Whirlpool Galaxy M51

The Whirlpool Galaxy, also known as Messier 51a, M51a, and NGC 5194, is an interacting grand-design spiral galaxy with a Seyfert 2 active galactic nucleus.It lies in the constellation Canes Venatici, and was the first galaxy to be classified as a spiral galaxy. Its distance is estimated to be 23 million light-years away from Earth.

NGC 6822 Barnard's Galaxy

NGC 6822 (also known as Barnard's Galaxy, IC 4895, or Caldwell 57) is a barred irregular galaxy approximately 1.6 million light-years away in the constellation Sagittarius. Part of the Local Group of galaxies, it was discovered by E. E. Barnard in 1884. It is one of the closer galaxies to the Milky Way. It is similar in structure and composition to the Small Magellanic Cloud. It is about 7,000 light-years in diameter.The galaxy contains regions of rich star formation and curious nebulae, such as the bubble visible in this image. Astronomers classify NGC 6822 as an irregular dwarf galaxy because of its odd shape and relatively diminutive size by galactic standards. The strange shapes of these cosmic misfits help researchers understand how galaxies interact, evolve and occasionally "cannibalise" each other, leaving behind radiant, star-filled scraps.

At only about a tenth of the Milky Way's size, Barnard’s Galaxy fits contains about 10 million stars — a far cry from the Milky Way’s estimated 400 billion.

Ο NGC 6822 ή Γαλαξίας του Μπάρναρντ, είναι ακανόνιστος γαλαξίας που βρίσκεται περίπου 1,6 εκατομμύριο έτη φωτός μακριά, στον αστερισμό Τοξότη. Είναι μέλος της Τοπικής ομάδας γαλαξιών και ανακαλύφθηκε από τον Αμερικανό αστρονόμο E.E. Μπάρναρντ το 1884. Είναι ένας από τους κοντινότερους γαλαξίες, παρόμοιος σε δομή και σύσταση με το Μικρό Νέφος του Μαγγελάνου. Οι διαστάσεις του είναι περίπου 7000 έτη φωτός.

Messier 106

Messier 106 (also known as NGC 4258) is an intermediate spiral galaxy in the constellation Canes Venatici. It was discovered by Pierre Méchain in 1781. M106 is at a distance of about 22 to 25 million light-years away from Earth. It is also a Seyfert II galaxy. Due to x-rays and unusual emission lines detected, it is suspected that part of the galaxy is falling into a supermassive black hole in the center. NGC 4217 is a possible companion galaxy of Messier 106. A Type II supernova was observed in this galaxy in May 2014.

M63 Sunflower Galaxy

M63 was discovered by Pierre Méchain on June 14, 1779.[4] The galaxy was then listed by Charles Messier as object 63 in the Messier Catalogue.

In the mid-19th century, Lord Rosse identified spiral structures within the galaxy, making this one of the first galaxies in which such structure was identified.[4]

In 1971, a supernova with a magnitude of 11.8 appeared in one of the arms of M63.

Triangulum Galaxy M33 I love it !!!

This is an image with the same old data from Nov 2013 but with a new approach about processing .
I made a synthetic luminance layer from the whole of my frames. Then I apply about 30 iterations of selective deconvolution in ccdstack. With ''selective'' i mean: manual selection of the area for deconvolution.
And the question is :What is the exposure time in this image ?
the total exposure time is the sum of whole frames and that is or the sum of the separate master layers such as Lum LumSynth RedSynth(Red+Ha) and so on

M33: Triangulum Galaxy

    M33 reprocessed with Registax Wavelets          

    

      Early version                                                                                            

The Triangulum Galaxy is a spiral galaxy approximately 3 million light years (ly) from Earth in the constellation Triangulum. It is catalogued as Messier 33 or NGC 598.

