Leo Triplet
Explanation: A mere 30 million light-years away, large spiral galaxy NGC 3628 (center left) shares its neighborhood in the local Universe with two other large spirals, in a magnificent grouping otherwise known as the Leo Triplet. In fact, fellow trio member M65 is near the center right edge of this deep cosmic group portrait, with M66 just above it and to the left. But, perhaps most intriguing is the spectacular tail stretching down for about 300,000 light-years from NGC 3628's warped, edge-on disk. Known as a tidal tail, the structure has been drawn out of the galaxy by gravitational tides during brief but violent past interactions with its large neighbors. Not often imaged so distinctly, the tidal tail is composed of young bluish star clusters and star-forming regions.

NGC 3628, also known as the Hamburger Galaxy or Sarah's Galaxy, is an unbarred spiral galaxy about 35 million light-years away in the constellation Leo. It was discovered by William Herschel in 1784. It has an approximately 300,000 light-years long tidal tail. Along with M65 and M66, NGC 3628 forms the Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, effectively transecting the galaxy to the view from Earth.
Due to the presence of an x-shaped bulge, visible in multiple wavelengths, it has been argued that NGC 3628 is instead a barred spiral galaxy with the bar seen end-on. Simulations have shown that bars often form in disk galaxies during interactions and mergers, and NGC 3628 is known to be interacting with its two large neighbors.Ngc 3628 Hamburger

Last quick pass of the night. A trio of galaxies... M65, M66, and NGC3628. Just an hour of data.... needs about 3-4 hours.
NGC3628 is also known as the Hamburger Galaxy and is located in the constellation of Leo about 35 million light years away. Along with M65 and M66 it forms a part of the famous Leo Triplet. It is about 100,000 light years across and has a faint tidal tail about 300,000 light years long, a small portion of which can be seen starting from the upper left corner of the galaxy and extending to the left edge of the screen. it has a prominent dust lane bisecting the main body of the galaxy.

Leo Triplet M66-M65-NGC3628 - Galaxies - Constellation Leo The Leo Triplet is composed of the spiral galaxies M66, M65 and NGC3628, they are in interaction with each other and a neutral hydrogen halo connects them, a sign of a close encounter that took place 800 million years ago. The triplet is about 35 million light years from us and is located in the constellation Leo. M66 the largest and brightest of the complex is also known as NGC3627 was discovered by Pierre Méchain in 1780. Quite easy to locate halfway between the stars θ Leonis and ι Leonis. In order to appreciate some of its details, it is necessary to have a telescope with an aperture of at least 150mm. Visible from both hemispheres, the best period for its observation is between February and August. M65 also known as NGC3623 was discovered by Pierre Méchain in 1780 at the same time as M66, Charles Messier described it as a very faint and starless nebula. 22 million light years away from us, it is estimated to have a diameter of about 70,000 light years and a mass equal to 85 billion solar masses. NGC3628 third component of the triplet is less luminous than the others, but very extensive, crossed in its length by a long luminous band, it is about 35 million light years from us, it was discovered in 1784 by William Herschel.

I tested my new Optolong L Pro filter 77 mm with 70-200/2,8 lens. This photo is only 1 shot - 300 s taken by Nikon Z7, f 2,8, ISO 1600, cropped 15x, FOV 2,7 x 1,8 ang.deg. I could not take more shots because bad weather. I think the result is not bad. Next time I will take more shots including darks, bias and flats. Precessed in Adobe PS + Astronomic tools. Taken on April 22, 2020.
Imaged during the night of the 3-4 March this is an image of the galaxy triplet in the constellation of Leo.
Two of the galaxies were catalogued by Charles Messier, M66 (top left) and M65 (bottom left). The third galaxy (right) is found in the NGC Catalogue as NGC 3628.
NGC 3628 is popularly known as the "Hamburger Galaxy" due to its edge on appearance to us said to resemble a Hamburger.....!
Lying at a distance of 35 million light-years from us they are a true group of interacting systems.
Our viewpoint means we see the three galaxies at different angles. NGC appears edge-on - displaying lots of dust and a prominent dust lane.
M65 & M66 are inclined enough so that their spiral arms are visible.
The three systems are very different in character.
M66 is a barred and shows a high rate of star formation with numerous tell-tale red/pink areas of glowing hydrogen gas. Its spiral arms are also deformed, indicative of interactive gravitational forces within the group.
M65 is an intermediate spiral and is poor in dust and star formation. It appears the least affected by interaction showing a more or less classical spiral shape.
NGC3628 is an unbarred spiral which we see edge on. The galaxy is transacted by a broad band of dust which stretches along its outer edge hiding young stars in the galaxy arms.

2026 Leo Triplet -galaxies M65 M66 NGC3628 with SC_C8+0.63X + ASI533MC-P
Il periodo dell'anno Febbraio-Maggio è chiamato per noi amanti del cielo la "Stagione delle Galassie" poichè è il periodo migliore per osservarle e/o fotografarle.
Questi oggetti del cielo sono generalmente apparentemente piccoli di dimensioni, solo a causa della loro enorme distanza, quindi è preferibile fotografarli con focali medio-lunghe; perciò mi sono nuovamente messo in gioco utilizzando un setup strumentale ai limiti della tolleranza.
A volte le galassie si trovano in gruppi ravvicinati anche se solo prospetticamente. E' il caso del famoso "Tripletto del Leone", formato da 3 galassie molto belle: "M65", "M66" e "NGC3628". Con il mio setup ho dovuto realizzare un mosaico di 2 pannelli e in quasti casi tutto si complica anche a causa dell'Inquinamento Luminoso e delle condizioni meteo non sempre uguali tra le sessioni fotografiche.
Eppure malgrado le difficoltà oggettive ho cercato di raggiungere un dicreto e gradevole risultato e penso di esserci riuscito.
_____________
The period from February to May is known to us sky lovers as "Galaxy Season" because it's the best time to observe and/or photograph them.
These celestial objects are generally seemingly small in size, simply because of their enormous distance, so it's best to photograph them with medium-long focal lengths; so I once again ventured into the unknown, using an instrumental setup at the limits of my capabilities.
Sometimes galaxies are found in close-knit groups, even if only in perspective. This is the case of the famous Leo Triplet, made up of three very beautiful galaxies: "M65", "M66" and "NGC3628". With my setup, I had to create a mosaic of two panels, and in these cases everything gets complicated, also due to light pollution and weather conditions that are not always the same between photographic sessions.
Yet despite the objective difficulties I tried to achieve a decent and pleasant result and I think I succeeded.

