NGC 7814 (également nommée Caldwell 43 et UGC 8) est une galaxie spirale distante de 53 millions d'années-lumière environ et située dans la constellation de Pégase. La galaxie est vue de profil depuis la Terre, ce qui lui a valu le nom du "Petit sombrero", en référence à la galaxie M104, qui, elle aussi, est vue depuis la tranche. (Source Wikipédia)

The Sombrero Galaxy, also known as M104 or NGC 4594, is a spiral galaxy in the constellation Virgo located 31 million LY from Earth.
The dark dust lane and the bulge give this galaxy the appearance of a sombrero.
Imaged using a 8" SCT at f6.3, 1280mm focal length, with a QHY268M camera.
The total exposure time of this image for all of the LRGB filters was 10 hours and 4 minutes.
Image was Live Stacked consisting of 24 x 5 minute exposures from my city location using the L-Pro Optolong filter and ASI2600MC camera.
What is interesting in this image is a small streak, bottom left of the galaxy. This streak is a main belt asteroid called Robelmonte. Its apparent brightness magnitude is 14.04 with a radius of 11.6 kms and traveling at about 237 million kms away from earth.
This is M104 a.k.a “The Sombrero Galaxy”. It’s the second of four images I took during the Texas Star Party trip. The Sombrero galaxy, as seen from Earth, is an edge-on spiral galaxy. It gets its name from the bright core surrounded by thick dust lanes. The galaxy is 50,000 light-years wide and is located 28 million light-years from Earth in the Virgo galaxy cluster. This image was captured in Bortle 2 skies with LRGB filters and only 6 hours of total exposure time. So coool!

This beautiful galaxy was one of the last objects added to Messier list. Today it's believed that there are two galaxies there, one elliptic inside and other spiral outside. There are few or none regions of nebula/star forming zones visible here, but many clusters orbiting the halo. And there are several galaxies background around the complete picture. LRGB for 7 hours, Telescope GSO RC 30cms, camera STF8300/AO-8 from La Colonia, Illapel, Chile.
Esta bella galaxia fue uno de los últimos objetos incluídos en el catálogo de Charles Messier. Actualmente se cree que se trata de dos galaxias, una interna elíptica y otra espiral exterior que está siendo "devorada". Llama la atención las escasas regiones de formación de estrellas, a diferencia de otras muchas galaxias. Los puntos alrededor son varios cúmulos orbitando el halo galactico. Hay varias galaxias pequeñas en el fondo, por todo el campo. Composición LRGB por 7 horas, telescopio GSO RC 30cms, cámara STF8300/AO8, desde la Colonia, Illapel, Chile...

Is it a bird, is it a plane, is it a UFO??? No it's M104
Hovering like a flying saucer M104 is one of the most striking galaxies in the sky.
The light from this galaxy took some 40 Million years to reach my camera and it is indeed sobering to think that when this light left M104 mammals were in their infancy on Earth and humans were but a glimmer in the far distant future!

Sombrero Galaxy
This is a really interesting object that everyone seems to remember. The Sombrero Galaxy, also known as M104 or NGC 4594 is located in the constellation Virgo. It’s smaller than our galaxy, measuring 50,000 light years across. It has a very large central bulge and an incredible dust lane in its inclined disk. This is where it gets its name from as it has an appearance of a sombrero. This galaxy hosts a supermassive black hole. In fact it is one of the most massive black holes measured in any nearby galaxies. The speed of revolution of the stars within the centre of the galaxy could not be maintained unless a mass of 1 billion times the mass of our Sun is present in the centre.
This is a full frame image. The galaxy’s orientation is dictated by the only guide star I could use, so it may look a bit off. After all, there really is no right or wrong way up. Cropping the image would allow for a more tradition presentation, but I really wanted to show as much of the field as possible. It’s full of galaxies. That’s so cool.

The Sombrero Galaxy, Messier 104 (M104) is in the constellation Virgo. From my vantage point, it just makes it high enough over the roof of my house to snap a few pictures. The image below was taken on April 24, 2016 using a Canon 6D, Meade 12” LX90, both mounted on a Celestron CGEM-DX mount, unguided. I used a mix of 15-second exposure at ISO 5000 and 6400 to combine 7-minutes of data. I tried several targets, all less than 10-minutes total exposure time so I could test out my collimation of the Meade telescope.
I used the following software packages in producing this image: DeepSkyStacker, ImagesPlus, Adobe Lightroom, and Corel Paintshop Pro.
The Sombrero Galaxy is about 50,000,000 light years away with an apparent magnitude of 8.3.

