My photo was selected as a cover picture of the Official Year Calendar of Vatican Observatory 2025
The Vatican observatory selected my photo of Sharpless 157 as a cover picture of an Official Calendar of the Vatican Observatory.
I have had my photos in this yearly published calendar about ten times and this is a second time my photo was selected as a cover, first time was back in 2019, the cover picture can be seen here: https://astroanarchy.blogspot.com/2018/12/astro-anarchy-gets-published-cover.html

All of my photos from the Year 2024
As usually, I'm publishing a poster format presentation of my photos at end of the year. This time all of the material is shot at Autumn Season 2024 since I got my new imaging platform up and running by then.
I haven't been able to produce any new material for almost three years due to some health problems. After hard times I'm back and well again.
Building a new imaging system fully functional took couple of years. It's working now very well, only some small tweaking has to be done next year, I'll do it during the mandatory Summer pause of six months.

Sharpless 132, A closeup
I published my latest photo out of Sh-2132 emission nebula just few days ago.
Now I'm publishing a "Spinoff" image out of it. Since the photo was a very high resolution one, I'm able to cut out a new composition out of it. The cut out has a resolution of 4000x4400 pixels.

Sharpless 132, A Furious Cosmic Horse Gets Blinded by a Divine Blue Light
This is one of my favorite targets in Cepheus, Sh2-132 has an interesting structures due to massive energetic stars in it. I haven't found any explanation to the blue, jet like, structure glowing blue light of ionized Oxygen (O-III), the structure is visible also in H-alpha light.
When I shot firs photos out of this distant object about twenty years ago, I gave a longish name to it, "A Furious Cosmic Horse Gets Blinded by a Divine Blue Light" I don't usually name my photos but with some of them I simply must do so.
This is a kind of high resolution photo taken with my new imaging platform, it covers about 0.7 x0.7 degrees of sky. (Full Moon has an apparent diameter 0,5 degrees) Seeing was very good to my location, FWHM about 1.6 arcseconds, that's rare up here.

INFO
Sharpless 132 (Sh2-132) is powered by two massive stars, each with a mass over 20 times greater than our Sun. Formed from shells of ionized gas that have expanded, the nebula's energetic matter not only glows, but is dense enough to contract gravitationally and form stars. The angular size of the Lion Nebula, officially named Sh2-132, is slightly greater than that of the full moon. The gaseous iconic region resides about 10,000 light years away in a constellation named after the King of Aethopia in Greek mythology.

Pansy of the Swan, Sharpless 112
My previous image was showing the Sharpless 115 an emission nebula area in Cygnus, just next to it lays another Sharpless catalog target, Sh2-112.
My new photo about Sh2-112 has O-III and S-II data from my older image of Sharpless 112 from the October 2015. The new H-alpha data is much deeper and has a higher resolution. For some reason, this target has always been very difficult to process. Details in a background are very diffused and the actual emission nebula has a vast dynamic range, from a very bright to a very dim features.
I renamed this target to a "Pansy of the Swan" since the bright nebula looks like a blooming yellow pansy.

Sharpless 112 (Sh2-112) lays in the Cygnus, the area rich in Ha, approximately 5000 light years away. Its location is full of faint nebulosity, as seen in the background of my photo. The nebula is energized by a hot, young star, BD +45 3216, which emits large amounts of UV light causing the gases to glow light.

New Photo, Sharpless 115 in Cygnus
This Portion of sky covers less than a square degrees of sky in Constellation Cygnus, the Swan.
This star nursery has always looked to me like like it was cut out of the Baroque painting.
I was able to shoot a high resolution data for it with my new imaging setup. The Celestron Edge 14". This telescope has a beautiful optics and with a secondary mirror focuser, it'll hold the collimation perfectly all the time. Normally the heavy main mirror is used for focusing and it can be source of optical problems when it moves due to gravity when the scope is moving and pointing to a different portions of sky.

INFO
Sharpless 115 stands just north and west of Deneb, the alpha star of Cygnus, the Swan, in planet Earth's skies. Noted in the 1959 catalog by astronomer Stewart Sharpless (as Sh2-115) the faint but lovely emission nebula lies along the edge of one of the outer Milky Way's giant molecular clouds, about 7,500 light-years away.
Shining with the light of ionized atoms of hydrogen, sulfur, and oxygen in this Hubble palette color composite image, the nebular glow is powered by hot stars in star cluster Berkeley 90. The cluster stars are likely only 100 million years old or so and are still embedded in Sharpless 115. But the stars' strong winds and radiation have cleared away much of their dusty, natal cloud. At the emission nebula's estimated distance, this cosmic close-up spans just under 100 light-years.

