Crux and Coalsack on fire
The Coalsack dark nebula and the Southern Cross against the backdrop of the Milky Way, adorned with hydrogen nebulae that belong to the so-called Coalsack Loop. It looks a bit as if someone placed this Coalsack on embers - hence probably all the dust around it.

IC 5146 (also Caldwell 19, Sh 2-125, Barnard 168, and the Cocoon Nebula) is a reflection[2]/emission[3] nebula and Caldwell object in the constellation Cygnus. The NGC description refers to IC 5146 as a cluster of 9.5 mag stars involved in a bright and dark nebula. The cluster is also known as Collinder 470.[4] It shines at magnitude +10.0[5]/+9.3[3]/+7.2.[6] Its celestial coordinates are RA 21h 53.5m , dec +47° 16′. It is located near the naked-eye star Pi Cygni, the open cluster NGC 7209 in Lacerta, and the bright open cluster M39.[2][5] The cluster is about 4,000 ly away, and the central star that lights it formed about 100,000 years ago;[7] the nebula is about 12 arcmins across, which is equivalent to a span of 15 light years.[6]
When viewing IC 5146, dark nebula Barnard 168 (B168) is an inseparable part of the experience, forming a dark lane that surrounds the cluster and projects westward forming the appearance of a trail behind the Cocoon.

NGC 6888 - The Crescent Nebula
Dear all,
Greetings from Switzerland!
I hope this email finds you well and in good health! I would like to share my latest work - NGC 6888, The Crescent nebula.
Below is a brief description of the object I always like to share and also some challenges I faced during the light acquisition and elaboration.
In a hot summer evening, way back in 1792, Mr. William Herschel pointed his telescope at the main constellation of the summer sky, the Swan, more precisely, near the star Sadr. He never imagined what he would see. A shock wave caused by the explosion of a red giant 250,000 years ago. This red giant, now close to its death, began to grow larger and larger until it exploded through a thermo-nuclear fusion reaction of its core. The instant after its explosion, the cosmic chaos. Shock waves from the explosion collide with each other, glowing gases and cosmic winds intersect, giving rise to a beautiful nebula.
This nebula, called ‘Crescent’ or NGC 6888, is a ‘bubble’ of stellar wind generated by the explosion of the star HD 192163 that lies within it. This star is still 500,000 times brighter than the Sun and is very young, only 4.5 million years old (almost a thousandth of the age of our Sun).
This nebula is located 4,700 light years from us and has a size, along its longest side, of about 16 light years.
The most challenging part of the acquisition is was to wait the best conditions for the narrowband and RGB. The idea was to acquire the lights in narrowband for the nebulas and, then, the RGB for the stars to be then elaborated separately. ALso the elaboration was quite challenging as the faint blue shades surrounding the nebula were elaborated taking a particular care to let them be seen.
The photo is a sum of about 124hours of exposure time with:
Camera: ZWO ASI 6200 mono
Telescope: Tecnosky fast 300 mm - 12''
Filters: Chroma Technology HSORGB
Chroma Blue 50 mm: 33×600″(5h 30′)
Chroma Green 50 mm: 31×600″
Chroma H-alpha 3nm 50 mm: 174×900″
Chroma OIII 3nm 50 mm: 114×900″
Chroma Red 50 mm: 41×600″
Chroma SII 3nm 50 mm: 138×900″
Mount: iOptron CEM 120
The picture was taken between May 15th 2024 and June 20th 2024 from Castillejar, Andalusia, Spain by Alex Battù and Luca Barcaro, named: Astrodivers - https://www.instagram.com/theastrodivers/
Thanks for your consideration.

This nebula, called ‘Crescent’ or NGC 6888, is a ‘bubble’ of stellar wind generated by the explosion of the star HD 192163 that lies within it. This star is still 500,000 times brighter than the Sun and is very young, only 4.5 million years old (almost a thousandth of the age of our Sun).
This nebula is located 4,700 light years from us and has a size, along its longest side, of about 16 light years.
The most challenging part of the acquisition is was to wait the best conditions for the narrowband and RGB. The idea was to acquire the lights in narrowband for the nebulas and, then, the RGB for the stars to be then elaborated separately. ALso the elaboration was quite challenging as the faint blue shades surrounding the nebula were elaborated taking a particular care to let them be seen.
The photo is a sum of about 124hours of exposure time with:
Camera: ZWO ASI 6200 mono
Telescope: Tecnosky fast 300 mm - 12''
Filters: Chroma Technology HSORGB
Chroma Blue 50 mm: 33×600″(5h 30′)
Chroma Green 50 mm: 31×600″
Chroma H-alpha 3nm 50 mm: 174×900″
Chroma OIII 3nm 50 mm: 114×900″
Chroma Red 50 mm: 41×600″
Chroma SII 3nm 50 mm: 138×900″
Mount: iOptron CEM 120
The picture was taken between May 15th 2024 and June 20th 2024 from Castillejar, Andalusia, Spain by Alex Battù and Luca Barcaro, named: Astrodivers - https://www.instagram.com/theastrodivers/

I dedicated an entire day to gathering and processing solar images across various wavelengths. This data was obtained using a 50mm telescope equipped with a spectroheliograph. The range of wavelengths spanned from near-infrared to ultraviolet. I hope you find them as fascinating as I do.

