Data for this image was taken with a 1m (1m0-04) telescope at CTIO (Cerro Tololo, Chile) operated by the Las Cumbres Observatory Global Telescope (LCOGT) Network. The Principal Investigator for this data set was BJ Fulton.
For this image I used publicly available data from the LCOGT Science Archive. The following filters were used:
SDSS I' for Red, V for Green and B for Blue.
This galaxy lies at a distance of about 28 million light years. Also in the image are numerous smaller galaxies including what looks like a pair of interacting galaxies just off the left and a little above M104's disk.
M104 is located in the constellation of Virgo.

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 galaxy has a diameter of approximately 50,000 light-years), a third of the size of the Milky Way.
It has a bright nucleus, an unusually large central bulge, and a prominent dust lane in its inclined disk.
The dark dust lane and the bulge give this galaxy the appearance of a sombrero.
Imaged using a 8" SCT (at the native 2032mm focal length), with a QHY268M camera on a hypertuned CGEM mount.
The total exposure time of this image for all of the LRGB filters was 6 hours and 14 minutes.

The Sombrero Galaxy, also known as M104, is another iconic Hubble telescope image. Astronomers named it Sombrero because it resembles the well-known wide-brimmed Mexican hat with a tall bulge at the center. The galaxy is 50,000 light-years wide and is roughly 29 million light-years away, close enough to be spotted with amateur telescopes. Researchers have found evidence of a super-massive black hole at the center of the Sombrero Galaxy. Estimated to be as large as a billion Suns, it's one of the heftiest black holes in the neighboring universe.

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 capture some photons a few nights a year. The Sombrero Galaxy is about 50,000,000 light years away with an apparent magnitude of 8.3.

The Sombrero Galaxy is a lenticular galaxy in the constellation Virgo and is approximately 31.1 million light-years from Earth. The galaxy has a diameter of approximately 49,000 light-years which is about 30% the size of our own Milky Way.
This is the 3rd image I processed from HST data this past weekend. Here's M104, also known as the Sombrero Galaxy. Despite being too tiny for my telescopes, this is one of my favorite galaxies. Can you blame me? The nearly edge-on angle of this, otherwise rather flat galaxy really gives a perspective that is really unique.
Definitely better at full screen, and hopefully FB won't mess up with the image too much. Hope you like it!
Messier 104, or NGC 4594, is also known as the Sombrero Galaxy. When you look at it, you can certainly understand why. I remember first seeing this in an astronomy textbook back in the 80s. It was a black-and-white photo, but it was so cool. That book is still on my bookshelf. However, revisiting that image is impressive in many ways. First, it stirs my interest in the universe and all its treasures. It reminds me that we have come such a long way in a relatively short time frame. With very modest equipment, amateurs can produce such beautiful renditions of these stellar objects.
The Sombrero Galaxy is an unbarred spiral galaxy located in the Virgo constellation. It’s very bright, with an apparent magnitude of 9.98 and is 29.3 light years from us. You can see this object from a dark location with a simple pair of binoculars. A larger instrument around a 10 to 12-inch scope will reveal the dark dust lane.
That dark dust lane crosses in front of the galaxy, forming a symmetrical ring around the bulge. The ring contains most of the cold hydrogen gas and dust of Messier 104, and is the primary site of starburst activity in this galaxy.
The galaxy is receding from us at an incredible speed of 1024 km/s. The American astronomer Vesto Slipher first measured the recession velocity at the Lowell Observatory in 1912. It was the largest redshift ever measured in a galaxy at that time.
When I first combined the data to create a colour component of the image using separate Red, Green, and Blue filters, it was striking how red/brown this area is. The halo is massive and extends away from the galaxy for some distance. But it definitely has a dirty brown look about it. That dirty brown was something I wanted to retain and convey in this rendition. My other goal was to try and reveal any structure within the massive halo, if possible. Performing an initial stretch of the raw data, the galaxy is hidden in an enormous ball of light. There is little to see of the galaxy itself other than that signature bold dark symmetrical ring. Fortunately, many image-processing software packages exist that can help us look further into the great ball of light and reveal just a little more structure. The final goal what to present and preserve that massive halo, to have that through the eyepiece feel about it. Highlighting the bright halo slowly decaying only to blend into space while still revealing the inner features of the galaxy.
Hopefully, the object retains a natural appearance. With any luck, I hope it looks like you rolled down the window in your space cruiser and took a happy snap of a galaxy through the portal. I think that would be the greatest compliment any astrophotographer could receive. The final image is a crop from a full frame, as the target is not that large in a small scope. If you look carefully, one or two tiny galaxies may be hidden within the glow. The Sombrero Galaxy’s vast halo may extend for 10,000 light years beyond the spiral structure.

