On my last nightscape photography trip to Taralga, Australia, I was able to get some shots of the Milky Way’s core region not long before it set over the southwestern horizon. Once that favoured area of the heavens was–literally–out of the picture, I turned my attention to photographing some of the other galaxies that are visible here in the Southern Hemisphere.
I recently posted one of those images, containing the Large and Small Magellanic Clouds, which are dwarf galaxies travelling through space with our own Milky Way galaxy. As well as those relatively-close massive collections of stars, planets, dust, gas and asteroids–and the odd black hole or two–there are a few other “islands universes” that are visible to naked-eye observers. I photographed two of these, the Andromeda Galaxy and the Triangulum Galaxy, as they hung low in the northern sky.
Known in astronomical catalogues as “M31”, the Andromeda Galaxy sits around 2.5 million light-years from our position in the “Local Group” of galaxies. M31 is visible in my photo as a fuzzy-yet-distinct bright disc mid-way down the shot, and about one third in from the left. If you look up to the right, in the one o’clock direction from Andromeda, there’s a much smaller blur of light showing the position of the Triangulum Galaxy. Aka “M33”, this galaxy is nearly 3 million light-years away in space. The Milky Way, M31 and M33 are the three largest galaxies, respectively, in the Local Group.
This image was stacked from ten single-frame photos, each of which I shot with my Canon EOS 6D Mk II camera, a Yongnuo 50mm f/1.4 lens @ f/1.4, using an exposure time of 8 seconds @ ISO 6400.

Triangulum (Messier 33)
(J2000) RA: 01h 33m 50.02s Dec: +30° 39′ 36.7″
Messier 33 is a low-luminosity flocculent spiral galaxy at 3 million light-years in Triangulum. It is catalogued also as NGC 598 and known as Triangulum Galaxy. The galaxy is the smallest spiral galaxy in the Local Group and it is believed to be a big satellite of the Andromeda Galaxy.
M33 has two asymmetric faint arms, and an interstellar medium rich in gaseous filaments that extends for about 7 kpc. Although the inner disk is relatively undisturbed, the northern arm is less regular in shape than the southern one. M33, is a bulge-free galaxy with only two optically luminous dwarf galaxies believed to be its satellites: AndXXII (McConnachie et al., 2009; Martin et al., 2016) and Pisces VII (Martínez-Delgado et al., 2022) m discovered by me in 2020. However, given its mass, ΛCDM cosmological simulations predict that M33 should host a larger number of satellites, at least 10.
The neutral hydrogen (HI) disk is three times larger than the star-forming disk and is clearly warped. The outer disk has the same inclination as the inner one with respect to our line of sight but the position angle of the major axis changes by about 30 degrees compared to the inner disk and is more aligned with the M31 direction. While M33's undisturbed inner disk indicates that no major collisions between M31 and M33 or between M33 and a satellite have occurred in the past, the distortion could be the result of a flyby about 9 billion years ago. Timing assessments make this scenario unlikely and favor the hypothesis of a first fall of M33 in the region of influence of M31.
Northern hemisphere folk have been enjoying a celestial show over the past week or more, in the form of a naked-eye-visible comet. The celestial sojourner has a name that is, per astronomical good-practice, totally unromantic and very clinical. "Comet C/2020 F3 NEOWISE" — or just NEOWISE for short, is what's written on its name tag. The name came from the NASA mission that discovered it, also called NEOWISE, for Near-Earth Object Wide-field Infrared Survey Explorer. You can hit up Google–or your favourite search engine–to find thousands of photos of this beautiful addition to the northern summer's skies.
OK, that Public Service Announcement out of the way, I can now go on to tell you about my less-exciting-than-a-comet photo. The image features the Milky Way's neighbouring galaxy M31, aka the "Andromeda Galaxy". I need to explain that the word "neighbouring" has a different scale about it in the realm of astronomy. M31 is around 2.5 million light-years from our home planet and is one of the most distant objects that mere mortals can see with our unaided eyes. That's not the kind of neighbour to whom you can pay a quick visit to borrow some tools or a cup of sugar, but in the scale of things in the universe, it's nearby.
My photo was created by taking two shots of the same scene, which I then processed through what is known as "stacking" software to reduce the digital noise in the image and try to enhance the details of the distant galaxy.
I took the two images using my Canon EOS 6D Mk II camera, a Yongnuo 50mm f/1.4 lens @ f/1.8, using an exposure time of 6.0 seconds @ ISO 3200. The software used to make the final stacked image is called "Starry Landscape Stacker".
Triangulum Galaxy (M33, NGC 598). The last time we imaged this galaxy was 3 years ago and I wanted to add more data, however a hard drive failure meant the old data was lost. This session was the first since August and also the first since upgrading the computer to an SSD and 16 GB of RAM which made a big improvement to its performance. It was a beautifully clear night with no moon and great visibility.
[From Wikipedia]The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC (New General Catalogue) 598. With the D25 isophotal diameter of 61,100 light-years, the Triangulum Galaxy is the third-largest member of the Local Group of galaxies, behind the Andromeda Galaxy and the Milky Way.
The galaxy is the smallest spiral galaxy in the Local Group, and is believed to be a satellite of the Andromeda Galaxy or on its rebound into the latter due to their interactions, velocities, and proximity to one another in the night sky. Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion stars for Andromeda Galaxy.