A pair of brand new MCW Metrobuses seen prior to entering service, at the Aldenham Works open day in September 1979.
I watched this fellow for a while, mostly because he was making a fairly loud racket. Indeed, I thought the police were going to have some words with him when they pulled up in their car. But the two ignored each other, and the police car quickly zoomed off somewhere else.
It turned out that the man was waiting for the M104 bus to arrive; the Verizon sign that you see on the left side of the picture is actually part of the "wall" of a bus-stop shelter. The bus eventually arrived, and the man got on the bus, and that was the end of this little mini-drama.
I watched carefully on each of the 14 days I spent at the Earth Cafe, and never saw the man again. With his bushy beard, it would be hard to miss him ... but it just demonstrates that some patterns do not repeat.
**********************
As I’ve mentioned in a couple of recent Tumblr blog postings, I’m working on an exercise for a new class that I’ve started taking at the International Center of Photography (ICP) in the fall of 2015.( You can see the earlier Tumblr postings here and here.)
In addition to taking a bunch of photos (see the other Tumblr postings for details and descriptions of what the photos are supposed to illustrate), we also have the task of editing our images down to a maximum of 10 “presentation images” that we will share with the ICP class next week. When our instructor, Joanne Dugan, asked me last week if I anticipated having any problems with this aspect of the assignment, I shrugged and said, “No, I do this all the time …”
Well, yes and no: I do do a lot of editing/winnowing of my photos before deciding which ones should be shared with anyone else. But I had forgotten that I also do a lot of cropping, color-adjustment, tweaking, and general post-processing before I upload my photos to Flickr, Facebook, or even Instagram. For this particular ICP exercise, we were also told not to crop the photos, and not to do any post-processing. That makes things a lot more difficult …
On the other hand, part of the exercise is to assemble and share a maximum of ten photos that collectively tell a “story” of some kind – and to “tell” that story with anywhere from a word, to a sentence, to a paragraph for each of the photos. That makes things a lot easier … after all, if a photo has to be presented in isolation, then it truly stands alone. And it is intended to be viewed without any accompanying text, then it really stands alone. There’s nothing wrong with that; indeed, one might argue that that’s the whole point of photography: a picture should “tell” a story all by itself, without any extraneous verbiage to “explain” what might not be obvious to the viewer.
But not very many things exist in complete isolation of the rest of the universe, especially in today’s interconnected world. I suppose some people would debate that point quite vigorously; and some people might argue that a photograph of a person, place, or thing should be able to “stand alone” without anything else. I certainly have seen photos that fall into this category, and I suppose I’ve taken a few like that, too. Or, maybe if I never intended my photos to be considered in complete isolation from one another, perhaps that’s how some people prefer to look at them …
But for me, that’s a pretty rare phenomenon. Almost always, I find myself telling a story. The photographs obviously present one “dimension” of the story, in a visual form; and I’ve been trying to remind myself lately that videos can present can present one, and sometimes two, additional dimensions (motion and sound) that can add enormously to the viewer’s understanding and appreciation of the underlying story.
But even if one uses only traditional photos, I find that it’s almost impossible for me to crate (or make, or take) one photo by itself; invariably, I take dozens, if not hundreds or even thousands, which collectively tell a story. It may be a story about someplace I’ve been, or some event in which I’ve participated, or some individual (or group of individuals) that I want the viewer to know and appreciate in more detail than would be possible to communicate in a single photo.
And then there are the words … maybe it’s because I spend part of my time as a writer and teacher that I find it almost impossible not to augment my photos with words. Lots of words. Indeed, sometimes far too many words; and sometimes clumsy words, or the wrong words. And I do realize that there are times when the situation would be improved if I would just shut up, and let the photograph do all of the communication. But for better or worse, I guess I’m a photojournalist.
With that in mind, I began the process of editing the photos for my recent ICP assignment. Here’s what I found:
1. It’s not as easy as one might think, when you start with a large number. I began winnowing the original images when I had 2,700 (after 9 days of shooting), and I still had 5 days of shooting left).
2. It’s much more difficult than I had imagined, given the constraints of my ICP class: no cropping, no post-processing, and a maximum of only 10 images. I’ve worked within those constraints for the final images that I’m submitting to the ICP class; but for these Flickr uploads, I’ve ended up with 40-45 images – and they have been heavily cropped, tilted, color-corrected, noise-dusted, and tweaked in various other ways. C’est la vie…
3. Using the collection of photos to “tell a story” is both easier and harder than I thought it would be. I’m including these background notes in all of the photos that get uploaded to Flickr … because I’ve learned (form past experience) that some visitor will zoom in on just one particular photo, without necessarily looking at all of them, and/or without seeing the overall notes for the entire album. And I don’t think I’ll find it difficult to write a few sentences to provide the background details for each photo … but whether they “flow” and create one overall, coherent “story” remains to be seen.
4. Aside from a narrative “story,” there are some “themes” that I noticed throughout this entire two-week exercise. The most significant one was exactly what I had anticipated: patterns. If you are lucky enough to sit in the same spot at the same time, day after day, you see the same rhythms, the same people, the same repetitions of life’s little actions and emotions. Many people have the opportunity to see these patterns, because they do follow the same schedule, day after day, on their way to their job or their school. But some of us have irregular routines, and any, most of us don’t pay any attention. If you slow down, and pay attention, you’ll see the patterns.
But sometimes the pattern involves uniqueness – i.e. strange and unusual people or events that seem to happen only once. But I have to keep reminding myself that my visits have lasted only two weeks; if I was here for a month, or a full season, or perhaps an entire year – then perhaps I would see these strange incidents repeating themselves
5. Another theme – which I did not anticipate, but was delighted to see – was the pervasive sense of affection and caring between and among everyone on the street. Mostly it was apparent in the interactions between parents and children; but sometimes it was between dog-owners and the dogs they were walking; sometimes it was between friends who happened to be walking along together; and sometimes it was between complete strangers and me, as the strangers would smile and nod and say “hello” if they noticed I was watching them. It was a great experience.
Hovering like a flying saucer, M104 or The Sombrero Galaxy, is an amazing looking galaxy and its classic nearly edge on shape helps to remind us that the Universe is deffinitely in 3D.

