Story:

This picture was taken on march 25, 2023 at 21:15 from the slopes of Llaima volcano (Conguillío National Park) in Araucanía region in Chile. We can see the moon and pleiades conjunction, Venus, Urano, Mars and Orion among others.
In the foreground we can see some araucaria trees, commonly called the monkey puzzle tree, monkey tail tree, piñonero, pewen or Chilean pine, which is an evergreen tree native to central and southern Chile and western Argentina, in fact the distribution is bouded between the 37th parallel south and 40th parallel south, mostly in the chilean part of the Andes. Because of the prevalence of similar species in ancient prehistory, it is sometimes called a living fossil; individuals can achieve ages beyond 1,000 years. In this park was filmed the BBC documentary "Walking with Dinosaurs" (1999) for it resemblance to prehistoric landscapes of volcanoes, lagoons and araucaria trees. More recently it was part of the 2022 Netflix documentary "Our Great National Parks" (Episode 2: Chilean Patagonia), presented by former president of the United States Barack Obama.

Hello and welcome to Starship Asterisk*! That's a very fine image that you posted. I particularly appreciate the annotated version, because at first I couldn't make head or tails of your image. That's because the constellations are "upside down" from a northerner's point of view! Of course there is no "up" or "down" in space, so I reacted from my personal bias. Anyway, your annotated image is so helpful, and it is impressive that you managed to cram four planets into one picture and show us the Moon/Pleiades conjunction as well!

Ann

Thanks so much Ann

IC 2631 is a fascinating deep sky object located in the southern constellation of Chameleon. This object is a reflection nebula, which means that it shines not by emitting light, but by reflecting the light of nearby stars.

The nebula is illuminated by a young, hot star located in its center, which is responsible for the blue tint of the nebula. This star is a member of a small cluster of stars known as Collinder 135, which is also located within the nebula. The cluster contains around 10 stars, but only a few are visible in most amateur telescopes.

The nebula is approximately 600 light-years away from Earth and spans about 10 light-years across. It is surrounded by a complex network of dark dust clouds, which create intricate patterns and shapes when viewed through a telescope. The dust clouds also block the light from distant stars, creating a dark lane that runs through the center of the nebula.

Overall, IC 2631 is a beautiful and intriguing deep sky object that is worth observing or photographing for anyone interested in astrophotography or amateur astronomy. Its striking appearance and location in the southern skies make it a popular target among stargazers in the southern hemisphere.

The spiral galaxy M83 is located “only” twelve million light-years away in the southern constellation of Hydra. The spiral arms give this galaxy the name Southern Pinwheel. The reddish regions of star formation that dot them, highlighted in this image by the addition of the "narrow-band" hydrogen signal that constitutes them, also suggest another nickname, the Thousand Rubies Galaxy.
The image is the result of about 5h of exposure acquired in multiple sessions remotely from Australia during March 2023.

5 year anniversary!

I finally got my mosaic photo of the Milky Way. The problem was caused by the weather in the northern hemisphere, as well as atmospheric light, which left many gradients behind.
I returned to the picture several times and messed it up several times, but now I feel for weeks that I managed to finish it.

The Orion Mosaic - 25 Panels

Orion Mosaic Final APOD by Ahmed Waddah, on Flickr

This is an integration of 25 panels of the Orion constellation region imaged over the last 2 years. I had intended to add some more integration to the outer regions to bring out more details but got involved in other projects that consumed my night sky imaging time. I will complete this project later this year when Orion is back in the sky with enough time. Processing and editing the image must have been the hardest one so far as there are various regions with variant illuminations mainly the Orion Nebula area and other.

The great Andromeda Galaxy, our nearest galactic neighbor at 2.5million light years away. Like the Milky Way, Andromeda is a Spiral Galaxy. The galaxy is actually visible to the naked eye but looks like a small fuzzy patch in the sky. In the next 4-5 billion years Andromeda and the Milky Way are set to collide and will form a large elliptical galaxy.