It may seem like I've given up on landscape photography around here but I have not! Life's been busy this year... Astrophotography, fortunately, I can do from my back yard and it's accomplished at night so it's a bit easier to fit in. Unfortunately I'm going to lose this soon too as Oregon slips into its gray winter...
Anyway, this is a shot of Messier 33 (aka The Triangulum Galaxy). It's a relatively close neighbor to our Milky Way Galaxy (about the same distance as the famous Andromeda Galaxy though this one is quite a bit smaller). The neat thing about these close galaxies is that it's relatively easy to start to resolve their constituent stars. Although, until photography was applied to astronomy, astronomers believed that the strange 'spiral nebulae' in the heavens were clouds of gas. We now know that each of these amazingly beautiful systems are actually made up of billions of stars... Blows my mind almost every time I think of it.
You can see more than just stars in this one. The pink 'blobs' in the photo are emission nebulae in M33. The large nebula in the lower left (NGC 604) is so bright it's often easier to spot than the galaxy itself!

I spent a few days up in a cabin in the Tafjord mountains where I finally got a shot of the Panstarrs comet, together with the Northern lights. This was taken at Pyttbua cabin which sits at 1161 metres above sea level and far from any civilisation which means very little light pollution. The Aurora wasn´t very strong, barely visible to the naked eye but very clear on the picture, capturing the comet was all just luck.
Another point of interest is the Andromeda galaxy above the comet. This is the closest spiral galaxy to us (but not the closest galaxy) at 2.5 million light years from the earth. It is estimated to contain one trillion stars and is expected to collide with our own galaxy in 4.5 billion years, so make a note in your diary.
To the right of the comet above the central chimney of the cabin is the spiral Triangulum Galaxy which is estimated to be 2.38 to 3.07 million light years away and home to 40 billion stars.
Halfway between Andromeda and Triangulum galaxy is Mirach or Beta Andromedae. This is a red giant and is approximately 100 times the size of our sun. It is approximately 197 light years from the earth.
The highest tagged item is Almach or Gamma Andromedae. This is actually a quadruple star system which is approximately 350 light years from earth.
Looking slightly above and to the right of Andromeda there is a line, this is either a shooting star or a satellite.
Thanks for looking at my photos, comments are much appreciated.

