Re: Submissions: 2023 April
I would have loved to comment more on the pictures posted here in the Recent Submissions thread, but I'm too tired to do it these days. But I'll do it now, because you specifically asked for feedback, and this is only your third post here at Starship Asterisk*.Altrmike wrote: ↑Sun Apr 23, 2023 9:32 pm
NGC 5033 and others
So when planning this imaging session I wanted to choose something that may not be images alot....taking the road less travelled potentially and boy am i happy i did I have spent multiple weeks under botle 4 skys and an average of 25% moon to capture this gem. In this craft of astrophotography there are always ups and downs and things to learn within and without I have come along way but am still learning every time i sit out under that night sky. let me know your thoughts and i hope you enjoy my attempt at NGC 5033
if youd like to check out the full resolution image you can find it here https://www.astrobin.com/full/t28de5/0/
NGC 5033 is an inclined spiral galaxy located in the constellation Canes Venatici. Distance estimates vary from between 38 and 60 million light years from the Milky Way. The galaxy has a very bright nucleus and a relatively faint disk.
NGC 5033 contains a Seyfert nucleus, a type of active galactic nucleus. Like many other active galactic nuclei, this galaxy's nucleus is thought to contain a supermassive black hole. The bright emission seen in visible light (as well as other wavebands) is partially produced by the hot gas in the environment around this black hole.
Integral field spectroscopic observations of the center of NGC 5033 indicate that the Seyfert nucleus is not located at the kinematic center of the galaxy (the point around which the stars in the galaxies rotate). This has been interpreted as evidence that this galaxy has undergone a merger. The displacement of the Seyfert nucleus from the kinematic center may destabilize the rotation of gas in the center of the galaxy, which could cause gas to fall into the Seyfert nucleus. The gas would be compressed by the enormous gravitational forces in the center of the Seyfert nucleus and become hot, thus making the nucleus appear bright or "active".

I like your picture a lot! What I like best about it is that you included NGC 5005 in your picture of NGC 5033, so that we could marvel at the fantastic contrast between these two galaxies. NGC 5033 has a small yellow center and large loose blue arms, but NGC 5005 has a tightly wound bright yellow arms, which makes the entire galaxy look like a yellow lenticular galaxy. (NGC 5005 is quite similar to NGC 2841.) How fascinating! I think your image benefits enormously from your choice of showing us this contrast.
I also very much appreciate the annotated version of your image. By the way, I think that the very blue object at lower left in your image is irregular galaxy UGC 8303. (Well, Simbad Astronomical Database calls it a galaxy in a pair of galaxies.)

Re: Submissions: 2023 April
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!Vitopastorini wrote: ↑Mon Apr 10, 2023 5:10 am hi! this is my very first post in the Forum, hope you like it.
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.

The Pinwheel Galaxy
The galaxy Messier 101 is a swirling spiral of stars, gas, and dust. Messier 101 is nearly twice as wide as our Milky Way Galaxy.
Messier 101 has a pancake-like shape that we view face-on. This perspective shows off the spiral structure that gives it the nickname the Pinwheel Galaxy.
The Pinwheel Galaxy is a face-on spiral galaxy distanced 21 million light-years away from earth in the constellation Ursa Major.

Fly me to the stars.
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.

Gum 12b IG by Ahmed Waddah, on Flickr
Gum 12b is part of the Gum Nebula in the southern constellations of Antlia, Vela and Puppis. I had 2 hours for the target just before it went under the horizon. Its nice to image a target that is rarely imagined, and hopefully, next year, I do narrow band on the target get more details as its a dim target.

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.

IC 405 shines due to the radiation received from AE Aurigae, which ionizes its gases and gives it a red colour. the blue structures are instead due to the reflection of the blue light of the star on the dark dust.

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.

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.

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.

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.

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.

M81 and M82 with IFN

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.

Re: Submissions: 2023 April
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.
