I tried for the first time the "trendy" software "Topaz sharpen" for this image ; as many users do so now for their astro images.

The process was only applied on the inner core of the galaxy, and with many precautions (mask, low % of blend with the original… ) and rigorous verification that no virtual detail is created during the process. In fact, it was used more like the "sharpen" tool of PS ; which can surely leads to the same result but with many iterations…

For this image, most of the detail come from classic deconvolution and HDR processing on Pixinsight ; Topaz was only useful to quickly give a "sharpen" aspect to the core of the galaxy.

I think that used in that way, and with such precautions, it can be an interesting tool.

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.
