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.

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.

Black Hole Cygnus X-1

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.
