      Description

      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.