The Triangulum Galaxy, also known as Messier 33 or NGC 598, is a spiral galaxy located 2.73 million light-years from Earth in the constellation of Triangulum. It boasts a D25 isophotal diameter of 18.74 kiloparsecs (61,100 light-years), making it the third-largest galaxy in the Local Group, following the Andromeda Galaxy and the Milky Way.
A total of 60 frames with a 20-second exposure over 20 minutes were composited atop 77 frames with a 10-second exposure over 12 minutes using seestar processing and color grading as the base in Photoshop, cropped to a 5x7 ratio, resulting in a total exposure time of 32 minutes.

Comet 13P/Olbers
This Halley-type comet with a period of 69 years just passed perihelion in June. Captured here is the typical green glow of the coma (from CN and C2 emissions) and just a hint of reflected sunlight from a diffuse trailing dust cloud. Very prominent is the blue ion tail which shows complex structure due to its interaction with the solar wind. This object could definitely use more exposure time, but I only have about a 60 minute window between late twilight and the comet setting below my observatory wall. Imaged on 29 July 2024 in Ursa Major.
Details:
QSI 660 camera on 250mm RC, Astronomic RGB filters.
17 minutes each red, green, and blue.
Processed with PixInsight and Photoshop.
Final image resolution 0.93 arcsec/pixel, 20 arcminute wide field.

Celestial Encounters
Copyright: Julien Looten
On the night of July 31, 2024, I traveled to Verclause, in the heart of the French Baronnies, a medieval village perched on a rocky outcrop. This picturesque location is home to the ruins of a feudal castle and a church that is currently hosting an astrophotography exhibition by Martin Lefranc.
The idea behind this composition was to capture a monument in the background with a remarkable conjunction of several celestial objects. Indeed, the Moon, illuminated at 19%, had a rendezvous with Jupiter, visible on the horizon, Mars higher in the sky, the Pleiades, an open star cluster, and even Uranus.
The thin high-altitude cloud cover also added to the evening's magic by creating a small lunar pillar. This photometeor appears when the Moon's light is reflected toward the observer by ice crystals aligned in the atmosphere.
To capture this moment, I used HDR with three photos to avoid overexposing the Moon. My equipment included a Sigma FP and a Canon 50mm f/1.8 lens.
thanks in advance,

The Pelican Nebula
Copyright: Danijel Bosnjak I am currently on vacation with the family, on the Croatian island of Korčula, in the Adriatic south. The Bortle class 2/3 skies are available from my patio so this was a relaxing few nights of quiet and solitude, enjoying the Cosmos.
This project was completed during the course of 3 consecutive nights, with partially illuminated waning crescent moon present.
The first session was on July 28/29, capturing 31x180s light frames.
The second session was on July 29/30, capturing 91x180s light frames.
The third and final session was on July 30/31,capturing 93x180s light frames.
A total of 215x180s light frames were captured, but i had to throw away 63 frames due to various issues (star trailing, focus issues, moonlight).
I ended up using the remaining 151 light frames, which equals to 7h 33m of data, plus 20 darks, bias, flats and dark flats.

Beginning of the Perseid meteor shower over the Black Desert Mountains, Egypt
The Black Desert in Egypt is part of the Western Desert and is characterized by the black color that covers most of the mountains and valleys. This color comes from basalt, the main component of the region’s rocks.
In this picture, the Milky Way shines over one of the mountains of the Black Desert while one of the famous Perseid meteors passes by, which reaches its peak a week after this picture.

Description
Deep in the cosmos, 7,000 light-years away from us, shines the Eagle Nebula, a realm of gas and dust where stars are born. This image, captured from my garden in Rome, reveals its beauty and a celestial landscape that evokes wonder and mystery.
The "Pillars of Creation" majestically emerge from the heart of the nebula, titanic columns composed of gas and dust that hold the secrets of stellar birth. Embraced in a glow of blue and gold light, these pillars represent the ongoing cycle of creation.The contrast between the incandescent shades of red and orange, and the brilliant blue of stellar radiation, reveals the inexorable dance of cosmic matter. Each color tells a story: the red and orange are the remnants of ancient stellar explosions, while the blue indicates the presence of young, radiant stars illuminating the gas with their energy.This image, created with passion and dedication under the Roman sky, is not just a window into space, but also an invitation to reflect on our existence in the vast scheme of the universe, on how our home is special and that our existence should be dedicated to exploring the infinite, uniting all humanity. Because we are stardust, and we are part of this extraordinary cosmic symphony.
