A starless SHO image of M16, again I did not acquired the data just processed the raw subs. I removed the stars to push the data.
Processed in PixIsight 1.8.8.6.
La galassia a spirale M61 (abbreviazione di Messier 61) si trova a 60 milioni di anni luce e con il suo diametro di circa 100.000 anni luce (simile a quello della Via Lattea) è uno dei più grandi membri dell'ammasso di galassie visibile nella costellazione della Vergine.
Particolarità di questa galassia è la struttura dei suoi bracci: essi mostrano diversi improvvisi cambi di direzione, dando quindi a M61 un aspetto quasi poligonale.
Nell'immagine sono visibile altre due galassie brillanti: NGC 4301 in alto a destra e NGC 4292 (in basso a destra): ma guardando bene, parecchie altre remote galassie sono visibili sullo sfondo.

The spiral galaxy M61 (short for Messier 61) is located 60 million light-years away and with its diameter of about 100,000 light-years (similar to that of the Milky Way) is one of the largest members of the cluster of galaxies visible in the constellation of Virgo.
A peculiarity of this galaxy is the structure of its arms: they show several sudden changes in direction, thus giving M61 an almost polygonal appearance.
In the image, two other bright galaxies are visible: NGC 4301 at the top right and NGC 4292 (at the bottom right): but looking carefully, several other remote galaxies are visible in the background.

This sparkling jumble is Messier 5 — a globular cluster consisting of hundreds of thousands of stars bound together by their collective gravity.
But Messier 5 is no normal globular cluster. At 13 billion years old it dates back to close to the beginning of the Universe, which is some 13.8 billion years of age. It is also one of the biggest clusters known, and at only 24 500 light-years away, it is no wonder that Messier 5 is a popular site for astronomers to train their telescopes on.
Messier 5 also presents a puzzle. Stars in globular clusters grow old and wise together. So Messier 5 should, by now, consist of old, low-mass red giants and other ancient stars. But it is actually teeming with young blue stars known as blue stragglers. These stars spring to life when stars collide, or rip material from one another.

The start with the new mount is done. All went very very well and all was working perfectly :-)
This is the Messier 101 (The Pinwheel Galaxy).
The Pinwheel Galaxy (also known as Messier 101, M101 or NGC 5457) is a face-on spiral galaxy 21 million light-years (6.4 megaparsecs)[5] away from Earth in the constellation Ursa Major. It was discovered by Pierre Méchain in 1781[a] and was communicated that year to Charles Messier, who verified its position for inclusion in the Messier Catalogue as one of its final entries.
On February 28, 2006, NASA and the European Space Agency released a very detailed image of the Pinwheel Galaxy, which was the largest and most-detailed image of a galaxy by Hubble Space Telescope at the time.[10] The image was composed of 51 individual exposures, plus some extra ground-based photos.

Messier 106
▼ Vixen VC200L | Canon EOS R(a) '25
astrocamp.eu/en/messier-106-march-25/
On March 25, I photographed Messier 106, a spiral galaxy about 23.7 million light-years away in Canes Venatici. This was my first successful single-galaxy capture of the season, confirming the precise collimation of my Vixen VC200L astrograph.
Using a Canon EOS R(a) at ISO 1600, I took 40 exposures (300s each) on March 5 from Koblenz, Germany, with calibration frames applied. The final image revealed numerous background galaxies, including NGC 4231, NGC 4232, and NGC 4248, highlighting the vastness of the cosmos.
Messier 8 and 20, the Lagoon and Trifid, appear so low in the northern sky that it has been a challenge for me to image them from home, where trees impinge on my horizon. This was captured at a Westchester Amateur Astronomers' star party last week. The Lagoon is a large emission nebula formed principally from hydrogen gas; the smaller trifid is a more complex structure featuring an emission nebula (red), a reflection nebula (blue) and a dark nebula which carves the red structure into its three petaled shape. Both structures are estimated to lie some 4-6,000 light years from earth.
Tech Stuff: Borg 55FL astrograph/ZWO ASI 1600 MC/IDAS LPS-V4 filter. 24 minutes X 4 second unguided exposures captured in SharpCap livestacks with dark and flat frame correction. SQM-L readings 20.4 (Bortle 5). Processed with PixInsight, Topaz AI Denoise, ACDSee Gemstone 12.
Ive added to some images taken back in 2017 so that this is 54 x 10 minute subexposures of Messier 51 in Canes Venatici.
Im planning to take some RGB and hydrogen alpha to produce a colour image so this is really very much a preliminary post.
Taken with iTelescope T7 from Nerpio in Spain. The larger Messier 51 is interacting gravitationally with smaller NGC 5195.
A rich spiral pattern of dark dust clouds reaches deep into the galactic core where a Seyfert 2 active galactic nucleus is located - a dust ring obscures the central accretion disk and supermassive black hole from view.
A small edge on spiral galaxy IC 4277 is seen beneath NGC 5195 and a bright bar-like irregular galaxy, IC 4278 lies a third of the way along the bottom left.