I took this during a rare period of consecutive clear nights and was imaged after finishing off the Christmas Tree nebula. This was taken over 2 nights. The conditions were clear but the rather unstable atmosphere made guiding difficult. Though the galaxies are fine I’m not happy with the stars.
OBJECT DESCRIPTIONS:-
M65, M 66 & NGC3628 are part off the Leo Triplet. These Galaxies Lie approximately between 31 & 35 million ly from earth.
M65 is believed to have very little star formation going on and the number of old stars compered to new ones is quit high. It has a visual magnitude of 10.25.
M66 is believed to have had a interaction with NGC3628 in the past resulting in a very high central mass. There have been 5 supernovae observed between 1973 & 2018. It has a visual magnitude of 8.9.
NGC3628 also known as the Hamburger Galaxy. it is a unbarred spiral galaxy with a visual magnitude of 10.2.

Situé à environ 35 millions d’années-lumière dans la constellation du Lion, le Triplet du Lion est un petit ensemble de galaxies en interaction gravitationnelle. Il est composé de trois galaxies spirales : M65, M66 et NGC 3628.
M65 et M66 (en bas de l’image) présentent des structures spirales relativement classiques, tandis que NGC 3628 se distingue par une vue par la tranche, marquée par une large bande de poussière sombre qui traverse son disque.
Cependant, cet aspect esthétique masque une histoire dynamique et agitée. Ces galaxies ne sont pas isolées : leurs formes actuelles portent les traces d’interactions gravitationnelles passées. En particulier, M66 et NGC 3628 se seraient rapprochées il y a environ 800 millions d’années, perturbant profondément leur structure interne. Ces interactions ont entraîné des redistributions de gaz et probablement déclenché des épisodes intenses de formation d’étoiles.
Il en résulte une longue traînée qui s’échappe de NGC 3628. S’étendant sur près de 300 000 années-lumière vers le haut et la gauche de l’image. Elle s’est formée lorsque les forces de marée ont arraché de la matière à la galaxie.

-------
Located about 35 million light-years away in the constellation Leo, the Leo Triplet is a small group of galaxies in gravitational interaction. It is composed of three spiral galaxies: M65, M66, and NGC 3628.
M65 and M66 (at the bottom of the image) display relatively classic spiral structures, while NGC 3628 stands out due to its edge-on view, marked by a wide dark dust lane crossing its disk.
However, this striking appearance masks a dynamic and turbulent history. These galaxies are not isolated: their current shapes bear the traces of past gravitational interactions. In particular, M66 and NGC 3628 are believed to have come close about 800 million years ago, deeply disturbing their internal structures. These interactions led to the redistribution of gas and likely triggered intense episodes of star formation.
As a result, a long tidal tail extends from NGC 3628, stretching nearly 300,000 light-years toward the upper left of the image. It formed when tidal forces pulled material away from the galaxy.

A first attempt at the well-known triangle of galaxies known as the Leo Triplet.
On the top, NGC3628 aka the Hamburger galaxy; below, M66 and M65.
I'm particularly pleased to have got 3 extra bonus galaxies in the frame: right up in the top-left the tiny fuzzy IC2782, with IC2776 just below and IC2763 in the middle of the left edge of the frame.
Nearly two hours' data, Altair 26C at gain 100 with Neodymium filter, 3-minute subs, and plenty darks+flats+bias calibrations as well.

NGC3628 è una galassia a spirale facente parte del famoso tripletto del Leone nella costellazione che porta lo stesso nome. Le sue compagne ben più visibili sono la m65 e m66.
E' stata scoperta da William Herschel nel lontano 1784 e la sua caratteristica più evidente è la notevole fascia oscura causata dalla polvere disposta lungo la parte esterna della spirale.
La galassia ha una distanza stimata di circa 38 milioni di anni luce basandosi sul redshift z del catalogo NED di 0.002812.

The Hamburger Galaxy, not my best image as it's quite low in the northern sky from my location and I was exposing while shooting over house roofs which, no doubt, caused thermal currents and destabilised the star and object light.
NGC 3628 is a unbarred spiral galaxy, located about 35 million light-years away in the constellation Leo.
Along with M65 and M66, NGC 3628 forms the Leo Triplet, a small group of galaxies. Its most conspicuous feature is the broad and obscuring band of dust located along the outer edge of its spiral arms, roughly resembling meat between bread rolls and giving it the nickname "The Hamburger Galaxy".
This image was exposed across two nights, 3 & 4 April 2022, using a QHY268M through a Celestron C8" SCT at the native 2032mm focal length, tracked on a Hypertuned CGEM mount.
Total exposure time was 6 hours and 23 minutes through all LRGB filters.