Submission on behalf of ShaRA Team

https://live.staticflickr.com/65535/528 ... ff98_h.jpg

I am super thrilled to share on behalf of the ShaRA team our take on the so-called “GUM 14 & 15”. A challenging target and yet successfully handled by our team.

What does the ShaRA acronym stand for? In a nutshell, it’s a new open project called Shared Remote Astrophotography, acronym “ShaRA”, and is based on crowd or group funding for buying imaging time on large telescopes around the world. The project was born a few months ago.

For this image, more than a dozen of highly motivated astrophotographers combined their skills to publish such a beautiful image. To get to this level of details, the group rent over several nights a Riccardi-Honders RH 200 scope located in the Southern Hemisphere, i.e., Rio Hurtado, Chile. The colors palette of the image is obtained by combining different wavelengths together, namely Ha, Oiii, and LRGB filters.

Coming back to the target, it boiled down like killing more than two birds with one stone; two little-photographed nebulae in the Southern Hemisphere, located in the constellation of Vela and apparently linked to each other. GUM14, the largest, is an emission nebula excited by a class O blue supergiant and prospectively adjacent to a complex of reflection nebulae the most important of which is NGC2626. GUM15 is another emission nebula which, together with GUM14, belongs to the Vela Molecular Ridge: a mega molecular complex full of young and hot stars, which, thanks to their radiation, becomes visible to our telescopes.

M81 and M82 with IFN

M81 M82 and IFN by Carlos Uriarte, en Flickr
From March 13 th to April 22nd, 2023
28h integration
Sure, here's the translation of the text:

Messier 81 and Messier 82 are two galaxies located in the constellation Ursa Major. Messier 81 is a spiral galaxy, about 11.8 million light-years away from Earth, with a diameter of about 90,000 light-years. Its spiral arms contain many HII regions, where new stars are born, and it has an active galactic nucleus, indicating the presence of a supermassive black hole at its center.

Messier 82, also known as the Cigar Galaxy, is a starburst galaxy about 12 million light-years away from Earth. It is undergoing a period of intense star formation, resulting in the formation of massive, luminous stars. The galaxy is also experiencing strong stellar winds and supernova explosions, which are believed to be the source of the faint, diffuse emission known as Integrated Flux Nebula (IFN) that surrounds the galaxy.

NGC 3077 is another galaxy located near Messier 81 and Messier 82. It is a dwarf irregular galaxy, about 12 million light-years away from Earth, and it is known for its high levels of star formation activity. The galaxy has several bright HII regions and is also believed to be a source of IFN.

The Rosette Nebula (also known as NGC 2237 and C 49) is a large, roughly circular H II region located on the edge of a giant molecular nebula in the constellation Unicorn.

The nebula has an angular diameter of 1.3° and is located at a distance of 1600 parsecs (about 5200 light years) from the solar system; it is approximately 100 light-years in size.

At the center of the Rosette Nebula is a bright open cluster known as NGC 2244; the blue stars of the cluster, forming part of the OB association known as Monoceros OB2, emit ultraviolet radiation, which excites the gas of the nebula leading it to emit red light. The stellar wind from the O and B group of stars is thought to exert pressure on the interstellar cloud causing compression, followed by star formation; in fact, many Bok globules have been observed in the region, believed to be the site of star formation.

NGC 2264

NGC 2264 indicates a bright open cluster surrounded by a large system of diffuse nebulosities, within the constellation of the Unicorn.

In fact, the first striking feature when exploring this area of the sky with binoculars is a group of about twenty blue stars, dominated by the star S Monocerotis, of magnitude between the fifth and ninth, arranged in a triangle, with the vertex pointed towards the south, a feature that in the southern hemisphere (where the top appears to be pointing upwards) makes it similar to a Christmas tree (the latter is the proper name of the cluster).