The arrangement of the spiral arms in the galaxy Messier 63, seen here in an image from the NASA/ESA Hubble Space Telescope, recall the pattern at the center of a sunflower. So the nickname for this cosmic object — the Sunflower Galaxy — is no coincidence.
Discovered by Pierre Mechain in 1779, the galaxy later made it as the 63rd entry into fellow French astronomer Charles Messier’s famous catalogue, published in 1781. The two astronomers spotted the Sunflower Galaxy’s glow in the small, northern constellation Canes Venatici (the Hunting Dogs). We now know this galaxy is about 27 million light-years away and belongs to the M51 Group — a group of galaxies, named after its brightest member, Messier 51, another spiral-shaped galaxy dubbed the Whirlpool Galaxy.
Galactic arms, sunflowers and whirlpools are only a few examples of nature’s apparent preference for spirals. For galaxies like Messier 63 the winding arms shine bright because of the presence of recently formed, blue–white giant stars and clusters, readily seen in this Hubble image.

Messier 20 - 21 (English Below)
Região rica em nebulosidade de emissão, Trífida significa dividida em três lóbulos, logo podemos entender o motivo para esse nome.
Descoberta por Charles Messier em 1764 essa nebulosa combina praticamente todos os tipos de nebulosidade de objetos de céu profundo.
A parte vermelha é a nebulosa de emissão, a parte azul é uma nebulosa de reflexão, a parte escura no centro da nebulosa principal que apresenta o formato Trifurcado é uma nebulosa escura (Bernard 85), além de um aglomerado estelar aberto, no centro da nebulosa. (não confundir com Messier 21 que está no mesmo campo dessa imagem.)
Encontra-se a aproximadamente 5200 anos-luz de distância da terra e encontrasse na constelação de Sagitarius, próxima ao centro galáctico.
Devido a limitação dos equipamentos amadores, é muito difícil capturar alguns detalhes que as vezes acabam passando desapercebidos nas nossas imagens, porém, nessa captura eu consegui o êxito de capturar as duas “anteninhas” no centro da nebulosa. Esse objeto em forma de dois “dedos” são pilares de poeira e gás que podem formar novas estrelas. Cada um desses pilares possui cerca de três quartos de ano-luz e está sendo corroído pela ação da radiação da estrela massiva que os circunda. Outro fato interessante, é que esses pilares foram descoberto apenas em 1999 quando o telescópio espacial Hubble fotografou esse objeto.
No topo esquerdo da imagem se encontra o aglomerado estelar aberto Messier 21 que tem cerca de 4,6 milhões de anos de idade e encontrasse a cerca de 4250 anos-luz da Terra.
Messier 20 - 21
Region rich in emission cloudiness, Trifid means divided into three lobes, so we can understand the reason for this name.
Discovered by Charles Messier in 1764 this nebula combines virtually all types of deep-sky object cloudiness.
The red part is the emission nebula, the blue part is a reflection nebula, the dark part in the center of the main Nebula that has the Trifurcated shape is a dark nebula (Bernard 85), and an open star cluster in the center of the Nebula. (Do not confuse with Messier 21 which is in the same field as this image.)
It is approximately 5200 light years away from the earth and found in the constellation Sagitarius near the galactic center.
Due to the limitation of amateur equipment, it is very difficult to capture some details that sometimes go unnoticed in our images, but in this capture I succeeded in capturing the two "antennas" in the center of the nebula. This two-fingered object is a pillar of dust and gas that can form new stars. Each of these pillars is about three-quarters of a light-year old and is being eroded by the radiation of the massive star surrounding them. Another interesting fact is that these pillars were discovered only in 1999 when the Hubble Space Telescope photographed this object.
At the top left of the image is the open star cluster Messier 21, which is about 4.6 million years old and about 4250 light-years from Earth.

In astronomy, the Pleiades (/ˈplaɪ.ədiːz/ or /ˈpliː.ədiːz/), or Seven Sisters (Messier 45 or M45), is an open star cluster containing middle-aged hot B-type stars located in the constellation of Taurus. It is among the nearest star clusters to Earth and is the cluster most obvious to the naked eye in the night sky. The celestial entity has several meanings in different cultures and traditions.
The cluster is dominated by hot blue and extremely luminous stars that have formed within the last 100 million years. Dust that forms a faint reflection nebulosity around the brightest stars was thought at first to be left over from the formation of the cluster (hence the alternative name Maia Nebula after the star Maia), but is now known to be an unrelated dust cloud in the interstellar medium, through which the stars are currently passing. Computer simulations have shown that the Pleiades was probably formed from a compact configuration that resembled the Orion Nebula.[7] Astronomers estimate that the cluster will survive for about another 250 million years, after which it will disperse due to gravitational interactions with its galactic neighborhood.[8]

J2000 RA 19h 59m 36.340s Dec +22° 43′ 16.09″
M27 / NGC 6853 is a planetary nebula in Vulpecula, at a distance of about 1,360 light years. The central star, a pre-white dwarf, is estimated to have a radius which is 0.055±0.02 R☉ which gives it a size larger than any other known white dwarf. The central star mass was estimated in 1999 by Napiwotzki to be 0.56±0.01 M☉.
This object was the first planetary nebula to be discovered by Charles Messier in 1764. it is easily visible in binoculars and small telescopes.