The Sombrero Galaxy is a peculiar galaxy of unclear classification. It sits at a distant of 31 million light-years away from Earth and is about 105 000 light years in diameter.
It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its outer disk, which from Earth is viewed almost edge-on. The dark dust lane and the bulge give it the appearance of a sombrero hat.
This image was shot in the summer of 2024. For some reason, I overlooked this data completely and had never processed it until now. There's not a lot of integration time, but it's still enough to show some detail in this rather odd looking galaxy.

M104, also known as the Sombrero Galaxy, looks like a flat disk with a soft halo of stars inside. The brown band of dust in the foreground of the disk is particularly striking.
This is about as close as one can get to a human visible light image. You'd never see it this bright with your own eyes, but if you could, it'd look about like this. I increased the saturation a fair amount to make it easier to see the colors, but most people will probably say it's not very colorful at all, which is fair enough.

Explanation:
Residing about 31 million light-years away in the constellation Virgo, Messier 104, more famously known as the Sombrero Galaxy, is one of the most striking edge-on spiral galaxies in the sky. Its prominent dust lane slicing through a glowing halo of stars creates the unmistakable appearance of a wide-brimmed hat drifting through the cosmos.
Despite its relatively small apparent size, the Sombrero Galaxy is a heavyweight in more ways than one. It spans roughly 50,000 light-years across and boasts a central bulge that shines with the luminosity of nearly 800 billion suns. At its heart lies a supermassive black hole with a mass a billion times that of our Sun, making it one of the most massive black holes ever detected in a nearby galaxy.
Its unusual blend of features - both spiral and elliptical - has puzzled astronomers for decades. The Sombrero challenges traditional galaxy classifications and continues to be studied for clues into galactic evolution and structure. Floating in solitude, with few close companions, M104 offers a glimpse into the quiet elegance of the universe. A luminous relic from the early cosmos, wearing its dust lane like a cosmic sash.

This is our version, via our artificial intelligence model, of the image weic2427a provided by Esa Webb about Sombrero Galaxy (also known NGC 4594 or Messier Object 104 or M104). James Webb Space Telescope recently imaged the Sombrero galaxy with its MIRI (Mid-Infrared Instrument), resolving the clumpy nature of the dust along the galaxy’s outer ring.
The mid-infrared light highlights the gas and dust that are part of star formation taking place among the Sombrero galaxy’s outer disk. The rings of the Sombrero galaxy produce less than one solar mass of stars per year, in comparison to the Milky Way’s roughly two solar masses a year. It’s not a particular hotbed of star formation.
The Sombrero galaxy is around 30 million light-years from Earth in the constellation Virgo. The image was made public on November 25, 2024 at 16:00 UTC.

A 12.2 hr LRGB rendition of the famous edge-on galaxy featuring a broad ring of obscuring dust lanes seen in silhouette against an extensive central bulge of stars. My ground-based DSW Chile 150mm-aperture data (or at least my processing of it) has only blurred details of the dust lanes in the overwhelming glare of M104's bright central bulge. About 50,000 light-years across and 28 million light-years away, M104 is one of the largest galaxies at the southern edge of the Virgo Galaxy Cluster. Also known as NGC 4594, the Sombrero galaxy contains a central supermassive black hole [excerpted from APOD 2019 write-up, Wikipedia].

