object surrounded by thick interstellar dust clouds, with some of them being so thick that they completely hide the light behind them.
The Embryo nebula is part of the Perseus Molecular Cloud, which is why you can see so much dust in the background of our image. NGC 1333 is one of the best-studied regions of active star formation, and is fairly young compared to others. Within the nebula lie several star clusters which help make the gasses in the vicinity bright and colorful.
NGC 1333, with Barnard 1 and Barnard 2, is part of the L1450 dark cloud, also known as Barnard 205.

POLAR STRATOSPHERIC CLOUDS
Copyright: Alan C Tough
For the last four days very rare Polar Stratospheric (Nacreous) Clouds have been spotted all over the UK (and now continental Europe). On January 21st I was able to follow them for the entire day through gaps in the tropospheric cloud. This shot was taken about an hour before sunset.

Merry Christmas
Dear friends, I leave here in advance my sincere merry Christmas to all, may God enlighten and make a year full of achievements at all. In this medium of astrophotography I met wonderful people, friends, partners and very welcoming.
I anticipate my merry Christmas, because I will be away for a few days, so I made through the junction of two images my astronomical Christmas tree
Here in this image times:
1) cone nebula (Christmas tree): captured during the meeting in Mato Grosso: https://www.astrobin.com/full/332122/0/
2) Comet 46p / Wirtaner (would be the light at the tip of the star: https://www.astrobin.com/full/381842/0/
Some artificial spikes were placed to simulate Christmas balls.
Equipment
1) cone: Apo 80mm ts + cen60ec + asi1600mm + baader LRGB
20 * 150 "GB + 10 * 300" halpha + L
2) Comet 46p: Canon 6D + smarteq: 15 * 60 "