With a diameter of about 50,000 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. (See below.) Triangulum may be home to 40 billion stars, compared to 400 billion for the Milky Way, and 1 trillion (1000 billion) stars for Andromeda.[6]
As mentioned above, M33 is linked to M31 by several streams of neutral hydrogen[47] and stars,[47] which suggests that a past interaction between these two galaxies took place between 2-8 billion years ago,[48][49] and a more violent encounter will occur 2.5 billion years in the future.[47]

The fate of the Triangulum Galaxy is unclear, but seems to be linked to its larger neighbor the Andromeda Galaxy. Suggested future scenarios for M33 include being torn apart and absorbed by Andromeda, fueling the latter with hydrogen to form new stars; eventually exhausting all of its gas, and thus the ability to form new stars;[50] or participating in the collision between the Milky Way and M31, most likely ending up orbiting the merger product of the latter two galaxies and fusing with it much later. Two other possibilities are a collision with the Milky Way before Andromeda arrives or an ejection out of the Local Group.[51]

M33 Triangulum Galaxy in pure Ha light

M33 Triangulum Galaxy in pure Ha light

Using infrared observations from the Spitzer Space Telescope, a total of 515 discrete candidate sources of 24 μm emission within the Triangulum galaxy have been catalogued as of 2007. The brightest sources lie within the central region of the galaxy and along the spiral arms.

Many of the emission sources are associated with HII regions of star formation.[39] The four brightest HII regions are designated NGC 588, NGC 592, NGC 595 and NGC 604. These regions are associated with molecular clouds containing(1.2–4) × 105 solar masses. The brightest of these regions, NGC 604, may have undergone a discrete outburst of star formation about three million years ago.[40] This nebula is the second most luminous HII region within the Local Group of galaxies, at (4.5 ± 1.5) × 107 times the luminosity of the Sun.[37] Other prominent HII regions in Triangulum include IC 132, IC 133 and IK 53.[36]

The northern main spiral arm contains four large HII regions, while the southern arm has greater concentrations of young, hot stars.[36] The estimated rate of supernova explosions in the Triangulum Galaxy is 0.06 Type Ia and 0.62 Type Ib/Type II per century. This is equivalent to a supernova explosion every 147 years, on average.[41] As of 2008, a total of 100 supernova remnants have been identified in the Triangulum Galaxy,[42] and a majority of the remnants lie in the southern half of the spiral galaxy. Similar asymmetries exist for H I and H II regions, plus highly luminous concentrations of massive, O type stars. The center of the distribution of these features is offset about two arc minutes to the southwest.[36] Being a local galaxy, theCentral Bureau for Astronomical Telegrams (CBAT) tracks novae in M33 along with M31 and M81.[43]

NGC 7331 and Stephan's quintet

                                       

The spiral galaxy NGC 7331, in Pegasus, can be seen with small telescopes under dark skies as a faint fuzzy spot. It is an island universe similar to our own Galaxy (or maybe somewhat larger) and placed at a distance of 50 million light-years. NGC 7331 was discovered by Wilhelm Herschel in 1784

Stephan's Quintet in the constellation Pegasus is the first identified compact galaxy group of five galaxies about 300 million light-years away. The group was discovered by Édouard Stephan in 1877 at Marseilles Observatory. The group is the most studied of all the compact galaxy groups.

Recent infrared observations made with NASA's Spitzer Space Telescope have revealed the presence of a huge intergalactic shock wave, or "sonic boom" in the middle of Stephan's Quintet. This discovery, made by an international research team including scientists from the Max Planck Institute for Nuclear Physics (MPIK) in Heidelberg, provides a local view of what might have been going on in the early universe, when vast mergers and collisions between galaxies were commonplace.

NGC 4565 is an edge-on unbarred spiral galaxy about 30 million light-years away in the constellation Coma Berenices.
The 10th magnitude galaxy sits perpendicular to our own Milky Way galaxy.
It is also known as the Needle Galaxy for its narrow profile.First spotted in 1785 by Uranus' discoverer, Sir William Herschel (1738-1822), this is one of the most famous examples of an edge-on spiral galaxy.

Pinwheel Galaxy M101

 

The Pinwheel Galaxy (also known as Messier 101 or NGC 5457) is a face-on spiral galaxy about 27 million light-years away in the constellation Ursa Major.
It was discovered by Pierre Méchain on March 27, 1781, and he subsequently communicated his discovery to Charles Messier who verified its position and added it to the Messier Catalogue as one of the final entries.
M101 is a relatively large galaxy compared to the Milky Way. With a diameter of 170,000 light-years it is nearly twice the size of the Milky Way. It has a disk mass on the order of 100 billion solar masses, along with a small bulge of about 3 billion solar masses.