Wizard Nebula, NGC 7380
My new setup has a long focal length optics, Celestron EDGE 14", after years of shooting the wider field astronomical photos, it's very nice to dig in to the details of those cosmic wonders.
My new photo shows the Wizard nebula in Cepheus, I have shot this target many times with a various optical configurations. The combination of 14" telescope and large 12 micron pixels of my "new" second hand camera, Apogee Alta U9000M, delivers an optimal resolution to my seeing conditions (0.91 arcsecond/pixel). This makes possible to go very deep in relatively short cumulative exposure time, as can be seen in this photo. A dim background nebulosity stand out nicely after about six hours of H-alpha exposures.

INFO
NGC 7380, the Wizard Nebula, locates in constellation Cepheus at distance of about 8500 light years from us. The Nebula surrounds an open star cluster NGC 7380. Stars, gas, and dust has created a shape that appears to some like a fictional medieval sorcerer. The active star forming region spans about 100 light years, making it appear larger than the angular extent of the Moon. The Wizard Nebula can be located with a small telescope toward the constellation of the King of Aethiopia (Cepheus).

Beauty and the Beast, Tulip Nebula and a Black Hole
I started to collect exposures for this photo back in 2014, now I have shot new high resolution material for this amazing target with my new imaging platform.
I see several layers in my photos and that makes them to tell a story beyond any imagination.
First
A visual layer, that's naturally very important to me as a visual artist, revealing the hidden cosmic beauty and poetry is my passion.
Second
The physical layer, how emission of the nebulae works, radiation pressure, nuclear fusion of the star, gravitational phenomes, etc... all that is extremely beautiful in its own class.
Third
An existential layer, where we are coming and where we are going in a cosmic scale.
Practically all of the heavier elements in our bodies are coming from supernova explosion's, iron in our blood, oxygen, carbon, etc... We are children of the stars
When our Sun will die after few billion years and turn to a planetary nebula, it'll vaporize the Earth and our remains on it and blows them to the outer space. After aeons our remains are going to end up to a building blocks for a new generation of stars.
We all have been stars and one day we going to be stars again.
This is the beauty and poetry I'm after my photos

Black Hole, Cygnus X-1, is marked in the photo
INFO
The complex and beautiful Tulip Nebula, Sharpless 101, blossoms about 8,000 light-years away toward the constellation of Cygnus the Swan. Ultraviolet radiation from young energetic stars ionizes the atoms and powers the emission from the Tulip Nebula.
Also in the featured field of view is the black hole Cygnus X-1, which is also a microquasar because it is one of strongest X-ray sources in planet Earth's sky. The powerful jets from the black hole can't be seen in this photo since they glow light in X-ray wave length. Faint bluish curved shock front, visible at up center, is coursed by the X-ray jet when it hits to a interstellar gas and dust.
Why we can see the black hole in this image as a star like object?
We can't see the actual black hole but we can see how the material is twirling in the black hole. The speed become so high that the matter starts to turn to an energy emitting light trough the whole spectrum up to X-ray and gamma radiation.

Astro Anarchy get published
After about three years without shooting new material from the night sky I'm finally back in business.
I had some health issues and after three operations I'm starting to be good as new again. I have also built a new imaging system, it took about two years to get it up and running.
I was really amazed about the amount of publicity my work got after I publish my first photos from the new setup. Here are some of the publication, couple of them are in finish only, sorry.

Methuselah Nebula, MWP1, project finalized
Planetary Nebulae are like candy of the cosmos, small and colorful treats to the eye.
MWP1 is a Planetary Nebula in constellation Cygnus, the Swan, it's rarely imaged and now I know why.
This is a unusually old, unusually shaped and unusually large planetary nebula, it also was one of the most difficult targets I have captured so far.
When I saw the first 20 min. exposure, it looked like there is plenty of nothing in the frame, this is dim to an extreme. I have added full size 20 min sub frames of H-alpha and O-III at the end of this blog post so you can see yourself how much data there is.

INFO
This is one of the largest planetary nebulae known, it spans about 15 light-years. Based on its expansion rate the nebula has an age of 150 thousand years, a cosmic blink of an eye in the 10 billion year life of a sun-like star. But planetary nebulae represent a very brief final phase in stellar evolution, as the nebula's central star shrugs off its outer layers to become a hot white dwarf. In fact, planetary nebulae ordinarily only last for 10 to 20 thousand years.
The central star of the nebula is on of the hottest stars known. It's so hot that it's producing large amounts of X-rays
