M104 is a galaxy in the Virgo constellation, around 31 million light years from earth.
Because of its relative proximity and orientation towards us, it’s a popular target among astronomers. The eye catching feature is of course the dust ring surrounding the core of the galaxy. Most of the galaxy’s hydrogen gas is located within that ring, meaning that it’s also where all the good stuff (star formation and interaction) is happening.

Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 31 million light-years (9.5 Mpc) from Earth. The galaxy has a diameter of approximately 50,000 light-years, 30% 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.
Our beautiful universe.
Messier 104, the Sombrero galaxy some 29 million light years away. Heavy as 800 million suns, and a black hole in the centre.
About 10 hours of data from June 2021 using the TelescopeLive Planewave CDK24 in Chile.
Some clear sky on the night of 23-24 April meant I was able to image, for the first time, the beautiful Sombrero Galaxy in the constellation borders of Virgo and Corvus.
This system is very low in the sky for me. It just clears the rooftops and I lost many exposures as the galaxy drifted down "colliding" with bright orange street lighting...!!! Areas of cloud drifting into view put paid to a few more......:-(
I am pretty happy with the result obtained from the remaining viable exposures.
The Sombrero Galaxy, Messier 104 (NGC 4594), lies at a distance of just over 31 million Lyrs. The galaxy is around 49,000 Lyrs in diameter. It was discovered by Pierre Méchain in 1781.
The most striking feature is the large, dark, dust lane that crosses in front of the galaxy's unusually large bulge. It is this lane and large bulge combination which gives the impression of a Mexican Sombrero hat......The galaxy also has a bright nucleus.

Messier 104 a.k.a. Sombrero Galaxy
…………………………..
Discovered 250 years ago, the Sombrero galaxy (The Hat) is an elliptical galaxy located just over 30 million light-years from us and can be seen between the constellation Virgo and the constellation Corvus. According to measurements made by specialists in the field, M104 has a diameter of about 40,000 light-years, being about 3 times smaller than our galaxy. The name of the Hat is given both by the angle from which we can see it, and due to that prominent ring of cosmic dust that surrounds this galaxy and which is also the main source of new star formation. Regarding the nucleus of this galaxy, with the help of special infrared measurements it was found that in the galactic center of M104 there is a massive black hole, larger than in any other galaxy located within a radius of 40 million light years around the Milky Way.

I was hoping to get this a bit earlier in the year, but the weather cooperated during the night of 2022-06-20. The elliptical galaxy M104 (NGC 4594) is about 30 million light years away in the southern part of the constellation Virgo. It is an unusual elliptical in that it has a prominent broad dust ring. The galaxy has a high surface brightness, which allows me to shoot it from my light polluted backyard in Long Beach.

This famous galaxy in Virgo has a characteristic yellow hue from the many old stars in its gigantic spherical halo and the large amount of dust in the disc of the galaxy, which causes interstellar reddening. The disc of the galaxy has a detailed, thick and obscuring dust lane and is seen almost edge on from our vantage point, some 50 Million light years away. The galaxy gets its quirky name from its resemblance to the brim of the venerable Mexican hat.

This is M104 (Messier Object 104). Also known as NGC 4594 ( New General Catalog 4594). But, because the prominent dust lane and the central bulge give it the appearance of a hat, it is more commonly known as the Sombrero Galaxy.
It is about 31 million light years from our galaxy and about 49,000 light years in diameter.
It is visible with a good pair of bioculars, but as little more than a faint smudge really. A telescope would give you a better view ... but a set of aligned images, stacked and processed, will be better still.
This galaxy is sort of located between the constelllations Virgo (Latin for Virgin) and Corvus (Latin for Crow). If you have a planetarium program like Stellarium or Starry Night on your computer, you can easily check out where it is located and when it will rise into view for your location.
I've processed a set of stacked images using PixInsight and the Nik Collection plugin for Photoshop ... but it definitely needs further work. I just don't have the time right now to fool around with it anymore, so I decided to upload it as it is.
This is a 42 min exposure on the Sombrero Galaxy taken through an 8" scope from my driveway. It was fairly windy the night I took this and ended up having to throw away half the frames I took bc of elongated stars and such. So at some point I will collect more sub exposures to add to this which should help tone down the noise which this image is saturated with. I am thrilled with all the other detail visible in the image and by how the galaxy came out though. Stay tuned!