It’s likely that I’ve mentioned in other posts that I love being able to photograph the Andromeda Galaxy, aka the Andromeda Nebula, or M31. In the late 1970s, in my high school days, I fell in love with astronomy and so spent plenty of time in my school’s library, poring over the few astronomy books they had on the shelves. One of the most enthralling objects appearing in the books’ photographic plates was the Andromeda Galaxy. These were long-exposure images of this body of around one trillion stars, about 2.5 million light-years from Earth, captured by some of the largest and most legendary telescopes of the 20th century.
Even though M31 is best seen much further north than my latitude of 34 degrees below the equator, it’s still possible to photograph this little glowing fuzzy blob low over the northern horizon. However, I didn’t use a telescope–big or small–to get this photo. This image is a single-frame photo, captured with a Canon EOS 6D Mk II camera, a Canon 40mm lens @ f/2.8, and a 10-second exposure @ ISO 12800.

It also has an H II nucleus.

Messier 33 galaxy in Triangulum, LHaRGB composite imaged from October 2011 to January 2012.
The project target was to get a better look at the faint ring-shaped hydrogen regions dotting the rim of M33. The data was largely undersampled at 1.75" per pixel and lucky seeing conditions (sub 3" FWHM in Finland is excellent) provided an FWHM of around 1.5 to 2 pixels on most nights, so 2X drizzle-stacking brought out a bit more details and actual resolution. The galaxy was processed with minimal noise reduction as I prefer noise over false details and artefacts caused by (especially anisotropic) noise filters.

The Danjera Dam near Nowra, Australia, is a popular campsite and especially so for freshwater fishing folk. Its seven-kilometre long catchment is stocked with rainbow trout and Australian bass and hosts plenty of eels. Also under the waters of the dam are the ruins of the old mining town of Yalwal, where gold was discovered in 1852. A bushfire in 1939 burnt almost the whole village, leaving only one residence, one shop and the Post Office. Completion of the dam in 1971 drowned the gully and with it the area’s gold-boom history.
I have visited the dam a half-dozen or so times in the past two years, including on an ill-fated trip in early November, when I lost the memory card containing my last Milky Way core shots of the year. There were also several photos of M31, the Andromeda Galaxy, on that memory card, so I had to go back one more time to shoot some more. This time I was very careful to make sure that the memory card made it home with me. As well as M31 there are plenty of stars visible in the sky, and a few reflected off the dam's surface, towards the bottom of the shot.
Here is a photo of M31 in the sky over the dam, which I captured with my Canon EOS 6D Mk II camera, a Yongnuo 50mm f/1.4 lens @ f/1.4, using an exposure time of 8.0 seconds @ ISO 6400.

This Dachstein mountain massif, center of the world heritage region Hallstatt-Dachstein, Austria, is seen under a starry sky. Among the constellations visible in the sky are, from left to right, Canis minor, Canis major (with Sirius, the brightest star in the sky), Orion, Taurus (including the Hyades and Pleiades star clusters), Aries and Andromeda. Our neighbouring galaxies, the Andomeda nebula M31 and the Triangulum galaxy M33, are visible as small, faint smudges at far right.
Some fog, which reflects yellowish light from distant villages, makes the stars at lower altitudes disappear.

Andromeda, like the Milky Way, is a canonical galaxy and a laboratory for examining in detail many of the astrophysical processes that are studied in the more distant field. Studying Andromeda and Triangulum in the Local Group has the advantage of offering us a view free from the problems that plague galactic studies due to our location within the Milky Way, but their location within the Local Group allows us to resolve and study individual stars and infer population properties in incomparably greater detail than is possible in distant systems.
Andromeda is the closest giant spiral galaxy to our own and the only other giant galaxy in the Local Group.
If Andromeda is the twin of the Milky Way, the Triangulum Galaxy (M33), with a mass about 10 times less than either of these two giants, is their little sister. M33 is the third brightest galaxy in the Local Group and probably also a satellite of M31. The relatively undisturbed optical appearance of M33 places strong constraints on the past interaction of these two galaxies, although it should be noted that the gaseous component is highly deformed. To study the halos of both the Andromeda and Triangulum galaxies in more detail, astronomers performed a deep photometric survey. They detected a multitude of large-scale structures of low surface brightness, including several flows and new, rather faint dwarf galaxies.
Significant variations in stellar populations due to flow-like structures are detected in the inner halo. Some previously unseen structures are present in my ultradeep wide-field survey And450.

