Just over 4 hours' data on the Heart and Soul nebulae in Cassiopaeia with an Optolong l-eNhance filter, processed in AstroPixelProcessor, siril and darktable.
IC 2177 a.k.a. Seagull Nebula.
.....................................................
IC2177 is a region of nebulosity that spans about 240 light-years along the border between the constellations Monoceros and Canis Major, at a distance of about 3,800 light-years from Earth.
This is not the first time I have shot at the same targets with both the color and mono cameras, but it is the first time I have used both data sets for a single image. The color camera data was used as the Luminance channel, along with the Halpha data, and for the final result I used an LRGB approach.

NGC 4565 a.k.a. Needle Galaxy
.....................................................
NGC 4565, better known as the Needle Galaxy, is a spiral galaxy located in the constellation Coma Berenice, at about 40 million light-years from Earth. This galaxy is larger than the Milky Way, with a diameter of 130-150000 light-years, and appears to be brighter than Andromeda. Due to its shape, in addition to Needle, NGC4565 is also known as Flying Saucer Galaxy or Berenice's Hair Clip. Very well known and popular in astrophotography, Needle Galaxy can be imaged with a small telescope, but a longer focal length would lead to a more detailed result.

NGC 7635 a.k.a. Bubble Nebula
……………………………................
Space is full of things / situations / events that intrigue us, NGC7635 being one of those. In short and for everyone to understand, a massive star is caught in a "bubble". This star is almost 50 times larger than the Sun and the emitted radiation is about 1 million times stronger than it, producing a stellar wind that exceeds 5 million km per hour, wind that pushes dust and gas outward creating thus a shell or a bubble, a situation that obviously led to the popular name of this nebula.
As general information, the Bubble Nebula is an emission nebula with a diameter of about 7 light-years, located in the constellation Cassiopeia, at a distance of over 7000 light-years from Earth and it was discovered in 1787 by the British astronomer, William Herschel.
Specialists believe that in a short time ( meaning in the next 10-20 million years), the "guilty" star will consume its energy resources, and will explode, forming a supernova.

IC 5070 a.k.a. Pelican Nebula
…………………………................
This is a nebula emission that can be found at a distance of about 1800 light-years from Earth, in the constellation Cygnus, right next to the North American nebula, being separated from it by a molecular cloud that crosses that region. Pelican Nebula is an area that stands out both for the good environment for the formation of new stars, and also for the gas clouds that are constantly expanding. In other words, Pelican Nebula is in a continuous transformation. due to the ionization caused by the light of the new stars that heats the gas in the area, thus leading to an increase in the volume of these gas clouds.

The "bubble" at the bottom of the image are two nebulae, NGC 6164 and NGC 6165. This bluish, soap bubble-like outer nebulosity is being pushed by the central star, an O7 supergiant, approximately 40 times more massive than our sun. Can you imagine such a thing?

Bonjour tout le monde !
Voici la nébuleuse Trifide (Messier 20).
Le mot « trifide » est un anglicisme provenant du mot « trifid », dont la signification en français pourrait s’apparenter à « trilobé » (3 lobes).
Cette nébuleuse est une combinaison rare de trois types de nébuleuses qui révèlent la frénésie d'étoiles fraichement formées et continuera à produire des étoiles dans le future.
- Nébuleuse à émission : une zone rose voire rougeoyante de formation d’étoiles, où se trouve notamment un jeune système stellaire triple responsable à lui seul de la luminosité de la nébuleuse.
- Nébuleuse à réflexion : une zone gazeuse bleue au Nord de la zone émettrice, légèrement plus ténue que le cœur rougeoyant de la nébuleuse à émission, qui réfléchi d’avantage la partie bleue du spectre de la lumière des étoiles environnantes.
- Nébuleuse obscure : des filaments de poussières interstellaires parcourent la nébuleuse Trifide, lui donnant cet aspect de lobes, laissant penser à la forme d’un trèfle. Ces filaments de poussières, résidus de supernova ou de formation d’étoiles, sont entrés dans un processus de contraction et donneront un jour naissance à de futures jeunes étoiles.
Elle se situe à environ 5500 années lumières de nous.
Elle est visible dans la constellation du sagittaire, en plein coeur de la voie lactée.

Messier 20 a.k.a Trifid Nebula
……………………………………………
Discovered in the 18th century by Charles Messier, the Trifid Nebula has an apparent diameter of about 25 light years, is located a little over 4000 light years from Earth, and can be observed in the Centaurus Arm of the Milky Way, at the edge of the constellation Sagittarius.
What is special about this deep sky object is that M20 is a combination of an open cluster (in the middle of the red area), an emission nebula (red area), a reflection nebula (blue area) and a dark nebula (those gaps in the star field). Unfortunately, this dark nebula does not stand out very well in the attached image because I had less than 3 hours of “photon collection”.

Nun hat auch mir Corona einen Quarantäne-Strich durch die Rechnung gemacht. So konnte ich gestern Abend nicht wie geplant das schöne Wetter für die Sternen-Fotografie nutzen. Zum Glück gibt es da noch über das Internet steuerbare Roboter-Teleskope :-) Das Bild zeigt meinen ersten Versuch einer Aufnahme mit einem Teleskop der Firma iTelescope.

I finally got the chance for a few nights this month on this wonderful target: A beautiful, if faint, emission nebula between Cepheus and Lacerta and probably my favourite nebula to date - The very small planetary nebula (bottom left) is Abell 79. Abell 79, "The 6 Nebula", is estimated to be at a distance of 5900 to 11,360 lys away. It measures approx 1 arc minute and is magnitude 15. Sh2-132 lies at an estimated distance of about 10,000-12,000 lys and is ca. 40 arc minutes in size. The image also contains the very small planetary nebula G101.5-00.6, which lies to the right of the blue O-III region.

