It's hard to lay off of this spring target given the visual drama of the two intersecting galaxies. Here I've used a sensitive monochrome astro-cam to squeeze a lot of detail from a small scope in my suburban yard.

The Andromeda Galaxy, also called Messier 31 or M31, is the nearest major galaxy to the Milky Way.
It is 2.5 million light years away from Earth and is the other major member of the Local Group, our local collection of galaxies.
Like the Milky Way, it is a barred spiral galaxy, so-called for the bar-like structure formed by the stars in its center.
Andromeda is about 260,000 light-years wide, according to NASA, making it the largest galaxy in the Local Group. However, its mass is roughly comparable to or even less than that of the Milky Way, according to NASA JPL
Scientists think the galaxy could be anywhere from 5 and 10 billion years old. However, it may not have existed in its current form until two or three billion years ago, when two smaller galaxies orbiting each other merged to form the current Andromeda Galaxy, according to a 2018 study.

The star of the photo is the famous Whirlpool Galaxy, very bright and peculiar given the proximity of its companion NGC 5195 with which it interacts.
Its long arms are rich in new star formations and emit in the typical wavelength of hydrogen, the parts in red. Recent observations have revealed perpendicular structures of dust from each galactic arm, suggesting new hypotheses about the galaxy's formation and structure.
Distant from us 23 million light years, it is still visible with binoculars or small telescopes.
Of the 14 hours of data collected I then used 6 hours in RGB and 4 hours in Halpha to highlight the active regions of its arms.

My second record of the small (view from Earth) Galaxy NGC 2997 (located in the Constellation of Antlia). In this record (which has a much longer total exposure time compared to the previous record), I was able to better capture some features of the galaxy, but there is still a lot to be done. The stacked frames (captured on 03 consecutive nights) totaled 12 hours and 15 minutes of exposure.
"NGC 2997 is an unbarred spiral galaxy, located about 40 million light years away in the constellation of Antlia. NGC 2997 contains hundreds of billions of stars and is believed to have a mass of about 100 billion times that of our Sun, but probably less massive than our Milky Way. The galaxy is moving away from us at about 1085 kilometers per second ". Source: annesastronomynews.com/

I seriously can't stop taking portraits of my friends and it's become an addiction and I need to stop. Anyways, I'm going to force myself to take an actual fine art photo this week. I don't know why but I can't seem to bring myself to do it and I believe I have artistic depression. I'll see where I go from here.
These 3 galaxies are each of a common different type, and positioned perfectly for a side by side comparison.

A galaxy is a massive, gravitationally bound system consisting of stars, an interstellar medium of gas and dust, and dark matter.[1][2] The name is from the Greek root galaxias [γαλαξίας], meaning "milky," a reference to the Milky Way galaxy. Typical galaxies range from dwarfs with as few as ten million[3] (107) stars up to giants with one trillion[4] (1012) stars, all orbiting a common center of mass. Galaxies can also contain many multiple star systems, star clusters, and various interstellar clouds. The Sun is one of the stars in the Milky Way galaxy; the Solar System includes the Earth and all the other objects that orbit the Sun.
Historically, galaxies have been categorized according to their apparent shape (usually referred to as their visual morphology). A common form is the elliptical galaxy,[5] which has an ellipse-shaped light profile. Spiral galaxies are disk-shaped assemblages with curving, dusty arms. Galaxies with irregular or unusual shapes are known as peculiar galaxies, and typically result from disruption by the gravitational pull of neighboring galaxies. Such interactions between nearby galaxies, which may ultimately result in galaxies merging, may induce episodes of significantly increased star formation, producing what is called a starburst galaxy. Small galaxies that lack a coherent structure could also be referred to as irregular galaxies.[6]
There are probably more than 100 billion (1011) galaxies in the observable universe.[7] Most galaxies are 1,000 to 100,000[4] parsecs in diameter and are usually separated by distances on the order of millions of parsecs (or megaparsecs).[8] Intergalactic space (the space between galaxies) is filled with a tenuous gas of an average density less than one atom per cubic meter. The majority of galaxies are organized into a hierarchy of associations called clusters, which, in turn, can form larger groups called superclusters. These larger structures are generally arranged into sheets and filaments, which surround immense voids in the universe.[9]
Although it is not yet well understood, dark matter appears to account for around 90% of the mass of most galaxies. Observational data suggests that supermassive black holes may exist at the center of many, if not all, galaxies. They are proposed to be the primary cause of active galactic nuclei found at the core of some galaxies. The Milky Way galaxy appears to harbor at least one such object within its nucleus.[10]

