Galaxy M94

Image Title: Galaxy M94

Image Description and Details : For this image of the M94 Galaxy, 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.
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.
