M42 is a classic of HDR processing. The acronym HDR stands for High Dynamic Range and, with this acronym, we mean a technique that allows us to increase the dynamic range of our sensor, or rather of our image. The dynamic range of a digital sensor is a feature of primary importance for all those photographic genres that include in the photo areas with high brightness variability. Astrophotography is one of the photographic sectors in which we most often, if not always, find ourselves in this condition. In fact, we pass, in the same image, from the intense light of a star to the darkness of the deep sky.
It may happen that in long poses you go to saturate the brightest areas of the image, going to "burn" them, making these areas completely white, losing color and information.
This will happen more frequently the lower the dynamic range of our sensor. But there will still be situations in which it will be impossible to recover certain areas even with very high quality sensors.
It is to overcome this limit that the HDR technique is used. I said that m42 is a classic of this technique, although in my opinion some exaggerate presenting the very dark nucleus almost "venous". I like to keep it bright is still a stellar forge!

The Andromeda Galaxy, also known as Messier 31, M31, or NGC 224 is a barred spiral galaxy approximately 2.5 million light-years Earth and the nearest major galaxy to the Milky Way.[ The galaxy's name stems from the area of Earth's sky in which it appears, the constellation of Andromeda, which itself is named after the Ethiopian (or Phoenician) princess who was the wife of Perseus in Greek mythology.
The virial mass of the Andromeda Galaxy is of the same order of magnitude as that of the Milky Way, at 1 trillion stars. The mass of either galaxy is difficult to estimate with any accuracy, but it was long thought that the Andromeda Galaxy is more massive than the Milky Way by a margin of some 25% to 50%. This has been called into question by a 2018 study that cited a lower estimate on the mass of the Andromeda Galaxy, combined with preliminary reports on a 2019 study estimating a higher mass of the Milky Way. The Andromeda Galaxy has a diameter of about 220,000 light years, making it the largest member of the Local Group in terms of extension.
The number of stars contained in the Andromeda Galaxy is estimated at one trillion (1×1012), or roughly twice the number estimated for the Milky Way.
The Milky Way and Andromeda galaxies are expected to collide in around 4-5 billion years, merging to form a giant elliptical galaxy or a large lenticular galaxy. With an apparent magnitude of 3.4, the Andromeda Galaxy is among the brightest of the Messier objects, making it visible to the naked eye from Earth on moonless nights, even when viewed from areas with moderate light pollution.

It had been a long time since I wanted to challenge myself with a mosaic, and with the arrival of the summer sky, it was easy to point towards the constellation of Cygnus. So, I aimed my lens towards the North America and Pelican Nebulae. Initially, I wanted to exclude Deneb from my composition as my narrowband filters from Optolong don't handle such bright stars very well. However, considering the various combinations of frames, I liked the presence of the Cygnus's beacon, so I decided to include it, trying to manage it as best as I could. I hope you like the result.

Messier 35 is a large open star cluster 2,800 light-years away that can be seen near Castor's right foot in the constellation Gemini.
M35 - or NGC 2168 as it’s also known - probably contains about 500 stars, and is thought to be about 100 million years old. This might seem very old, but it is relatively young in astronomical terms.
Open star clusters are indeed young objects, generally speaking, especially when compared to globular clusters, which can be as ancient as 12 billion years old.
Messier 35 shines at mag. 5.2, which means it can be seen with the naked eye under dark conditions, but viewing through binoculars or even a small telescope will begin to reveal its sparkling beauty.
The cluster is part of the famous Messier Catalogue conceived by Charles Messier in the 18th century, but it is the only Messier object in the Gemini constellation.
NGC 2158 is also located in Gemini and looks as thought it's right beside M35, but in actual fact it is much further away, at 14,700 lightyears distant.
NGC 2158 is also much older, at 2 billion years old.

Messier 81 (also known as NGC 3031 or Bode's Galaxy) is a grand design spiral galaxy about 12 million light-years away, with a diameter of 90,000 light years, in the constellation Ursa Major. Due to its proximity to our galaxy, large size, and active galactic nucleus (which harbors a 70 million solar mass supermassive black hole), Messier 81 has been studied extensively by professional astronomers.

Images published on the web tend to show the oxygen areas in an electric blue and the Ha areas in a hue closer to pink
while it was possible to achieve this colour palette by using adjustment layers (Hue/Saturation, colourise) I have chosen to go with the image more or less as it emerged from PixInsight

The Eagle Nebula (M16). This is one of my favourite objects, but it's hard to image because it's so low in the sky and only makes a brief unimpeded appearance. This shoot took place over two nights (I had wanted to do more, but shooting into the worst of London's light pollution just became too frustrating). Maybe I'll add more data next year.
[From Wikipedia]The Eagle Nebula (catalogued as Messier 16 or M16, and as NGC 6611, and also known as the Star Queen Nebula) is a diffuse emission nebula and a young open cluster of stars about 5700 light-years away in the constellation Serpens. Both the "Eagle" and the "Star Queen" refer to visual impressions of the dark silhouette near the center of the nebula, an area made famous as the "Pillars of Creation" imaged by the Hubble Space Telescope. The nebula contains several active star-forming gas and dust regions, including the aforementioned Pillars of Creation. The Eagle Nebula lies in the Sagittarius Arm of the Milky Way.

VdB 16 is a small blue reflection nebula in the constellation Aries. It is illuminated by the 9 mag. star HIP 16170 with spectral class F. The nebulous region illuminated by the star is part of a large nebulous complex of gas and dust known as the Perseus Cloud. You can see some dark nebula as B 204. The distance to the Solar System is estimated 980 light years.

My very first attempt at capturing planetary images with my setup, using the Newton 200 F5 in combination with the little QHY5 mono camera that I normally use for guiding. Lots of problems due to the poor seeing conditions (very strong winds) and I did not have the right adapters to mount a Barlow in front of the filters wheel, but hey! This is the first try! Lots of room for improvements from here! :-)

Processing note
1.stacked Ha and OIII data in AAP separately
2. stretched in APP- most aggressive stretch applied to Ha data, less agressive to OIII
3. Noise reduced using NoiseXterminator
4. HOO image created in APP using HOO1 algorithm
5. curves and levels in Photoshop
Needs more data! ideally from a dark site but from Bortle 6, maybe double - say another 10 hours

Processing notes
Stars removed with Starnet++. Star layer created by subtracting the starless version from the stacked image from APP. (Layer mask used to reveal globular from stacked image in the star layer)
starless image processed as usual with curves and levels after noise removal and Star layer added back in photoshop
despite the dark location object was relatively low so gradient removal was found necessary
Definitely needs more data- another two hours wouldn't go astray

La Galassia di Bode, (nota anche come M 81 o NGC 3031) è una galassia a spirale situata a circa 12 milioni di anni luce dalla Terra, nella costellazione boreale dell'Orsa Maggiore. Si stima che M81 contenga approssimativamente 250 miliardi di stelle, è quindi leggermente più piccola della nostra Via Lattea. Questa e la vicina galassia irregolare M82 sono i membri più importanti del gruppo di galassie di M81, di cui la stessa M 81 è il membro principale; sembra che le due galassie si siano incontrate qualche milione di anni fa, causando la deformazione di M 82. Tuttora le due galassie sono separate da appena 200 000 anni luce. La sua distanza è ben nota ed è stata stimata in 12 milioni di anni luce. La Galassia Sigaro (nota anche come M 82 o NGC 3034) è una galassia attiva nella costellazione dell'Orsa Maggiore, anch'essa si trova a circa 12 milioni di anni luce. Si tratta di un ottimo esempio di galassia starburst.