Recently, I was able to get a EOS 450D, which I modified for astrophotography by removing the original canon LPF2 filter and replacing it by a Baader BCF astro filter. This image is the result of a first test. Unfortunately, due to the unstable weather conditions and the humid air, I was not able to expose as long as I wanted. Furthermore, due to some software issues with autoguiding, the image is not completely flawless.

I've got around 3 hours of imaging over two different days a month apart with my William Optics FLT91, ZWO ASI2600MC Pro and Optolong L-Pro broadband filter. I would like to get more time on it, but nights are getting cloudy again, so uploading "as is" now and will return to it when I get more clear nights. I think it's already looking good after ~3 hours, so can't wait to get more time on it. Maybe use the L-Enhance filter to get more Ha data.

Thanks for looking and clear skies!
I used the high ISO sky exposure from this image together with an averaged stack of the brightest of the cliffs - then lightened them a bit. There is a bit of a purple color cast I think I should work to remove here.. especially in the portions of the image on the right that were not "trucker lit."
Wondering about the Trucker Lit designation... see Truckin ][ or Castled or the original Truckin' for background.

The Triangulum Galaxy (M33). Returning to an old favourite, we thought we'd add the captured data to data taken from a similar session two years ago and see if nearly six and a half hours of exposures improved the image. It does but not as much as I'd hoped although processing the image was easier. I think the resulting image looks a bit more natural than the attempt in 2018.

The Triangulum Galaxy (M33 = NGC 598) is, like the Milky Way, a member of the Local Group of Galaxies. At approximately 2.8 million light years distant, it is close enough that numerous bright star-forming regions can be seen within the galaxy using a modest-sized telescope.

Triangulum Galaxy Extended Halo - And450 survey (sample)
by Giuseppe Donatiello flic.kr/p/2q7MZSG
Triangulum Galaxy (M33) extends well beyond its disk in a radius of some degrees. In this region, excluding the dust cirrus clouds, there is a system of faint stellar streams and debris produced by the tidal destruction of dwarf galaxies.
Such structures are extremely weak, but they can be highlighted with an appropriate treatment of the data (it is not a simple "inverted") that enhances the latent signal.

Photographed with my brand new toy - I had to wait several months for it... the Zwo Seestar S50 Smart Telescope.
After a few rainy days, the first photo of a galaxy:
M33 is a spiral galaxy in the triangle constellation in the northern fixed star sky between the constellations Andromeda and Aries. After the Andromeda Galaxy, it is the second-brightest spiral galaxy in the night sky and one of our galaxy closest.
On the left edge of the photo, the interrupted light trail of satellite(s) is visible (Starlink?).
The photo consists of many individual images, each exposed for 10 seconds over a period of 48 minutes and automatically stacked by the Smart Telescope. This suppresses image noise and reveals more details - the longer the recording time, the clearer the result.
I then edited the resulting photo with Luminar Neo and jpg-Illuminator.