Sky conditions during the night of 5th/6th March were not the best with patchy annoying cloud but I managed to get a little bit of data on M104 The Sombrero Galaxy.
This data was added to that obtained 2 years ago to produce this image.
It is a difficult target for me being never well placed - close to roofs etc! The Sombrero Galaxy, M104 and also catalogued as NGC 4594, lies at a distance of over 31 million light-years. It is situated on the border between the constellations of Corvus and Virgo.
The galaxy has a somewhat beautiful ethereal appearance with an unusually large light bulge and a strikingly dark dust lane passing in front. This dust lane in conjunction with the bright bulge gives the impression of a Mexican Sombrero - hence the name!
Imaged with an Esprit 120ED and a ZWO 2600MC camera. A total of 4hrs 48min exposure. Calibrated with temp. matched darks. I used flat and dark flat frames.
Many thanks for looking!

I've been dying to get this with my Celestron C8 since acquiring the Celestron Starsense Autoguider system. Quite happy with the result! I love side-on and almost-side on galaxies look - for some reason it shows off their vastness to me.
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.
M104 was discovered in 1781 by the French astronomer and comet hunter Pierre Méchain, one of Charles Messier’s colleagues.

Getting the detail to shine while maintaining the famous characteristic glowing brightness of the central bulge and showing some colour variation... is always pretty tricky with this galaxy.

This would have to be an object on many astrophotographers bucket list. I remember looking back at some textbooks from my university days and seeing M104. Sure it was black and white, but it was so very cool. Skip ahead in time, now, very modest instruments allow us to present incredible renditions of this and many other amazing objects.
This is where imagination takes hold and things become skewed. I know this is all wrong, but when I look at this object it almost appears like a very bright light source is held captive, surrounded by large chunks of matter blocking its light and casting shadows into space. Yep, imagination can certainly conger up fascinating stuff. But slowly, reality takes over and you that there is no way that rocks that large are patrolling the outskirts of this wonderful galaxy ;p
The Sombrero Galaxy has an incredible halo extending well beyond the frame of the image. It has to my eye, a slightly brownish tint to it. Several galaxies further away can be seen through the halo, but they are very small and this is where a large instrument with a serious image scale would be a wonderful treat.
The Sombrero Galaxy, Messier 104, NGC 4594 is a lenticular galaxy found in the constellation Virgo. It’s about a third of the size of our galaxy sporting an unusually large central bulge. One of the most striking features is the prominent dust lane in its inclined disk. This feature resembles a sombrero hat. The dust lane is a symmetrical ring that encloses the bulge of the galaxy. Where it crosses in front of the bulge, we can see the brightness of the galaxy extinguish, and the dark belt is revealed. The ring might also contain most of the cold matter in the Sombrero Galaxy.
At the core, it is believed that one of the most massive black holes measured in any nearby galaxies resides.
Some astronomers consider this galaxy to have the highest absolute magnitude within a radius of 10 megaparsecs of the Milky Way. Visually, this allows a simple set of binoculars to be used allowing the observer to just reveal its presence. Moving up in aperture, a 200 mm will allow you to distinguish the bulge from the disk. From there, 250-300 mm will reveal the dark lane.
Of course, photographically every changes. This image was obtained using a modest 250 mm instrument, and monochromatic camera. If you had eyes the size of dinner plates and didn’t blink for a day, your friends might think you look like a freak, but hey, could you see it? There’s that imagination again…. Apologies.

The incredible glare emitted by the Sombrero Galaxy, catalogued as M104 or NGC4549, lights space for many thousands of light years beyond its central core. This galaxy lies in the constellation of Virgo, being some 31 million light years distant from Earth. This galaxy is approximately one quarter to one third the size of our own Milky Way Galaxy [M104: approximately 50,000 light years diameter].
This galaxy also has a striking dust lane that heavily contrasts against the bright glow. Rolf Olsen has previously defined in his excellent annotated image summary of M104 that the Sombrero Galaxy has a large number of orbiting globular clusters, estimated to be in the number of 1,200 to 2,000. These globular clusters are a spherical collection of a massive number of stars held tightly in formation by gravity.
Hope you enjoy this beautiful galaxy - thank you for looking.