Whenever life gets you down, Mrs. Brown,
And things seem hard or tough,
And people are stupid, obnoxious or daft,
And you feel that you've had quite eno-o-o-o-o-ough,
Just remember that you're standing on a planet that's evolving
And revolving at 900 miles an hour.
It's orbiting at 19 miles a second, so it's reckoned,
The sun that is the source of all our power.
Now the sun, and you and me, and all the stars that we can see,
Are moving at a million miles a day,
In the outer spiral arm, at 40, 000 miles an hour,
Of a galaxy we call the Milky Way.
Our galaxy itself contains a hundred billion stars;
It's a hundred thousand light-years side to side;
It bulges in the middle sixteen thousand light-years thick,
But out by us it's just three thousand light-years wide.
We're thirty thousand light-years from Galactic Central Point,
We go 'round every two hundred million years;
And our galaxy itself is one of millions of billions
In this amazing and expanding universe.
Our universe itself keeps on expanding and expanding,
In all of the directions it can whiz;
As fast as it can go, at the speed of light, you know,
Twelve million miles a minute and that's the fastest speed there is.
So remember, when you're feeling very small and insecure,
How amazingly unlikely is your birth;
And pray that there's intelligent life somewhere out in space,
'Cause there's bugger all down here on Earth!
I tried to image both Bode & Cigar galaxies (M81 & M82 respectively) in one frame. These galaxies are about 12 million light years from Earth. They are located in Ursa Major constellation. Bode galaxy is larger than Cigar galaxy, but the later has very strong star bursting ejection from the center of the galaxy.

These three images are of the central region of the magnificent spiral galaxy M100, taken with three generations of the Hubble Space Telescope cameras that were sequentially swapped out aboard the telescope, and document the consistently improving capability of the observatory.
The image on the left was taken with the Wide Field/Planetary Camera 1 in 1993. The photo is blurry due to a manufacturing flaw (called spherical aberration) in Hubble's primary mirror. Celestial images could not be brought into a single focus. [Credit: NASA, ESA, and Judy Schmidt]
The middle image was taken in late 1993 with Wide Field/Planetary Camera 2 that was installed during the Dec. 2-13 space shuttle servicing mission (SM1, STS-61). The camera contained corrective optics to compensate for the mirror flaw, and so the galaxy snapped into sharp focus when photographed. [Credit: NASA, ESA, and J. DePasquale (STScI)]
The image on the right was taken with a newer instrument, Wide Field Camera 3, that was installed on Hubble during the space shuttle Servicing Mission 4 in May 2009. [Credit: NASA, ESA, and Judy Schmidt]
In celebration of the 25th anniversary of NASA's first space servicing mission to Hubble, these comparison photos of one of the telescope's first targets are being released today.

Abell 1413 is part of the Abell catalog, a collection of over 4,000 rich clusters of galaxies fairly close to Earth—at least from a cosmological perspective—their light took less than 3 billion years to reach us. The clusters are called rich due to the huge number of galaxies they play host to. Abell 1413 is observed to contain more than 300 galaxies held together by the immense gravity of the cluster.

At 10th magnitude, the Circinus Dwarf Galaxy, an active galaxy, is a relatively bright object only 14 million light years distant, making it one of the closest galaxies to us, outside the Local Group.
So we should know a lot about it – but we don’t.
It’s quite astonishing that this object’s main claim to fame is that, despite its close proximity, it was not discovered until 1977 – maybe a century or two later than most other comparable galaxies!
This is because its direction is in the plane of the Milky Way and as a consequence it is viewed through a rich Milky Way starfield. It is about 48° from the galactic centre and a mere 3° below the galactic plane.
The sheer number of stars and other material in the galaxy’s disc (possibly combined with its southerly latitude) must have led to it being overlooked.

It’s been nearly a month since my last astro-post. First I switched over to my bigger scope for galaxy season (Celestron 8 inch), then I had all kinds of trouble adjusting to the switch.
Anyway, here is Bode’s Galaxy discovered in 1774 by German astronomer Johann Bode and added to Charles Messier’s catalogue a couple of years later. The galaxy is a large, bright spiral about 11.8 million light years away.
It took many nights to get enough data for this picture because the object doesn’t come up until 10pm at my location, then disappears behind trees ‘round midnight.

This galaxy, along with others in this region, were part of a Webb study by an international team of astronomers, who observed the chemical signature of carbon-rich dust grains at redshift ~7. This is roughly equivalent to one billion years after the birth of the Universe. Similar observational signatures have been observed in the much more recent Universe, attributed to complex, carbon-based molecules known as polycyclic aromatic hydrocarbons (PAHs). It is not thought likely, however, that PAHs would have developed within the first billion years of cosmic time. Therefore, this observation suggests the exciting possibility that Webb may have observed a different species of carbon-based molecule: possibly minuscule graphite- or diamond-like grains produced by the earliest stars or supernovae. This observation suggests exciting avenues of investigation into both the production of cosmic dust and the earliest stellar populations in our Universe, and was made possible by Webb’s unprecedented sensitivity.
The team’s research indicates that this particular galaxy showed significant dust obscuration and has undergone substantial metal enrichment relative to galaxies with similar mass at the same redshift. The team also believes the galaxy's visible colour gradient may indicate a peculiar geometrical alignment of stars and dust.
In this image, blue, green, and red were assigned to Webb’s NIRCam (Near-Infrared Camera) data at 0.9, 1.15, and 1.5 microns; 2.0, 2.77, and 3.55 microns; and 3.56, 4.1, and 4.44 microns (F090W, F115W, and F150W; F200W, F277W, and F335M; and F356W, F410M, and F444W), respectively.
The galaxy is shown zoomed in on a region measuring roughly 1x1 arcseconds, which is a measure of angular distance on the sky. One arcsecond is equal to 1/3600 of one degree of arc (the full Moon has an angular diameter of about 0.5 degrees). The actual size of an object that covers one arcsecond on the sky depends on its distance from the telescope.
