When I first saw the Hubble Space Telescope's "Deep Field" photo of deep space, it was very thought-provoking to me how far humanity can look back in time and space in the universe and how tiny a grain of sand our Earth, our Solar System, and even our Galaxy are in this endless desert that we call the Universe. we're calling! Then, years later, when I got into astrophotography, I looked at the photo again several times and the question became more and more strongly expressed in me, how far back in time would I be able to look back in time with my amateur equipment! My thought matured into a decision at the beginning of 2024 and I embarked on one of the biggest projects of my astrophoto career. One of the goals of the thorough planning was to find one or more very distant objects that I thought I could photograph successfully. After weeks of browsing international galleries and databases, I chose the Abell 1656 (Coma Cluster) galaxy cluster, in the more distant surroundings of which the two selected objects are the galaxy PGC1826187 and the quasar SDSSJ130206.68+281118.9. In order to capture these very distant and faint objects, I knew that I would need a lot of exposure and of course it would not have been enough to take photos from my garden, so I always moved to Mátra in Hungary with dark skies to make the raw ones. Gathering the planned 50-hour expo took 3 months thanks to the clear spring sky with very few moons. The photo is very captivating as we zoom in more and more and the many galaxies are revealed to our eyes! In order to experience this feeling even better, I developed the photo using the highest possible resolution (11934x7618). I did not cut the field of view to fit the two objects on the opposite side. Of course, the two nominated objects, the quasar and galaxy, do not capture the viewer with their sight...since they are just two small gray blobs in the photo...but with the fact that they became visible at all. And why exactly that galaxy and quasar? Because of their extreme distance! The distances are usually determined based on the redshift of the objects, and since I found a lot of wrong calculations in the galleries and in other publications, I turned to an experienced astronomer for help in calculating the "exact" distance between the two objects! I learned from him that for those objects whose redshift is greater than z=0.1, we no longer have to use the traditional formula, but a so-called "relativistic formula" gives an exact value...this is where the many wrong distance determinations come from! According to these calculations, the z=1.295 redshift value of the galaxy PGC1826187 results in a distance of 8.2 billion light years, and the distance of the quasar SDSSJ130206.68+281118.9 based on the z=4.886 redshift value is 12.3 billion light years...these are the values ​​when the light of the objects started towards us ! The Universe has, of course, continuously expanded during its 13.8 billion year history since the Big Bang, and therefore the distance between these objects is now much greater! In the photo, in addition to the pinnacle, there are 83 more quasars more than 10 billion light years away. There are nearly 1,000 galaxies in the picture and approx. 760 quasars are visible, of which the Pixinsight built-in catalogs (NGC-IC, PGC HyperLeda, SDSS, Milliquas 7.2) were able to display 591 galaxies and 377 quasars with captions. At such distances, the average distance of 321 million light-years of the galaxies of the Coma Cluster is almost dwarfed! I wish you good browsing on the picture, and don't forget... YOU MUST ZOOM IN! (Google Translate)
