And here it is, the last rendering of the Dark Nebula LDN 1622 - also dubbed the Boogeyman.
The earliest version didn't really match my requirements. Hence this redux from scratch with overall better contrast, details, colors management.
Hope people will like it. I took a special care in the core to make sure that the dark nebula draw the attention needed.
Thank you and very best regards,
Aygen

Milky Way in Cassiopeia and Cepheus
A 24°×35° wide-field view of the Milky Way in constellations Cassiopeia, Cepheus and the north-eastern part of Cygnus is presented in different color composites. This region is full of smaller emission nebulae. For many of them the ionization sources an thus the distance can be determined which provides an insight in the 3D structure of the milky way in that direction.

I traveled 200 km to plan 2 nights of capturing this object and I came across this very bright "star", but the downside turned out to be an opportunity: Mars

47 hours on Sh2-224 (also known as the Rice Hat Nebula).
This is a faint and difficult object to capture in Auriga. I shot this beautiful supernova remnant as bicolor (H + O) and am pleased with the results. The HA overwhelms the OIII when combined so it is important to be careful when bringing out the gases during processing. The processing overall was difficult but fun.

Mock Mirage Sunspots and Green Flashes
Photo description:
At sunset on January 30, I recorded mock mirage sunset and green flashes on Mount Hehuan at an altitude of 3,000 meters. In the mock mirage sunset formed by multiple temperature inversion layers on the high mountain, the sun has various wonderful changes. Because sunspots are very active recently, obvious mock mirage sunspots have also formed! I judged the positions of at least 3 layers of inversion layers through the positions of 3 groups of mock mirage sunspots, which are marked by horizontal dotted lines in the figure. When the top of the sun falls into the inversion layer, it produces a very obvious green flash. The video link of mock mirage sunset is as follows:

In the film, you can see the sun changing layer by layer, and green flashes emerge from the top from time to time. Mock mirage sunspots are also forming at several locations. It is really an amazing mock mirage sunset!

Mock Mirage Sunspots
Photo description:
The mock mirage formed by the temperature inversion layer at sunset on the high mountain makes the sun look like layer upon layer of millefeuille. The original one sunspot has become a whole row of several sunspots! The real image of the sunspot is arranged together with its several virtual images, so it is difficult to judge whether it is true or false. Mock mirage sunspots are really amazing!

Last Sunday, a unique configuration was visible in the sky of Chenonceau (France): the International Space Station was transiting above the castle lit by the half Moon, while the comet C/2022 E3 (ZTF) was traveling in the axis of the stars Dubhe/Merak (Ursa Major) and Polaris (Ursa Minor).
It has been a magical moment, even if the most important for me is not visible on the picture: my second son was with me that evening with his camera and his mini tripod, and for the first time he captured a transit of the ISS!

Amateur astronomers have been obsessed with the comet for days. In Hungary, the weather was not favorable for observing the comet, but on the last two moonless days at dawn, we managed to photograph this wispy celestial wanderer.
In the image, the comet is the main subject: the elongated band to the left is the ion plume, while the comet's plume leaning to the right is the dust plume. What is really surprising, however, are the two galaxies to the upper left of the ion plume. Their distance is enormous... They are ~430 million light years away!!!
The beauty of comet C/2022 E3 ZTF
From the dark skies of the town of Ager in Lerida, I captured the comet C/2022 E3 ZTF, with a 530mm refractor. They were 15x80" exposures with LRGB filters.
Best regards.
After previous two attempts on Jan 20 and Jan 26 which came out nice, I wanted to capture some images on Feb 1 for obvious reasons. Moon and clouds gave me a break on Jan 31 for one hour around 4am. I was waiting several miles away from my house under Bortle 4 with my rig. It was a work weeknight too.
I could only get 1 hour of data before cloud rolled back in and then it was dawn.
Post processing was a big challenge. There were very strong star streaks in stacked comet image from DSS so I was forced to learn comet stacking in PI. Not much different result from PI as well. May be it was because I took 2min exposures and the comet was moving pretty fast. I then took a different route. I removed stars from all cometaligned images and cleaned them up by hand using clone stamp because both StarXterminator and StarNet+ left many stars in. Then I integrated those clean images, did usual noise reduction, stretching and some curves. After that I added stars from the star master light. Here is the result. I hope you will like it.

The idea was to create a mixture of several hours of RGB data with the asi6200mc camera's built-in UV/IR filter and a few hours of narrowband data to enhance the thin lines of the O3 emission regions and highlight the Ha regions without losing the natural touch of the RGB data.

Hi there ! I am super thrilled to share with you my take on the very core of "Messier 16" - dubbed also the "Eagle Nebula".
Messier 16 is a region of active star formation, appearing in the constellation Serpens Cauda.
The Eagle Nebula lies some 7,000 light years away in the Sagittarius-Carina spiral arm of our galaxy - the next arm inward from us.
With regards to the final rendering, the color are applied my mixing three narrowband filters. The colors palette is commonly known as "the Hubble Palette".
I hope you will like it.
CS,
A.

The last 6 seconds of sunset
Photo description:
The last 6 seconds of sunset - the last yellow, green and blue lights line the horizon like pearls!
How does the sun disappear in the last few seconds of sunset? On the evening of January 31, I saw this wonderful sunset on Hehuan Mountain, which is 3,000 meters high. When the sun has fallen below the horizon, we can continue to see sunlight refracted from below the horizon because of atmospheric refraction. In the last few seconds, when there is only one line of sunlight left, because of the different refractive indices of various colors of light, we can see different colors of light—yellow, green, and blue are arranged on that line like pearls! In the last 1 second, they disappeared one by one in front of the camera. First, the yellow light with the smallest refractive index disappears, then the green light, and the blue light with the largest refractive index disappears last. Because the intensity of blue light is the weakest, and the eyes are more sensitive to yellow-green light, so the naked eye could only see a green light disappearing in the sky. What was left at the end was the cheers of everyone who saw the magical green light with their own eyes!
How the pearls of different colors disappear can be seen more clearly in the video. Video link: https://www.youtube.com/watch?v=RJ7vm4g5dXw

IC 2177 - colorful head of the 'Seagull Nebula'
IC 2177 - head of the 'Seagull Nebula'. Such colorful nebula complexes
are among the most visually impressive objects in the night sky.
They are interstellar clouds of dust, molecules, hydrogen, helium and
other ionised gases where new stars are being born.
This object is listed not only in the IC catalog but also in others and known,
for example, as Sh 2-292, RCW 2, Gum 1, ...