Such a cool galaxy, and SMALL!
I photographed this one last week using the Sky-Watcher Esprit 150 (1050mm focal length) on the EQ8.
A few more lessons learned on this one, the big one being optimizing exposure times depending on target/filter.
I shot 7-minute LUM exposures - which were not ideal. Next time around I'll shoot shorter subs and try to rack up a lot more.

M104 is a galaxy in the constellation Virgo estimated at a distance of 31 million light years. It has a diameter of 49,000 light years, about 1/3 the size of our Milky Way galaxy. It was discovered by the Spitzer Space Telescope that the prominent dust ring in this galaxy is much larger and more massive than thought previously making it more likely that this is a giant elliptical galaxy and not a spiral.

The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is a peculiar galaxy of unclear classification in the constellation borders of Virgo and Corvus, being about 9.55 megaparsecs (31.1 million light-years) from the Milky Way galaxy. It is a member of the Virgo II Groups, a series of galaxies and galaxy clusters strung out from the southern edge of the Virgo Supercluster. It has an isophotal diameter of approximately 29.09 to 32.32 kiloparsecs (94,900 to 105,000 light-years), making it slightly bigger in size than the Milky Way.
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 (thus the name). Astronomers initially thought the halo was small and light, indicative of a spiral galaxy; but the Spitzer Space Telescope found that the halo was significantly larger and more massive than previously thought, indicative of a giant elliptical galaxy.
The galaxy has an apparent magnitude of +8.0, making it easily visible with amateur telescopes, and is considered by some authors to be the galaxy with the highest absolute magnitude within a radius of 10 megaparsecs of the Milky Way. Its large bulge, central supermassive black hole, and dust lane all attract the attention of professional astronomers.
As noted above, this galaxy's most striking feature is the dust lane that crosses in front of the bulge of the galaxy. This dust lane is actually a symmetrical ring that encloses the bulge of the galaxy. Most of the cold atomic hydrogen gas and the dust lie within this ring. The ring might also contain most of the Sombrero Galaxy's cold molecular gas, although this is an inference based on observations with low resolution and weak detections. Additional observations are needed to confirm that the Sombrero galaxy's molecular gas is constrained to the ring. Based on infrared spectroscopy, the dust ring is the primary site of star formation within this galaxy.
The nucleus of the Sombrero Galaxy is classified as a low-ionization nuclear emission-line region (LINER). These are nuclear regions where ionized gas is present, but the ions are only weakly ionized (i.e. the atoms are missing relatively few electrons). The source of energy for ionizing the gas in LINERs has been debated extensively. Some LINER nuclei may be powered by hot, young stars found in star formation regions, whereas other LINER nuclei may be powered by active galactic nuclei (highly energetic regions that contain supermassive black holes). Infrared spectroscopy observations have demonstrated that the nucleus of the Sombrero Galaxy is probably devoid of any significant star formation activity. However, a supermassive black hole has been identified in the nucleus (as discussed in the subsection below), so this active galactic nucleus is probably the energy source that weakly ionizes the gas in the Sombrero Galaxy.

The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) is an unbarred spiral galaxy in the constellation Virgo located 28 million light-years (8.6 Mpc) from Earth. The galaxy has a diameter of approximately 50,000 light-years, 30% 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. Astronomers initially thought that the halo was small and light, indicative of a spiral galaxy, but Spitzer found that the halo around the Sombrero Galaxy is larger and more massive than previously thought, indicative of a giant elliptical galaxy. The galaxy has an apparent magnitude of +9.0, making it easily visible with amateur telescopes, and it is considered by some authors to be the brightest galaxy within a radius of 10 megaparsecs of the Milky Way. The large bulge, the central supermassive black hole, and the dust lane all attract the attention of professional astronomers.

The wonderful Sombrero Galaxy that I processed in HDR to reveal a maximum of details
Exposure time : about 1h30 for each LRGB layer
I've been wanting to get back to M104 for several years. This image was captured with the QSI 683 camera during March.
RGB are 20 x 3 min, binned 2 x 2. Luminance is 25 x 5 min binned 1 x 1.
The Sombrero Galaxy (also known as Messier Object 104, M104 or NGC 4594) 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 31,000,000 light years away with an apparent magnitude of 8.3.