Fotografiert mit meinem brandneuen Spielzeug - ich musste mehrere Monate darauf warten... das ZWO Seestar S50 Smart Teleskop.
Hier ist nach einigen Regentagen das erste Foto mit einer Galaxie:
M33 (Dreiecksgalaxie oder Triangulumgalaxie) ist eine Spiralgalaxie im Sternbild "Dreieck" am nördlichen Fixsternhimmel zwischen den Sternbildern Andromeda und Widder. Sie ist nach dem Andromedanebel die zweithellste Spiralgalaxie am Nachthimmel und eine der unserer Galaxie nächstgelegenen.
Am linken Rand des Fotos ist die unterbrochene Lichtspur eines oder mehrerer Satelliten sichtbar (Starlink?).
Das Foto besteht aus vielen Einzelbildern, die während eines Zeitraums von 48 Minuten jeweils 10 Sekunden belichtet und durch das Smart Telekop automatisch "gestackt" (gestapelt) wurden. Dadurch wird das Bildrauschen unterdrückt und es werden mehr Details sichtbar - je länger die Aufnahmezeit, desto klarer also das Ergebnis. Danach habe ich das so entstandene Foto mit Luminar Neo und jpg-Illuminator etwas nachbearbeitet.

Description of the shooting object:
In the constellation Triangulum there is this magnificent spiral galaxy. With a diameter of more than 50 thousand light years, M33 is the third largest in the Local Group of galaxies after the Andromeda galaxy (M31) and our Milky Way. It contains 40 billion stars, while in our Galaxy, according to various estimates, from 100 to 400 billion. M33 is 3 million light-years from the Milky Way and is likely a satellite of the Andromeda Galaxy.

This portion of the sky stretches roughly overhead for mid-northern latitudes after twilight at the beginning of winter. In the lower left corner are the two closest open star clusters to us -- the Hyades (with Aldebaran in the foreground) and the Pleiades. In the upper right corner are the two other spiral galaxies that are part of our Local Group -- The Andromeda Galaxy (M31) and The Triangulum Galaxy (M33). There are many other star clusters visible, and the California Nebula (NGC 1499) appears above the Pleiades. The plane of the Milky Way stretches from the lower left corner up through the center at the top. There are some dark molecular clouds visible through Taurus, Auriga, and Perseus in that portion of the image. Capella is the star in the upper left corner.
This is a stack of 9 exposures of about 210 s each shot with a Nikon D80 at f/3.5 and ISO 1600. Images were calibrated with dark and bias frames in PixInsight. All processing was done in either PixInsight or PS CS 5.1.

This galaxy is called The Triangulum because it lies in the Triangulum constellation. It's sometimes also called the Pinwheel Galaxy because of its shape.
An augmented color picture of Messier 33, highlighting the hydrogen rich regions in pink. My initial goal was to create an exploratory image of the galaxy and accept the resulting raised noise floor in exchange for better overall visuals on the very faint ring-like Hydrogen emission shapes on the outer edge, especially lower and lower right regions.
The image has been exposed during four nights in October and November, per channel:
Luminance 20 x 10 minutes
Hydrogen alpha 15x20 minutes
Red, Green and Blue 11x10 minutes each
For a total exposure of 13 hrs 50 minutes.
Taken with StarlightXpress SXVR-H18 thru William Optics FLT-110, WO AFR-4, and Baader filters.
Reprocessed data with proper calibration and better workflow for more even transition in the faint Ha regions to background sky.
The most distant object observable with the naked eye, the Triangulum galaxy is 3 million light years away. The red regions mark emission nebulae and show the star forming regions in the galaxy.