In the southern apex of the cluster, if observed with a Newtonian telescope with the aid of a filter, a nebula becomes evident, in the edge of which there is a dark patch in the shape of a cone with the tip directed towards the apex of the shaft of Christmas; this structure has made the cloud famous with the proper name of the Cone Nebula. A vast fainter nebulosity also extends to the northwest of the cluster, clearly visible in long-exposure photos.

Cocoon Nebula · IC 5146

14/04/2022 15/04/2023

IC 5146 Cocoon Nebula
IC 5146, (also known as C 19), is an open cluster attached to a diffuse nebula visible in the constellation Cygnus.
The nebula is an agglomeration of gas and dust containing young stars that have excavated its interior, as happens in M 42. The nebula is rich in hydrogen, it is an HII region, which emits light by emission and is the one that it is referred to as a "star factory". It has an overall magnitude of 7.2 and is about half as wide as the lunar disk. It has an irregular shape, even if roughly rounded, with a real diameter of about 15 light years and is found inside an open cluster, in which there are several stars suspected of being variable, which illuminate part of it also by reflection.
The brightest star of the open cluster has a magnitude of 9.74, an age of about one hundred thousand years, but probably it is not part of it (it overlaps the cluster prospectively), as its distance seems different from that of the cluster is equal to only 3,300 light years.
Steve Coe's commentary reports that the nebula and cluster are about one degree distant from a dark matter filament Barnard 168 (B 168), which extends about two degrees and projects onto the disk of the Milky Way. The dark nebula is clearly visible in Ligustri's image: it is the dark filament that surrounds the nebula and moves away to the right.

The Orion Nebula; a bright spot in the sky that attracts the attention of all astronomical photographers and observers alike. This is the first enticement for most astronomical photographers, only perhaps preceded by the moon. The journey often starts with capturing the most observed phenomena in human history. After engaging in astrophotography, capturing thousands of other characters, obtaining countless photos and observations, and buying lots of expensive equipment, you will eventually find yourself returning again to the Orion Nebula.
Photographing the Orion Nebula is one of the most difficult phenomena to photograph, as the gradation of lighting will be your first dilemma… but comparing the results of your journey will never cease to impress… all thanks to the Orion Nebula.

And the end of all our exploring

Galaxy Triplet NGC 6769-71 by William Ostling, on Flickr

Full write-up here: https://theastroenthusiast.com/galaxy-t ... c-6769-71/\

This is another image from telescope live, of an interacting galaxy triplet plus some friends in the background. It was a really tough dataset to process – the data was badly undersampled and slighly out of focus. Very careful work with GHS and MMT helped a lot with this image, and I’m pretty happy with the amount of detail I got out considering the lack of data.

Galaxy Triplet NGC 6769-71 is a gravitational interacting triplet of galaxies, located about 190 million light years away in the southern constellation of Pavo (the Peacock).

Most galaxies are members of clusters of galaxies. In these, they move around among each other in a mostly slow and graceful ballet. But every now and then, two or more of the members may get too close for comfort – the movements become hectic, sometimes indeed dramatic, as when galaxies end up colliding. This image shows an example of such a cosmic tango.

As dramatic and destructive as this may seem, such an interaction event is also an enrichment, a true baby-star boom. A cosmic catastrophe like this one normally results in the formation of many new stars. This is obvious from the blueish nature of the spiral arms in NGC 6769 (upper right) and NGC 6770 (upper left) and the presence of many sites of star forming regions.

This really was lucky imaging. As I was imaging the Sun's photosphere and active regions a 737 flying from London to Gran Canaria made a centre-stage cameo appearance. It made me ponder the possibilities if humans really could fly to different star systems.

Eight active regions can be seen, regions 3279 (lower left), 3282 (upper left) and 3280 (right middle) containing 18, 17 and 14 individual sunspots respectively.

Date: 15th April 2023. Taken with an 80mm diameter/400mm fl refracting telescope fitted with a Herschel wedge and ZWO planetary imaging camera.
