Chandra Space Telescope image of Centaurus A and its structure. The white diagonal line is the jet from black holes in the center of the galaxy.
I spent a bit more time reprocessing this one again. This time it appears much more restrained and with significantly less sensor noise. I much prefer this version.

This chart shows the location of the peculiar galaxy Centaurus A (NGC 5128) in the constellation of Centaurus (The Centaur). This map shows most of the stars visible to the unaided eye under good conditions, and Centaurus A itself is highlighted with a red circle on the picture. This galaxy is quite bright and can be seen well in small amateur telescopes or even binoculars. The dark band is also clearly visible in somewhat larger telescopes.
Won the Overall Photographer of the year Award as well as Winner in the Deep Space Category for the Royal Astronomical Society of NZ Astrophotography competition. It was the only deep space image I finished this year but put a lot of effort in it across 2 years so very glad it has been recognised.
Big thanks to Amit Ashok Kamble for running such a smooth comp and making it even easier to enter, Dylan O'Donnel for the judging and special mention to my friend Kavan Chay who encouraged me to at least enter this one when I was really adamant to not enter any any competitions this year.
Judges description (Dylan O'Donnel):
Amrit’s incredibly deep exposure of the close galaxy Centaurus A has truly paid off for the two years he collected data in order to produce this image and reveal the outer glow and the relativistic jets that are difficult to see in visible light. This kind of image is altogether uncommon but has not been selected merely for effort but for the careful processing, contrast and colour Amrit has pulled out of the image. Congratulations on winning the Deep Sky category.

Image description:
Stared at a black hole for 120 hours over a year and this is what I ended up with. Centaurus A is a bright galaxy with a supermassive black hole in the middle of it. I tunnel visioned into a dark rabbit hole to capture the rarely imaged filaments and much to my surprise even got a smudge of the rarer Southern Jet. As these details are faint, they take a lot of effort to capture amidst light pollution. With my luck, most of the clear nights I had were with the moon out which washed the sky out but you take what you can get with the way the years been. People from darker sky areas, bigger & faster scopes will be able to do better with half the time. I hope to stack on more hours to this project in future years before calling it finished but moving to other objects for now. There is a lot I'm not happy about with this, but that's what happens when you take a year off - forgetting the processing workflow and trying to deal with a complex dataset that comprises many nights data spanning over 12 months, lots of mixed light pollution & moon gradients to deal with.
Have included shots of the wider area along with an annotated copy which labels approx 80 known galaxies in the background from NGC/PGC catalogues as well as labelled the Jet and filaments. Also featured a closer crop as one of the biggest advantages of the longer integration time was that I was able to selectively stack the sharpest data and produce a relatively decent resolution with my tiny but mighty Esprit 100mm refractor telescope from Skywatcher.

This time with 20 sub exposures of 2 minutes each. Now showing a little more detail in the central galaxy.
Centaurus A, also known as NGC 5128, is well known for its dramatic dusty lanes of dark material. Hubble’s new observations, using its most advanced instrument, the Wide Field Camera 3, are the most detailed ever made of this galaxy. They have been combined here in a multi-wavelength image which reveals never-before-seen detail in the dusty portion of the galaxy. As well as features in the visible spectrum, this composite shows ultraviolet light, which comes from young stars, and near-infrared light, which lets us glimpse some of the detail otherwise obscured by the dust.

Nuevo intento a la galaxia Centauro A (NGC5128), esta vez con el #Evostar72ED.
Esta galaxia se encuentra a casi 15 millones de años-luz de distancia.
226 lights + 32 darks que dan como resultado unas 2hs de datos.
Procesado: DeepSkyStacker + GIMP
Primer intento a NGC5128 (Centaurus A).
Está situada en la constelación Centauro, a unos 15 millones de años-luz de distancia.
Fue descubierta en 1826 por James Dunlop desde Australia.
La banda negra característica es el remanente de una galaxia más pequeña que absorbió.
La foto fue tomada sin telescopio.
Canon T2i con un lente vivitar de 210mm sobre una montura motorizada.
Procesado: DeepSkyStalker + Gimp
Es una combinación de:
190 lights F8 ISO1600 30s + 29 darks
14 lights F8 ISO800 120s + 6 darks
Edited NOIRLab image of Centaurus A.
Original caption: The galaxy Centaurus A, which lies over 12 million light-years away in the direction of the southern-hemisphere constellation Centaurus (The Centaur), is the leading light of this striking image. This image provides a spectacular view of the luminous glow of stars and dark tendrils of dust that hide the bright center of the galaxy. This dust is the result of a past galactic collision, in which a giant elliptical galaxy merged with a smaller spiral galaxy. As well as large amounts of gas and dust, Centaurus A’s dust lane contains widespread star formation, as indicated by the red clouds of hydrogen and by the large numbers of faint blue stars visible at each end of the dust lane. Zoom into the image to see more.