The Crab Nebula (catalogue designations M1, NGC 1952) is a supernova remnant in the constellation of Taurus, it was first identified in 1731 by English astronomer John Bevis. The nebula was independently rediscovered in 1758 by Charles Messier as he was observing a bright comet. Messier catalogued it as the first entry in his catalogue of comet-like objects.
After some observation, noticing that the object that he was observing was not moving across the sky, Messier concluded that the object was not a comet. Messier then realized the usefulness of compiling a catalogue of celestial objects of a cloudy nature, but fixed in the sky, to avoid incorrectly cataloguing them as comets.
William Parsons, 3rd Earl of Rosse observed the nebula at Birr Castle in 1844 using a 36-inch (0.9m) telescope, and referred the nebula as the "Crab Nebula" because a drawing he made of it looked somewhat like a crab. He observed it again later, in 1848 using a 72-inch (1.8m) telescope and could not confirm the supposed resemblance, but the name stuck nevertheless.

I was/am so pleased with how my de-bayered SIGMA fp has performed that I couldn't resist going for a de-bayered SIGMA fp L (61MP). I finally go the chance to try it out in November, having managed to chase down a small hole in the clouds in northern Italy. The conditions were hard: The wind-side of the car was covered with ice before I had finished the set-up, so that I run out of juice before I could get all the data I wanted, nevertheless im still really pleased with the result. There is some really nice "smoking gun" effects in the S-II data that I wasn't aware of before (and didn't see in the 5 minute subs) so I will definitely be looking for an off-center composition next time i'm out ...

The Orion Nebula is a diffuse nebula situated in the Milky Way, being south of Orion's Belt in the constellation of Orion, and is known as the middle "star" in the "sword" of Orion. It is one of the brightest nebulae and is visible to the naked eye in the night sky with an apparent magnitude of 4.0. Located just above the Orion Nebula is the Running Man Nebula.
This image was created from images I captured earlier this year but this time I used PixInsight and Lightroom to get the end result. PixInsight is an excellent piece of software but is complicated and an initial steep learning curve got me to this point. I need to try it on some of the other DSO targets I also captured earlier this year.

Andromeda Galaxy a.k.a. Messier 31
……………..............................................
Andromeda, the largest galaxy in the so-called Local Group of Galaxies to which our galaxy also belongs, is 2.5 million light-years away and can be seen (even with the naked eye) in the constellation Andromeda. As general information, Andromeda is about 1.5 times larger than the Milky Way, with a diameter of 220,000 light-years (compared to the Milky Way which is 120-140,000 light-years in diameter) and contains more than 2 times as many stars. Although the first mention of this celestial object dates from 960, the first to give a more detailed description was the German astronomer Simon Marius, in the 1600s.
It should also be mentioned that Andromeda and the Milky Way are approaching with about 100 miles per second, experts estimate that in about 3-4 billion years the 2 galaxies will collide and thus form a new giant galaxy.
The attached image only shows part of Andromeda because the equipment I used was prepared for another target.

IC 5146 a.k.a. Cocoon Nebula
…………………………..................
IC5146 is a emission/reflection nebula in interaction with a star cluster. The cosmic dust floating around the nebula and the ionized gas by nearby stars form ideal conditions for the formation of new stars, making the Cocoon Nebula a true cosmic nursery.
As general information, IC 5146 has a diameter of about 15 light years and can be seen in the constellation Cygnus, being at a distance of about 4000 light years from Earth.

NGC 2903
.................
Discovered over 200 years ago by astronomer William Herschel, this galaxy is just over 30 million light-years away and can be seen during the spring nights in the constellation Leo. NGC 2903 is very similar to our galaxy in both size ( abt 100.000 light years diameter) and structure, with both galaxies being classified as "barred galaxies”. What makes it stand out (or not, in terms of popularity) is its position in night sky, being a "field galaxy" or solitary galaxy, meaning it is not part of a larger group of galaxies and is not affected by any external gravitational force, thus being gravitationally alone.
I think that, despite its "shy" position in deep space, this galaxy deserves a popular name, especially since it is not an impossible target, a focal length of 5-600 mm being able to bring out some details.

La Nebulosa Crescent si trova nel cuore della costellazione estiva del Cigno, è letteralmente immersa in un "mare" di idrogeno ionizzato in cui sembra galleggiare. Si trova a circa 5000 anni luce dalla Terra ed è formata dalla stella di Wolf-Rayet WR136. Vicino a lei (verso l'angolo in basso a sinistra) si trova la elusiva nebulosa planetaria Ju 1 scoprta dall'astrofilo Dave Jurasevich nel 2007.
Integrazione per oltre 18 ore, pose guidate da 10 minuti con filtro dualband Antlia ALP-T 5nm, mentre per le stelle 52 pose da 1 minuto con filtro broadband SV260, telescopio newton 150/600 con correttore 0.95x, camera Tecnosky Vision 571C, montatura Eq6-R Pro, elaborazione Pixinsight.
The Crescent Nebula is located in the heart of the summer constellation Cygnus, literally immersed in a "sea" of ionized hydrogen in which it appears to float. It is located approximately 5,000 light-years from Earth and is formed by the Wolf-Rayet star WR136. Near it (toward the lower left corner) is the elusive planetary nebula Ju 1, discovered by amateur astronomer Dave Jurasevich in 2007.
Integration over 18 hours, 10-minute guided exposures with an Antlia ALP-T 5nm dual-band filter, and 52 1-minute exposures for the stars with an SV260 broadband filter, 150/600 Newtonian telescope with 0.95x corrector, Tecnosky Vision 571C camera, EQ6-R Pro mount, and Pixinsight processing.