While Comet Holmes is quite large (about 1° in width) it is much fainter than it was two months ago. However, Comet Tuttle is returning to the inner solar system. It's about magnitude 6 and just visible in dark skies. In light polluted city skies it is just barely visible. With a four 30-second exposures stacked and 7 dark frames subtracted I was able to tease out the faint green of Comet Tuttle.
On December 30 it will make its way toward the constellation Triangulum and come very close to the Triangulum Galaxy.
With a diameter of about 60,000 light-years, the Triangulum galaxy is the third largest member of the Local Group of galaxies. It may be a gravitationally bound companion of the Andromeda Galaxy. Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion stars for Andromeda. The Triangulum Galaxy is a spiral galaxy approximately 3 million light-years from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598, and is sometimes informally referred to as the Pinwheel Galaxy, a nickname it shares with Messier 101. The Triangulum Galaxy is the third-largest member of the Local Group of galaxies, which includes the Milky Way, the Andromeda Galaxy and about 44 other smaller galaxies. It is one of the most distant permanent objects that can be viewed with the naked eye.
The galaxy is the smallest spiral galaxy in the Local Group and it is believed to be a satellite of the Andromeda Galaxy due to their interactions, velocities and proximity to one another in the night sky.00 billion for the Milky Way, and 1 trillion stars for Andromeda.
The disk of Triangulum has an estimated mass of (3-6) × 109 solar masses, while the gas component is about 3.2 × 109 solar masses. Thus the combined mass of all baryonic matter in the galaxy may be 1010 solar masses. The contribution of the dark matter component out to a radius of 55×103 ly (17 kpc) is equivalent to about 5 × 1010 solar masses.[Wikipedia]

Original caption: NASA's Hubble Space Telescope brings the vastness of space into perspective in this mosaic image of the Triangulum galaxy (M33), our neighbor in a collection of dozens of galaxies called the Local Group.
The unprecedentedly detailed portrait of Triangulum is composed of 54 Hubble fields of view stitched together, revealing nearly 25 million individually resolved stars. The borders of individual Hubble images trace the jagged edge of the mosaic, which spans 19,400 light-years across. Striking areas of star birth glow bright blue throughout the galaxy, particularly in beautiful nebulas of hot, ionized hydrogen gas like star-forming region NGC 604 in the upper left.
Triangulum is oriented with its face toward us, ideal for studying the distribution of stars and gas in its well-defined spiral structure. While astronomers are still delving into the immense trove of data collected by Hubble, a few characteristics stand out immediately, inviting key comparisons and contrasts with our own Milky Way galaxy and the third large spiral in the Local Group, the Andromeda galaxy.
"My first impression on seeing the Hubble images was, wow, that really is a lot of star formation," said astronomer Julianne Dalcanton of the University of Washington in Seattle, who led the project. "The star formation rate intensity is 10 times higher than the area surveyed in the Andromeda galaxy in 2015."
Astronomers think that Triangulum has been an introvert, avoiding disruptive interactions with other galaxies, instead spending the eons tending its well-ordered spiral and turning out new generations of stars. Further research may determine if Triangulum is actually a newer member of the Local Group of galaxies, and perhaps its quiet days will soon be over.
This mosaic was created from images taken by Hubble's Advanced Camera for Surveys between February 2017 and February 2018.
The Hubble Space Telescope is a project of international cooperation between NASA and ESA (European Space Agency). NASA's Goddard Space Flight Center in Greenbelt, Maryland, manages the telescope. The Space Telescope Science Institute (STScI) in Baltimore, Maryland, conducts Hubble science operations. STScI is operated for NASA by the Association of Universities for Research in Astronomy in Washington, D.C.

Much improved from my Canon 40D image of this galaxy from last year. Beyond the better color post-processing and the visibility of the hydrogen alpha regions, the image is sharper and shows far more fine detail. This despite nearly the same integration time (220 minutes vs. 190). The QHY8 really does make a difference.

The Triangulum Galaxy is a spiral galaxy 2.73 million light-years from Earth in the constellation Triangulum. It is known as Messier 33 or NGC 598.
I obtained almost 6 hours of data over three separate sessions with my William Optics FLT91 + 1.0x flattener, ZWO ASI2600MC Pro camera and ZWO AM5 mount.
In the first two sessions I used the Optolong L-Pro broadband filter to get a broader spectrum of light. This resulted in the image here: flic.kr/p/2p2k291
In the last session I used the Optolong L-Ultimate to get narrowband Ha data. I extracted the RGB channels on both broadband and narrowband, and recombined into LRGB in PixInsight using the Red (Ha) channel from the narrowband session. This highlights the Ha/Red parts of this galaxy much more.