Since I have had no time nor good weather for taking new images, I've found this one that was originally discarded for the little star drift due to wind gusts. Anyway I re-think myself about and I decided it was not too bad so I go for and this is the results:
M104 sombrero galaxy taken during last year Winter Star Party with an Officina Stellare RiLA 16" f3.8 on a Paramount ME using a FLI Microline 11002 with FLI filterwheel and Astrodon genII LRGB Filters. Guided Via a Sbig STV on a MiniBorg refractor. I've also managed to include more data from an old image set of this subject taken witha Vixen RSS200 f4 telescope. This is the central crop 1:1 res. Even with the slight drift the details on the galaxy disc are still quite remarkable. Exposure time is about 120:60:60:60

Hi Folks,
My second imaging project of the year has now been posted on my website.
Messier 104 - The Sombrero Galaxy - 1.7 Hrs in LRGB - Too Little Time, Too Low in the Sky, Too Much Smoke…
Messier 104, better known as the Sombrero Galaxy, is a lenticular galaxy located 29 Million light-years away in the constellation of Virgo.
This target is a favorite from when I was a kid!
Unfortunately, it is a challenging target for me as it is positioned very low in my skies and falls in a narrow gap between two tree lines that only gives me a maximum of two hours of exposure a night. I have never been able to image it before, as the weather in the past prevented it.
This year, I am getting a late start on my imaging, and I was determined to try and image it.
At this point, it was already at the zenith when astronomical darkness rolled in, and I would only get about an hour of exposure each evening. The moon would soon become a problem, so I only had a few days to grab it. On top of all that, we have had the smoke from the tragic Alberta Wildfires in our skies. The Jet stream brought the bulk of the smoke to the south of us for a few days, and I decided to image through the thin smoke we still had.
So - to summarize: I would likely have short integrations (Too little Time), I would be imaging at a low angle, looking through a lot of atmosphere ( Too Low in the Sky), and I would be looking through smoke (Too Much Smoke...)
So what could go wrong - right?
I ended up getting only 1.7 hours of LRGB integration - and with the smoke, I knew the image would come out poorly.
But you always need to have that "first" image so that you can come back and create a better one so you can show everyone how your skills have grown - right?
I processed the image as best I could, and it came out.... well.... OK.
Not great by any means - but to be honest, better than I expected. I credit the amazing camera I used (ASI2600MM-Pro) and the amazing tools now available in Pixinsight!
So please enjoy my mediocre Messier 104 shot!
The full story behind this project, as well as a step-by-step processing walkthrough, can be seen here:
cosgrovescosmos.com/projects/m104
I'm not sure when I will next be able to capture photons. In addition to the Alberta Wildfires, we are now getting smoke from wildfires in Quebec! This smoke is so thick and low that everything looks yellow and foggy. We can even smell this smoke plume. Tragically, it seems like all of Canada is ablaze right now and their smoke decided to park in our skies. I sure hope things improve soon!
Thanks for looking!
Clear Skies,
Pat

This image is a test image of "Sombrero nebula" (M104) taken at my home as well.
The light intensity is much less than that of the M42, and so the detailed part is contaminated with background of the city light.
Next time, I will try to go to hills or mountains to get a darker surroundings. :)
M104 or The Sombrero Galaxy is a spiral galaxy in the constellation borders of Virgo and Corvus. The Sombrero Galaxy is about 29.35 million light years from our galaxy. Looking at this photo of M104 it really illustrates the vastness of space. If you look closely at the background, you can see a few faint galaxies off in the distance (cigar-like and circular objects).
Thanks for viewing and clear skies everyone!

What started off as a quick hour and a half acquisition of data turned into a 7+ hour project. Initially collected the RGB as binned 2x2, with 300sec exposures but changed my mind part way through and only collected binned 1x1 (600sec exposures). Luminance was also captured using 600sec exposures. I’m still learning the ins and outs of astrophotography made a few mistakes along the way but I’m pretty happy with the result.