Two productive nights at the Astronomical Society of Victoria's dark sky site out of Heathcote. Skies were clear and still and the Milky Way was fabulous after midnight. I've imaged The Sombrero in the past, but have gained much experience since the last imaging, so I decided to image it again. I'm pleased I did!
Located in an attractive field of colourful (Milky Way) stars, the Sombrero Galaxy (M104, NGC 4594) is a substantial object about 30 million light years away. Seen close to edge on, its highly structured dust lane, very bright core and huge halo of unresolved reddish-yellow stars are key features. The core is believed to contain a supermassive black hole having a mass of about 1 billion solar masses.
The equipment performed very well and I am delighted to have resolved details in the dust lane and structures on the disk.

Named the Sombrero Galaxy for its hat like resemblance, M104 features a prominent dust lane, a brilliant white core and a very bright halo of stars. Within the center of this galaxy lies a massive black hole. This galaxy is estimated to be 50,000 light years across and 28 million light years from earth. It is also moving away from us faster than most other celestial objects at the rate of 1000km/sec.

"With an apparent magnitude of 8, the Sombrero galaxy is beyond the limit of naked-eye visibility but can be spotted through small telescopes most easily during May. M104 is located 28 million light-years away in the constellation Virgo, and with a mass equal to 800 billion suns, it is one of the most massive objects in the Virgo galaxy cluster". Source: nasa.gov

The M1074 Joint Assault Bridge System (JABS) is an armored military engineering vehicle based on the Abrams M1A1 main battle tank. The M1074 was designed by Leonardo DRS Technologies to provide deployable bridge capability for units engaged in military operations.
From my experiences, the scissor bridge designs were more buildable in the brick form comparing to the horizontal bridge laying desgins as seen in the M104 Wolverine or the German's Leguan tank.

The Sombrero lies about 28 million light years away in the constellation of Virgo. It is an unbarred spiral galaxy seen nearly edge on. Among nearby galaxies, it is likely that it has one of the most massive black holes at its core - with a mass of approximately 1 billion times the mass of our sun.
This deep image begins to show the large extent of the halo of stars that surround the galaxy. Recent observations show that this halo is indicative of a giant eliptical galaxy.

Well, after a few months of no builds, I finally got around to making something. And I am damn proud of it. Thanks to several people for all their input which definitely made this rifle so much better. Clearly inspired by the STA-52 assault rifle from Killzone 2, and Dethklaus' STA-52 based shotgun.

These two images were taken using a planetary camera while I was testing guiding settings for my set-up. Both images are the full field of view of the ZWO ASI 174MM Cool camera I normally use for lunar and planetary work. Each image is around 150x20seconds of luminance sub-frames taken at f/10 through my 14inch SCT. By picking a target low to the South then an overhead target I was able to get a much better idea on guiding settings for my main scope.
It was a only by sheer luck (and a lot of patience!) that any result was possible. There was gusting wind most of the night and at this magnification each gust was difficult to guide out without affecting the image.

The thin, dark disk of dust around the galaxy shows up very nicely.
33 x 1-minute at ISO 6400 (taken 14 April 2020) and 8 x 3-minutes at ISO 1600 (taken 8 May 2018). Modified EOS 600D & Revelation 12" Newtonian f/4 reflector telescope.
Frames registered and stacked in DeepSkyStacker software; curves adjusted in Canon Photo Professional; noise reduction in CyberLink PhotoDirector.
Note that I've cropped the result quite extensively, as I'd framed the galaxy very differently in the 2020 and 2018 exposures, so the edges were very uneven.
The Sombrero Galaxy (M104, NGC 4594) is a spiral galaxy about 30 Mly from Earth. It is estimated to contain 100 billion stars and is 25,000 ly in diameter. This color image is processed from LRGB images taken from the CHI-1 El Sauce Observatory in Chile.

Messier Object 104 is a galaxy that is about 1/3 the size of our own galaxy and 29 million light-years away. It's been dubbed "The Sombrero Galaxy" because of its love of guacamole.
I really love the structure of this galaxy! It's pretty small in my scope... I had to crop the image a bit for this result and I don't know that it'd make a great print, but I still smile at how it looks. The galaxy is roughly magnitude 8 and in the region of Virgo and Corvus.
This image came from 3-hours of RGB-data, 1 hour in each color. Individual exposures were 3 minutes long. I'm actually encountering some new astrophotography issues right now, involving the cooling of my camera, and this is limiting some of my results currently. I do plan to keep persevering even if my issues will limit me in some ways.
