NGC 253 The Silver Coin Star Burst Galaxy with BlurXterminator

The Sculptor Galaxy also known as the Silver Coin Galaxy and is located at the centre of the Sculptor Group, one of the nearest groups of galaxies to the Milky Way.
It is brightest galaxy in the Sculptor group and is one of the intrinsically brightest galaxies in the vicinity of our Milky Way, only surpassed by the Andromeda Galaxy and the Sombrero Galaxy.
NGC 253's star burst has created several super star clusters on NGC 253's centre and star formation appears in the northeast of NGC 253's disk, where a number of red super-giant stars can be found, and in its halo there are young stars as well as some amounts of neutral hydrogen. This, along with other peculiarities found in NGC 253, suggest that a gas-rich dwarf galaxy collided with it 200 million years ago, disturbing its disk and starting the present star burst.

Using Russell Croman's BlurXTerminator is a game changer for work flow and results, but it is a loaded gun for complex galaxy cores like NGC 253.
Out of the box an extraordinary result that does need taming and that will come with time and practise.

I have left the earlier workings of the same data for comparison until I get around to consigning them to the dustbin of history.

Meanwhile re-processing old data helps greatly in dealing with cloudy nights.

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.
