Centaurus A (NGC 5128) A Starburst Galaxy in RGB

Centaurus A (NGC 5128) is a starburst galaxy in the constellation of Centaurus and is one of the closest radio galaxies to Earth and the fifth-brightest galaxy in the southern sky.
It contains a supermassive black hole with a mass of 55 million solar masses, which ejects a relativistic jet whose inner parts of the jet are moving at about half of the speed of light.
The X-ray jets of Centaurus A are thousands of light-years long, while the radio jets are over a million light-years long. It probably resulted from the collision of a large elliptical galaxy that collided with a smaller spiral galaxy which is suspected to be responsible for the intense burst of star formation.

Using the new Pixinsight tools including Spectrophotometric Color Calibration, Normalised Scale Gradient, and Generalise Hyperbolic Stretch on a more ruthlessly culled data set provided a more stable platform for applying the finishing touches and a much better result than last year from the same data.

Who needs clear skies when you can go back revisiting old data with the next generation of tools on new hardware that slashes the amount of time it takes to process this stuff?

I do ... But my offerings to the weather gods are being ignored and virgins are getting scarce.

The “AstroBin Image of the Day and Top Picks”, or IOTD/TP, is a long-running system to promote beautiful, interesting, peculiar, or otherwise amazing astrophotographs, with a focus on technical excellence. Learn more.

Submitted The date and time when you submitted this image for IOTD/TP consideration.	...
Views by Submitters (available since September 19th, 2023) Every image is assigned to 50% of available Submitters. In the event that at least 80% of them don't view the image before its time in the IOTD/TP process expires, it's assigned to the other 50% of Submitters and the process begins anew.
Promotions by Submitters When 3 distinct Submitters promote the image, it moves on to the next stage of the process: evaluation for Top Pick status. This requirement, in addition to anonymization of images and distribution to only a subset of them, prevents biases and ensures that the best images are selected.
Promotions by Reviewers When 3 distinct Reviewers promote the image, it moves on to the next stage of the process: evaluation for IOTD status.
Early dismissal Staff members have a lot of images to inspect on a daily basis, and they can dismiss images if they believe they don't meet the requirements for IOTD/TP selection. If an image is dismissed 5 times, it's removed from the process. This streamlines the process and ensures that any bias present in promotions could be overruled by other staff members.