The Sombrero Galaxy, one of the more unusual-looking spiral galaxies, owes its name to its resemblance to the Mexican hat of the same name. It has a large central bulge and a bright nucleus, and its spiral arms pass through a thick dust lane, which is the ring encircling the central bulge. The galaxy’s appearance is due to our seeing it “edge on”. The Sombrero Galaxy is classed an an unbarred spiral galaxy and can be found in the constellation of Virgo. Its estimated distance from Earth is 29 million light years. As many as 2000 globular clusters swarm around the core of the Sombrero Galaxy, and the number could be related to the size of the central bulge. M 104 was a challenging target from my location with a maximum altitude of 30°

Messier 104 is known as the "Sombrero" galaxy. It is a spiral galaxy in the constellation Virgo, whose bright nucleus, nusually large central bulge, and prominent dust ring give it the appearance of a Mexican hat.

A really bright galaxy core with a huge bulge of light to both sides of the nucleus making it a really different type of galaxy to image. Lot's of red shift in the image gives it an almost muddy brown appearance.

Barred spiral galaxy NGC 4731 lies some 65 million light-years away in the large Virgo cluster of galaxies, not too far away from the more famous M104 Sombrero galaxy. Its broad spiral arms are distorted by gravitational interaction with a fellow Virgo cluster member, a giant elliptical galaxy called NGC 4697 [which is outside of the field of view]. NGC 4731 is well over 100,000 light-years across [but only 6.6´ X 4.2´ in apparent size, with a visual magnitude: 11.5], with a smaller deformed neighbour to the top right called NGC 4731A.
The galaxy itself has a few star forming regions denoted by the small pink hotspots, with a mottled surrounding background coloured by possibly thousands of tiny galaxies perhaps hundreds of times more distant.
This area was definitely a challenge to complete. Thank you for having a look.
Bye! 😊

Comment: For some reason this large data set was consistently not so great in quality; something like average or less quality seeing? Even after so many hours of sub-exposures, the data wasn’t robust and became quite noisy.

The Sombrero Galaxy (also known as M104 or NGC 4594) is a peculiar galaxy with stunning features - a bright nucleus enshrouded by an enormous central bulge and a striking dust ring. Viewing from an almost edge-on angle, the galaxy looks like a shining sombrero floating in space.
The dust ring is highly symmetrical and contains most of the galaxy's cold molecular gas. Some hypothesize that an elliptical galaxy collided with a disk galaxy billions of years ago, creating this jaw-dropping maverick.
Sombrero is a member of "Virgo II Groups", a band of more than 100 galactic clusters and individual galaxies stretching across the night sky. Many galaxies can be found in this image hiding among the stars: some are spiral, some are elliptical, and most are millions of light-years away.

The main galaxy here is gets its nickname due to the resemblance to M104, the Sombrero Galaxy. We are seeing this spiral galaxy edge-on. The stripe down the center are clouds of dust within the spiral arms. This is pretty much the same thing we see when we look into our milky way, just at an enormous scale because we are in the middle of it. The Little Sombrero is 40 million light years away.
There are at least a couple larger galaxies that can be seen here. But, in the dark shadows there are hundreds of visible smudges. This field is absolutely littered with distant galaxies. They appear dim and tiny to us, but each is home to billions of stars.
This image consists of 5.2 hours of exposure taken over a couple of nights.
Each image captured with 15 x 5 seconds of live stacking, cropped to 18 x 24 arc-minutes, and enlarged 450%.
NGC 4565 is a similar size to our own Milky Way galaxy – perhaps slightly smaller – and probably resembles it edge-on too. With a slender dust lane cutting through the nucleus, it bears a similarity to M104, the Sombrero Galaxy.
This exposure was 83 minutes, terminated only because the frame quality of this northerly target was reducing as it sank to 20° above the horizon.

The Sombrero galaxy is a very small world, 30% the size of our Milky Way. It lies about 30 million light years away from our home, which is actually not that far. The Sombrero holds the biggest supermassive black hole every recorded in any nearby galaxy. This also impacts its brightness, as it is the brightest galaxy in a 10 megaparsec radius of the Milky Way!
We spent a little more than 3 hours on it. We did 3 minute exposures instead of our usual 6, because of how small and bright it is.
You can see how we captured this target in Episode 6 of Galactic Hunter!
